Pressure Boosting Pumps
Pressure boosting pumps raise water pressure for buildings, processes, and irrigation systems where the available supply falls short of requirements. From compact domestic boosters to commercial multistage sets, correct selection delivers consistent pressure at every outlet.
What is a Pressure Boosting Pump?
A pressure boosting pump increases the pressure of water flowing through it, either as a standalone automatic pump or as part of a multi-pump booster set. Multistage designs stack impellers to generate high pressures efficiently from a compact footprint.
How it works
- Water enters the pump from the tank, break tank, or supply pipework.
- One or more impeller stages progressively raise the water pressure.
- An integrated or external controller matches operation to demand.
- Boosted water delivers consistent pressure to outlets and equipment.
Where are Pressure Boosting Pumps Used?
Residential Boosting
Homes and apartments with inadequate supply pressure.
Commercial Buildings
Offices, hotels, and retail requiring stable pressure.
Industrial Processes
Feed pressure for equipment, washing, and production.
Irrigation Systems
Driving sprinklers and drip networks at design pressure.
How to determine which Pressure Boosting Pump is the one you need?
Required Pressure
Determine outlet pressure plus static lift and friction losses.
Flow Demand
Size for realistic simultaneous demand, not the sum of every outlet.
Control Method
Pressure switch, flow controller, or variable speed drive.
Construction
Stainless steel hydraulics suit potable and long-life duties.
Comparing Types of Pressure Boosting Pumps
Automatic Booster Pumps
Self-contained pumps with integrated flow/pressure control.
Horizontal Multistage Pumps
Compact high pressure pumps for boosting duties.
Vertical Multistage Pumps
Space-saving high pressure pumps for commercial systems.
Variable Speed Boosters
Inverter-driven pumps holding precise constant pressure.

FAQs
What pressure should I boost to?
Domestic systems typically target 2 to 3 bar at outlets, while commercial and process requirements vary; excessive pressure wastes energy and stresses pipework.
What is a multistage pump?
A pump with several impellers in series, each adding pressure, enabling high heads from a compact, efficient unit.
Do I need a pressure vessel with my booster pump?
A small accumulator vessel reduces pump cycling on minor demands and smooths pressure delivery.
Variable speed or fixed speed?
Variable speed pumps hold constant pressure regardless of demand and reduce energy use, ideal where demand varies widely.
Can boosting pumps run dry?
No; dry running damages seals. Choose models with integral dry-run protection or fit external protection.
Troubleshooting your Pressure Boosting Pump
Pressure below setpoint: Check for closed valves, blocked strainers, or demand exceeding pump capacity.
Pump cycling rapidly: Investigate small leaks and verify the accumulator vessel pre-charge.
Dry-run trips: Confirm supply availability and the condition of any suction-side filters.
