PERIPHERAL SELF-PRIMING PUMPS QW-ZB65T

For domestic pumping clean water

For distributing water in cobination with small pressure sets 

For irrigating gardens

For drawing water from tanks or wells

The pump is provided with a check flap valve on the intake so that it is no longer necessary to fit a foot valves.

The pumps must be installed in enclosed places, or at least protected against inclement weather.

These pumps are mostly self-priming is achieved by using an ejector housed in the pump body. 

The total delivery produced by the closed centrifugal impeller is sent only partly to the delivery opening,

 the remaining water is re-circulated through the ejector, which is connected to the suction chamber and

 generates the necessary vacuum to self-priming the pump, when first starting the pump, 

fill the pump body with water without bothering to fill the suction the piping and eliminiated 

any air from the suction to the delivery chamber, expelling it through the delivery piping. 

At the same time, the vacuum thus generated causes water to rise in the suction piping, thus self-priming the pump.

Since the self-priming system operates continuously, these pumps are practically unaffected enen 

by the presence of large amounts of entrained air in the fluid being pumped, 

they auto-control system with booster pressure switch and gages.
