飞机系列自我启动水泵

These pumps are self-priming centrifugal pump suitable for suction from deep wells,self-priming is achieved using anejector,housed in jet body,which can be installed directly on the pum body or more often lowered in awell and connected to the pump body by two pipes.The total delivery produced by the closed centrifugalimpeller is sent only to the delivery opening,the remaining water is recirculated through the ejector,which is connected to the suction chamber where it generates the necessart vacuum to draw up water from the point where the jet body is immersed.the water from the jet body opening mixes in the diffuser with recirculating water from the pump,thus increasing its pressure at the expense of the recirculating water,and is drawn in to the pump through the scution pipe
