| Domestic Pumps - Self Priming Jet Pump c/w Ejector - SAER M Range |
|
 |
|
 |
|
| This series of electric self prime close coupled pumps has the characteristic of the nozzle and venturi being housed in the pump body. The fluid generated by the impeller is passed only in part to the outlet, the remaining fluid is recycled by means of the venturi system which is connected within the pump body. This allows the self prime function. |
|
| At the first starting, it is enough to fill the pump body with the liquid that, circulating through the venturi, transfers the air from the suction to the delivery, ejecting it through the delivery piping. |
|
|
| Therefore the vacuum which is generated makes the liquid go up along the suction piping, allowing the prime function. |
|
| The presence of the venturi system enables these pumps to be insensitive to the presence of air into the pumped liquid. |
