Self Priming Pumps

Self Priming Pumps – Supply, Installation & Servicing

Alton Pump Services offer a range of self priming pumps. Our professional, reliable team supply, install service and repair self priming pumps.

Self priming pumps are designed to clear air and start pumping without intervention. The Self priming pump is able  to retain water after the very first prime.

A self priming pump is a centrifugal pump with external casing that floods the inner pump and uses a mixture of air and water to create a primed pumping state. These pumps stayed primed and are ideal to use for water supply where a suction head is required; they can mix water and air to create a pumpable fluid.

Self priming pumps work by drawing air into the pump by creating low pressure through the movement of the impeller. Liquid is then mixed with the air. This process takes place in the external casing – atmospheric pressure causes the water to be  pushed up the suction pipe, forcing the air in the suction line into the pump. The air will rise and the water will sink – the air free water then flows back into the impeller chamber to mix with more air flowing into the suction line. When all the air has evacuated a vacuum is created forcing water up the suction line to the impeller – this is when pumping commences.  When the pumping beings the water re-circulation will cease.  Re circulation of water within the pump stops when pumping begins.

This type of pump can be used in various applications, which include waste water and chemical uses, water pressure boosting, transfer and spraying fertilisers.
