More Details:

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 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.

APPLICATIONS
General water supply from rivers, streams, dirty water distribution, agricultural applications, building sites, dirty water disposal. The open impeller design allows water with a solid content to pass easily, whether sandy, muddy or particle laden

PUMP CONSTRUCTION
Pump body, impeller, pump support and inlet in cast iron
Non return valve in nitrile rubber and steel
Impeller cast iron
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
