Self Priming Pumps
Self-priming pumps are designed to automatically remove air from the suction line and begin pumping without manual priming. They are widely used in applications where suction conditions are inconsistent or where pumps may be installed above the fluid source.
What is a Self-priming Pump?
A self-priming pump is a centrifugal-style pump engineered to evacuate air from the suction pipe and draw liquid into the pump casing automatically. This makes them highly reliable in systems where traditional pumps would struggle to maintain prime.
How it works
- The pump retains liquid in the casing after first use.
- The impeller mixes air and liquid to create a vacuum effect.
- Air is expelled through discharge while liquid recirculates.
- Once air is removed, full pumping operation begins.
Where are Self-priming Pumps Used?
Construction Sites
Dewatering excavations, foundations, and temporary drainage systems.
Wastewater Handling
Managing greywater and lightly contaminated fluids in industrial environments.
Agriculture and Gardening
Irrigation systems, water transfer, and tank emptying applications.
Commercial & Residential Buildings
Boosting water supply and supporting HVAC systems across commercial and residential properties.
How to determine which Self-priming Pump is the one you need?
Flow Rate
Determine the volume of liquid that must be moved per hour.
Head Pressure
Consider vertical lift and system resistance requirements.
Solids Handling
Check whether the pump must handle debris or suspended solids.
Duty Cycle
Match pump design to intermittent or continuous operation needs. Automatic and Manual self-priming pumps are available.
Comparing Types of Self-priming Pumps
Centrifugal Self-priming
Best for clean or lightly contaminated water with high flow rates.
Sewage Pumps
Designed for wastewater and solids handling applications.
Automatic or Manual Pumps
Automatic or manual self-priming options depending on system control requirements.
Electric Self-priming Pumps
Compatible with voltages from 110v to 415v for a wide range of installations.

FAQs
How do I install a Self-priming Pump?
We recommend installation by a qualified professional and always follow manufacturer instructions.
Do self-priming pumps need priming every time?
No, most retain enough liquid in the casing to self-prime after initial setup.
Can they handle dirty water?
Some models can, but always check manufacturer specifications.
What is the maximum suction lift?
Typically around 6–8 metres depending on installation conditions.
How often should a pump be serviced?
Regular inspection is recommended depending on usage and environment.
Troubleshooting your Self-priming Pump
Pump not starting: Electrical issue or power supply fault.
Pump running but no flow: Blockage, airlock, or impeller issue.
Poor performance: Incorrect sizing, wear, or system restriction.
