This serie of electric centrifugal self-priming pumps has the characteristics to have the prime made by means of the emulsion air-liquid. The air of the suction piping is sucked inside the pump body by the depression created by the rotating impeller, therefore it emulsifies with the liquid contained into the pump body.


The centrifugal self-priming pumps series JE have been designed to be flanged (or through a flexible coupling) to diesel or gasoline engines and electrical motors.
These groups are then suitable for heavy duty application with solids handling, for this series of pumps are the following:

  • Building industry: Drainage of excavation sites, dewatering of floods. Water transfer to/from tankers.
  • Treatment: Transfer of dirty and sewage waters, emptying of domestic or industrial drain wells.
  • Ship industry: Bilge dewatering, washing, water transfer.
  • Civil industry: Transfer of muddy, chemical liquids with solids and particles in suspension. Fire-fighting. Sewerage system drainage.
  • Agriculture: Irrigation at low and middle pressure head.

The emulsion air-liquid is pushed into the delivery channel where the air, which is lighter, gets separated and gets out from the delivery piping; the liquid, which is heavier, returns into circulation. Once the pump gets rid of all the air from the suction piping, the pump starts and it works as a normal centrifugal pump, therefore the pump can work also with a mixture of air-liquid. There is a non-return valve fitted to the discharge side which enables a small quantity of liquid to be retained in the pump body thus allowing an automatic prime and suction lift to any application. This eliminates the need to prime the pump at each start up.

Pump Construction

  • Pump body, impeller, pump support and inlet in Cast Iron.
  • Non return valve in Nitrile Rubber and Steel.
  • Mechanical seal in Carbon Ceramic (upon request tungsten/carbide).
  • Rotor shaft in Stainless Steel fitted with seal bearings.
  • Totally enclosed fan cooled motor (TEFC).
  • Single phase motors with a built in thermal overload protection on request, the capacitor is permanently in circuit.
  • Winding Insulation to class F.
