Installation and Application
These pumps are self-priming centrifugal pumps, self-priming is achieved 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 recirculated through the ejector, which is connected to the suction piping and eliminate any air pockets, when the pump is started up the water in the pump body circulates through the ejector and transfers any air from the suction to the delivery chamber, expelling it through the delivery piping. At the same time the vacuum generated causes the water to rise in the suction piping.
Since the self-priming system operates continuously, these pumps are practically un affected even by the presence of large amounts of entrained air in the fluid being pumped.
It is always advisable to install a foot valve or non-return valve on the suction opening.
Those pumps should be installed in a covered area, protected against the weather.
