Grundfos Pumps

  • Why Grundfos pumps are an industry leader

    Few pumps manufacturers have distinguished themselves so definitively from Grundfos Pumpsthe rest of their contemporaries as Grundfos. The Danish manufacturer set up shop under the slightly more unwieldy moniker of Bjerringbro Die-Casting Foundry and Machine Factory in 1945, and ran through a series of names before finally settling on Grundfos in 1967. Throughout its decades of operation, Grundfos has been able to maintain its reputation as an industry leader, but how? Is it their ability to innovate? Is it the infallible quality of their products? Or is it simply the prestige their storied history lends their pumps? We are of the opinion that all of these factors - amongst many others - are helpful in explaining the esteemed status Grundfos holds today.

    Innovation

    To this day, Grundfos takes its commitment to pioneering new pumping technologies very seriously. The Grundfos Lifelink project is a reflection of this commitment. A plan to improve water infrastructure in the developing world, Grundfos Lifelink leverages mobile connectivity to improve reliability for both water service companies and end-users. The project has been a great success thus far and Grundfos’ foresight to integrate innovative mobile connectivity into the supply of water has been revolutionary.

    Quality

    The name Grundfos has always been synonymous with quality. Even some of the very first pumps Grundfos created were incredibly well-received - noted both for their durability and their efficiency. Grundfos haven’t shied away from this tradition either; they have continued to put out products of exceptional calibre year after year. As a stockist of a great many of their products, we are more than well positioned to verify this. From Grundfos home boosters to Grundfos central heating pumps, a tremendous quality permeates from every product that bares their insignia.

    Corporate responsibility

    Admittedly, the size of Grundfos - and the scale of the resources they have at their disposal - puts them in the unique position of being able to take their corporate responsibilities seriously. Nevertheless, they have been able to put the resources they have committed to this task to exceptionally good use. On their website, Grundfos divide this responsibility into two distinct camps - a promise to their customers and a promise to society as a whole. For their customers, Grundfos promise to continue to innovate. For society as a whole, Grundfos are dedicated to minimising their environmental footprint and seeking sustainable solutions wherever possible. This awareness of a duty that goes beyond their shareholders distinguishes Grundfos from other manufacturers in their field, and is a contributing factor in their continued success.

    Aside from the rest of their attributes, quality will always be a priority for customers and it is ultimately what makes Grundfos such an undeniably huge success and one of our bestselling manufacturers. You will find an extensive range of affordably priced Grundfos pumps on our website. If you have any questions or queries about any of these products - whether it is something that seems unfathomably complex or incredibly simple - please do not hesitate to get in touch with a member of our team to double check.

  • Three water reclamation systems you need to know

    Grundfos pump unilift 150 a1 Grundfos Unilift 150 A1 submersible pump

    As our constant search for sustainable methods of using water continues, more and more viable solutions seem to emerge. In this post, we will delve into three of the most popular - rainwater harvesting, greywater recycling and seawater desalination. Without these techniques, we run the very real risk of exhausting the world’s natural supplies of potable water. And the better we are able to understand and harness these techniques, the more likely we are to be able to properly manage and maintain our resources for future generations.

    Rainwater harvesting

    The most widely practised water reclamation technique is rainwater harvesting - and it owes its popularity to its simplicity. At its most rudimentary, it can involve nothing more than a bucket being placed outside. More complex alternatives are available however, and an astroturf lawn fitted with a water collection tank is perhaps the most elaborate example. One of the most practical rainwater harvesting methods is to install a water butt. Positioned at the base of a downpipe, a water butt will simply sit and collect rainwater, which can then be repurposed for use throughout the home at a later date.

    Grey water recycling

    Greywater refers to the relatively clean wastewater that emerges from baths, sinks, washing machines and other similar appliances after use. Unlike rainwater harvesting techniques which are comparatively simple, because of the recirculating that is necessary in grey water recycling, their systems are slightly more complicated - and, as you would expect, slightly more expensive. At Pump Sales Direct, the grey water recycling systems we have available are affordable and effective. You are just a few clicks away from reducing your home’s water usage by up to 50%. Accompanying any decline in your home’s water usage is a similarly healthy drop in your home’s water bills - proving that the installation of a grey water recycling system pays dividends financially as well as environmentally.

    Seawater desalination

    Seawater desalination is the most expensive and laborious technique for recovering usable water on this list - so much so that it has to be undertaken on a massive scale to prove financially viable. As one of the few truly rainfall-independent water sources, seawater desalination, for many areas, is an indispensable part of their water supply. In Kuwait for example, the water produced by seawater desalination provides 100% of their water use. The method by which this process is carried out varies from plant to plant. Amongst the most popular however, are: distillation, forward and reverse osmosis, and electrodialysis.

    Water reclamation technologies from Grundfos

    Grundfos, one of the best known manufacturers in the industry, produces a variety of pumps that are suitable for use in water reclamation - both domestically and commercially. Their range of wastewater submersible pumps are of the utmost quality and the addition of one to your home will undoubtedly bolster its ability to reclaim water - the Grundfos pump unilift 150 a1 is just one example. If you have any questions about any of our products, please do not hesitate to get in touch by phone, email, or through the contact form on our website.

  • How long do shower pumps last?

    Grundfos shower pumps

    A shower pump can have a transformative impact on the quality of the showers in your home. There can however, be an imposing number of barriers to acquiring a quality and affordable pump that perfectly services your home. A shower pump is a sizeable investment and you want to be sure that every penny that you do put towards it is worth it. Acquiring a top of the range product that services your home perfectly is essential. With this in mind, we have put together this guide that answers many of the most common questions and queries that people have when it comes to Grundfos shower pumps. There are a number of inherent factors that affect the lifespan of shower pumps but it is worth noting that there are external factors that also play a role.

    Brand name

    A well-respected and well renowned brand name is often a signifier of quality and the same is true for shower pumps. At Pump Sales Direct, you will only find products from leading manufacturers, meaning that you can rest assured that each and every purchase you make is a worthwhile investment.

    Water quality in your area

    The hardness of water is dictated by the levels of dissolved minerals that are present within it. High volumes of magnesium and calcium make hard water particularly reactive - leading to a plethora of inconvenient outcomes. Washing your hands with a combination of soap and hard water is likely to leave behind a residue of sorts. Similarly, in the presence of heat, dissolved calcium reacts to form solid carbon carbonate, which is why hard water leaves behind scale in heating equipment throughout the home. Because of this reaction, the harder the water is in your area, the quicker your shower pump is likely to deteriorate. Therefore, the lifespan of a shower pump can be reduced by the quality of your water supply.

    So, what is the average lifespan of a shower pump?

    Typically, excepting the influence of all the aforementioned factors and any other uncontrollable interruptions, you can expect a shower pump to last for somewhere around eight years. Of course, this is just a generalised observation and if you are looking for further indication of the durability of the shower pump you are buying, you are best checking the duration of the warranty that has been offered to you. A warranty more or less guarantees the product’s survival. At Pump Sales Direct, the vast majority of our shower pumps are protected by comprehensive two year warranties.

    Where to direct any further questions and queries you may have

    If you feel any of your questions have been left unanswered, or if you simply need further explanation or clarification, please do not hesitate to get in touch. Our dedicated team are ready and waiting to field any of your questions and queries. Call us on 0800 008 6405, email us or use the contact form on our website.

  • How do drainage pumps work?

    drainage pumps

    Drainage pumps are often installed to move waste-water from a range of domestic and industrial sites, including private housing, farmland, and construction sites. They deal in underground dewatering, usually when gravity can't be applied to move the water (in this respect a drainage pump is similar to a sewage pump). What a drainage pump does is effectively ‘what it says on the tin', however, how they do it is a different matter entirely. This article aims to introduce the how's and why's of non-submersible and submersible drainage pumps.  

    Non-Submersible Drainage Pumps

    A non-submersible drainage pump is not placed directly in water; instead, it uses suction hoses and permanent pipework to transport the waste-water from the unwanted location. This type of drainage pump is often used when pumping waste-water from ponds, and other mobile drainage requirements.

    Submersible Drainage Pumps

    The reputable pump manufacturer Grundfos defines the submersible pump as "an enclosed unit with a close coupled pump and motor, due to its construction, the pumps are suitable for submersible installations – designed to be partially or completely immersed in water."

    A submersible drainage pump will collect water from the base of the unit and transport the water up and out of the system and include a no return valve to ensure there is no potentially damaging backflow. To use the ABS Coronada 250W-SX as an example, it is optimised to work when submerged in several ways. Firstly, the unit is encased in corrosion resistant stainless steel which is vital for the products durability – the model is also equipped with thermal sensors in the motor to prevent overheating. The Coronada is also equipped with the previously mentioned no return valve.

    The Calpeda GXRm 11 fits the similar purpose of draining rooms, water extraction, and can also clean water containing solids of up to 10mm in size. Its operating systems differ in various ways from the Coronada, for example in the Calpeda the motor is cooled by the water passing between the motor jacket and external jacket. However, both jackets are similarly corrosion proof – making both these submersible drainage pumps excellent units for domestic use.  

    Submersible Drainage Pumps & Industrial Use

    An industrial site naturally includes different working conditions when compared to the domestic setting – the Trencher T400F automatic submersible drainage pump is an excellent example to consider concerning industrial conditions.

    Whilst this pump is undoubtedly suited to a residential environment, what makes it uniquely suited to industrial sites is its adept handling of water supply from lakes and rivers. The Trencher is excellent when dealing with sediment removal thanks to its high abrasive resistance resin vortex impeller– which is something more common in industrial sites that often handle raw materials, thus this feature is less likely to be needed in a suburban estate.

    Every pump adheres to its specifications and operating systems, they often share a common purpose but when looking at the ‘how', one must look carefully at the detailed specification pdf's that are regularly available to select the correct drainage pump for you.

  • How does a coolant pump work?

    Think you might need a coolant pump? You’ve come to the right place. By coolant pumpleaning on our years of experience in the pumps industry, we have created this post that will tell you everything you need to know about coolant pumps. For everything from sizing requirements to compatibility with different materials, you’ll find it all here.

    What is a coolant pump?

    As you can probably guess by the name, the role of the coolant pump is to ensure that coolant is distributed evenly throughout the structure in which it is situated. Coolant is any substance (generally speaking a liquid or gas though) that is used to regulate the temperature of a system. In industrial processing, the term ‘heat transfer fluid’ often replaces the term ‘coolant.’ Coolant pumps are used in a range of industries, which has led coolant pumps to specialise in a number of different ways.  Typically though, a coolant pump is a submersible multistage centrifugal pump. Put in simpler terms, a coolant pump is capable of operating fully submerged in liquid, and works by imparting energy from the rotation of multiple shaft-driven impellers to the coolant.

    Secondly, it is important to differentiate machine tool coolant pumps (which are the kind we deal in here at Pump Sales Direct) from the coolant pumps you might find in your car, or further still, in a nuclear reactor. Although functionally similar - they all work by pumping a coolant around - there are a number of subtle differences that distinguish them from one another in practice. A coolant pump designed for a pressurised water reactor for example, is more elaborate and technical as it needs to be able to transfer heat in a steam generator to water across different pressure circuits. Meanwhile, in car engines and machine tools, the role of the coolant pump is more straightforward as they are only needed to circulate coolant irrespective of pressure differentials.

    How do I know if I need a coolant pump? And if so, what kind do I need?

    Because coolant pumps have so many industrial applications (everything from boiler feeds to industrial washing machines) it can be difficult to work out whether you actually require one, and narrowing it down to a specific model can be even tougher. However, once you have established your flow, pressure and length requirements, picking out the right coolant pump is relatively uncomplicated. On the other hand, if you are still unsure when it comes to the technical details, the flexibility of the Grundfos range of SPK coolant pumps makes them a feasible choice in a multitude of scenarios.

    At Pump Sales Direct, alongside the very popular Grundfos SPK range, we stock a variety of machine tool coolant pumps. Have a look at this extensive range of machine tool coolant pumps here.

  • Innovative Ways to Keep Your Home Warm this Winter

    With the days getting shorter and the nights getting longer, more and more of us are reaching for that extra blanket or hot water bottle in a desperate attempt to cut back on our energy bills. More often than not though, these attempts are in vain. But what if I told you there are a number of simple and cost-effective ways you can keep your home a few degrees warmer without breaking the bank?

    Grundfos Magna 32

    DIY draught excluders

    In the modern age, it is easy to obsess over increasingly intricate and complex technologies and how they can make our lives better - and the same certainly applies to heating. But sometimes we are better off looking to the past and the use of draught excluders is one such example. Designed to prevent heat escaping from beneath your door, draught excluders are a necessity for a pleasantly warm home. If you are feeling particularly money savvy, you can easily create one of your own using nothing more than an old pair of tights and a few socks.

    Imitating double glazing

    You don’t need to shell out on double glazing to reap the rewards of it. In spite of its garish appearance, bubble wrap is a surprisingly effective alternative to double glazing. Thanks to its insulating properties, it is a more than worthy mimic. By coating your windows with bubble wrap, you can keep your home considerably warmer. Because of its appearance though, it certainly isn’t going to appeal to everyone. There is another option for the more aesthetically conscious - a transparent film.

    Capturing sunlight during the day and keeping it trapped at night

    If you aren’t going to rely on conventional heating methods during the winter months, you have to make the most of what little sunlight is available to you. The most effective - and simplest - way to do this is to open your curtains during the day and close them during the night. Any sunlight that filters into your home during the day will have a warming effect and closing your curtains or blinds when the sun goes in will ensure as much of the heat is retained as possible.

    Installing the right heating pump

    As much as you can maximise the temperature of your home using a variety of DIY methods, there is no substitute for a quality heating pump. The Grundfos Magna 32 is a stellar example. As an ‘A’ rated circulator, it is widely recognised as one of the best on the market today - and it owes this status to its efficiency. It uses up to 80% less energy than a ‘D’ rated circulator, culminating in an annual saving for the average household of around 10% on electricity. Whilst saving both energy and money, the Magna 32 will ensure that you have hot water whenever you need it - whether that be to run a hot bath or to switch on a radiator.

  • An Introduction to Agricultural Irrigation

    For the unfamiliar, agricultural irrigation is the manual application of water to land for the purpose of growing and sustaining crops. What sounds like a simple process is actually bewilderingly complex at times. With climate and crops differing by region, a variety of irrigation techniques have emerged, which, while useful, also serves to complicate matters further. To help you sift through the confusing world of irrigation, we have produced this guide to the most popular, effective and efficient techniques.

    Flood irrigation

    flood irrigation

    Flood irrigation is the oldest and most inefficient form of agricultural irrigation. As its name suggests, flood irrigation essentially consists of allowing water to flow freely through a field of crops. Its haphazard application makes it an attractive choice for farmers that are reluctant to splash out on a complicated (and sometimes expensive) delivery system of pipes and pumps, but it also makes it extremely inefficient. Over half of the water intended to nourish crops is actually lost to evaporation, run-off, transpiration and infiltration of unintended areas, making flood irrigation a poor choice for those who are environmentally conscious.

    Pressurised irrigation

    Unlike flood irrigation, which can occur almost without human intervention, drip and flood irrigation is reliant on an elaborate system that provides them with a supply of pressurised water. Composed of a water source, a pump that is capable of pressurising the water, as well as a means of actually transferring water to the crops; pressurised irrigation systems are far more complex than their flood irrigation counterparts. This complexity allows pressurised systems to be far more efficient and effective, but it also makes them far more likely to break down.

    Drip irrigation

    self priming pump

    Drip irrigation is, by some distance, the most efficient form of agricultural irrigation, but it is also one of the most difficult to maintain. A network of pipes, interwoven with emitters at strategic locations, allow water to be dropped directly onto the root zone of crops with unerring accuracy, so much so, that it can result in a 95% distribution uniformity, which, for the unaware, is a measure of how evenly water soaks into the ground during irrigation.

    Sprinkler irrigation

    Sprinkler irrigation works in much the same way as drip irrigation does, just in a slightly less efficient manner. Water travels from the source, becomes pressurised thanks to a self-priming pump, and is then distributed across crop fields by a selection of sprinklers. If the sprinklers are positioned optimally, and water is applied in a uniform fashion, sprinkler irrigation can be relatively efficient. What makes sprinkler irrigation less efficient than its pressurised cousin drip irrigation, is that it can be thwarted by adverse weather conditions - even a simple breeze can drastically affect the trajectory of water from sprinklers.

  • Things to Consider Before Buying a Hot Tub

    According to the British and Irish Spa and Hot Tub Association, there are 10,000 hot tubs sold in the UK annually. If you are considering adding to that number and taking the plunge yourself, there are a number of things you should know first.

    Deciding between the different types of hot tub

    Negotiating the minefield that is the world of hot tubs is far from a straightforward task. And if you want to make the right decision, you’re going to need to know about the different types of hot tubs. They vary by the external coating that defines their appearance, and the jets that determine the kind of experience they're going to give you. Above-ground hot tubs are considerably cheaper than their in-ground counterparts and have the benefit of being loosely ‘portable’ - they can be moved, but, on average, they still weigh 225 pounds.

    The cheapest and most portable hot tubs are inflatable or made from PVC, and the higher end ones are made from acrylic or wood. The complexities of hot tubs don’t end there though - hot tubs can be differentiated by the labels: whirlpool tub, jacuzzi or indoor spa. Despite the apparent differences, they are all relatively similar. All hot tubs are capable of producing the ‘whirlpool’ action of water, the term indoor spa is pretty much interchangeable with hot tub, and Jacuzzi is a brand name that  has over time become synonymous with the term 'hot tub.'

    Deterring health concerns

    In 2014, Huffington Post ran a horrifying article on hot tubs, bringing to light the plethora of diseases and infections that can get to you via the simmering water and steam of a hot tub. From ‘hot tub rash’ to a potentially fatal respiratory infection called Legionnaire’s Disease, the article certainly pulled no punches. While a single read-through would be enough to put many a potential hot-tub owner off, it did stress how achievable it is to vanquish microbes from the water, and we’re going to do the same here.

    There are a number of signifiers that are indicative of an unsafe hot tub- an odour, sticky or slippery tiles, an absence of the sound of a working filter, and a temperature in excess of 40°C. More subtle warnings are a pH that isn’t between 7.2 and 7.8 and an unbalanced composition of chlorine or bromine - these you can check with a test strip.

    How much will a hot tub set you back?

     

    Initial costs, installation costs and running costs for hot tubs all depend on the type of hot tub you elect to buy. Initial costs can vary from a few hundred pounds for inflatable versions to tens of thousands for an in-ground wooden or acrylic one. Running costs are similarly variable, but not quite to the same extent as initial cost of course. Inflatable hot tubs can be plugged straight into a mains socket but more elaborate hot tubs may require re-calibration when it comes to plumbing, electrical and even gas work.

    Given that hot tubs are essentially kept warm 24/7 whatever the weather, it is fair to say that they can surmount a considerable challenge to the health of your finances. The US Consortium for Energy Efficiency suggests that the running costs of a hot tub typically account for half of a single home’s entire energy use.

    How is your hot tub going to affect the environment?

    Grundfos Magna

    Accordingly, you can imagine that the effect on the environment is equally significant. If you are considering investing in a hot tub that is anything more substantial than an inflatable one, it is also worth  investing in an infrastructure to accommodate it properly - an infrastructure that will minimise your tubs running costs as well as its contribution to global warming. A Grundfos Magna circulator will do both of those.

  • Six things to keep in mind when designing a bathroom

    Designing a new bathroom can be a real headache. More often than not, bathrooms are already one of the smaller sized rooms in the house. When you add showers, sinks and toilets to it, it can make planning your new bathroom very tricky indeed. Juggling these space constraints whilst simultaneously worrying about functionality, visual appeal and durability, can lead to a muddled approach, and a disappointing, sub-par bathroom. To walk you through this process, and point out what you should be prioritising, we have put together this quick guide to designing a new bathroom.

    Functionality

    grundfos pumps uk

    At the end of the day, a bathroom’s functionality is of utmost importance. If your shower doesn’t work and your toilet doesn’t flush, you’re going to run into some problems. With this in mind, you want to be certain that all of your appliances, regardless of appearance, will function the way you need them to. And Grundfos pumps UK are a manufacturer you can rely on. From home booster units that can resolve low water levels to central heating circulators that can single-handedly improve efficiency across an entire system;  Grundfos can help you sculpt a superbly functioning bathroom.

    Durability

    bathroom tiles

    When you are investing money into anything, one of the very first questions you should ask is: how long is it going to last? And this ethos is definitely applicable to bathrooms. While wallpaper might be an attractive short term investment, it is exactly that - short-term - it might be visually appealing, but it won’t last a fraction of the time that tiles will. Tiles are far better suited to tolerate splashes of water and clouds of steam, offering you superior value for money.

    Visual appeal

    brass bathroom

    Your primary concern should always be quality, but that does not mean you need to scrimp on the visual aspect of your bathroom. Brass fittings have experienced a resurgence as of late, mostly because of its warm tones that help to distinguish it from the  cold and clinical looking, albeit popular, chrome and nickel. A distinctive vanity cabinet can have a similarly drastic effect. By acting as the focal point of the bathroom, it can add a healthy amount of character. It is however, vitally important to consider how your own financial and space restrictions can dictate your ability to outfit your bathroom in the exact way you want it to.

    Space

    best floating vanity

    One way of circumventing a space issue is to choose a floating vanity cabinet. Its ability to float far from voids the traditionally elegant nature of the vanity cabinet, and creates space that otherwise would not exist. As well as providing additional storage space, the floating vanity cabinet, more importantly, creates the perception of a larger bathroom. Equally deceptive but effective are large mirrors and glass panels, both of which are adept at creating the illusion of a bigger bathroom.

  • Grundfos Are Lead Supplier to Water Treatment Plant

    Impressive news coming out of Grundfos: they are now lead supplier for the Austrian based Aqua Engineering water treatment plant - further proof of their excellence as a supplier of pump technology.
