Self-priming pumps for a limited power supply

Petrol and diesel-driven self-priming pumps are ideal when a mains power supply is not available, as the pump can be used independently from an electrical supply. A petrol or diesel self-priming pump can be used for a variety of applications, including:

• Lawns and flowerbed irrigation

• Cleaning floors and patios using a water supply from wells and rivers

• Fill or drain expansion tanks, sumps and wells

What is a self-priming pump?

Self-priming pumps have liquid stored in them at all times so they can generate a vacuum. They can remove and transfer fluids efficiently without needing to be primed before each use.

How does a self-priming pump work?

Self-priming pumps always have fluid recirculating in the pump head, creating a vacuum. This draws fluid in from the suction line, and air is evacuated. The fluid from the suction line fills the void left by the evacuated air, and valves prevent air from re-entering the pump casing so the pump can continue to operate.
