VARISCO SELF-PRIMING DIESEL DRIVEN PUMPS

SELF-PRIMING PRINCIPLE

The air is drawn into the pump due to the negative pressure created by the moving impeller and is emulsified with the liquid contained in the pump casing. The air liquid emulsion is forced into the priming chamber where the lighter air is separated and leaves through the discharge pipe; the heavier liquid drops back down into circulation. Once all of the air has been expelled from the suction pipe, the pump is primed and works like a normal centrifugal pump. The pump can also work with an air-liquid mixture. The non-return valve has a dual function: it prevents the suction pipe from emptying when the pump is off; in the event off accidental emptying of the suction pipe, this holds a sufficient amount of liquid in the pump casing to prime the pump. The discharge pipe must be free to expel the air coming from the suction pipe.

J-SERIES

Self-priming centrifugal pumps, ideal for pumping liquids with solids in suspension. They are for applications where the main feature is the difficulty in priming and are used in the industrial, building, and wellpoint plant sector.

ST-R SERIES

Self-priming trash pumps ideal for pumping liquids with large solids in suspension. They are used in purification plants and sewage systems and provide a complete safe management and maintenance.

HBD HIGH HEAD SERIES

High head auto prime assist pumps, are fitted with a high efficiency close vane impeller which can handle water containing sand, mud and solids in suspension. These units are ideal for dewatering projects with a high heads or pumping over
long distances.

Pump Sizes: 40mm - 300mm up to

Solids Capacity: 76mm 5m³/h - 

Flows up to : 1400m³/h

Heads up to : 120m

Models: All VARISCO pump models are available in bare shaft, electrical or diesel driven units.
