This series of water pumps is primarily a self-priming jet pump. Self-priming is achieved using an ejector housed in the pump body. The entire water amount produced by the closed centrifugal impeller is sent only partway to the delivery opening, and the rest of the water is re-circulated through the ejector, which is connected to the suction chamber and generates the necessary vacuum to self-prime the pump. When first starting the self-priming pump, fill the pump body with water without filling the suction of the piping, and eliminate any air from the area between the suction and the delivery chamber by forcing it out through the delivery piping. At the same time, the vacuum that is created causes water to rise in the suction piping, which self-primes the pump.

As the self-priming system operates continuously, these pumps are generally unaffected by the presence of large amounts of entrained air in the fluid being pumped. They are designed as an automatic control system with a booster, pressure switch and gauges.
