Centrifugal Pump

Summary

The ZX self priming pump is based on the diffuser principle, which means that the priming ability is independent of valves and other mechanical elements as it is the flow of liquid that carries the air. Before first starting the pump, the casing must be filled with liquid. When the pump has been started, the liquid begins to circulate in the pump casing and the impeller channels. Thus, an air-mixed liquid is produced in the outer third of the impeller and a vacuum is created in the suction piece of the impeller and the suction chamber. This vacuum makes the non-return flap valve open, and air is drawn from the suction pipe into the suction chamber. The air-mixed liquid is led through the upper part of pump discharge volute, where the flow velocity is low and the air separates from the liquid. The air escapes through the pressure pipe and the air-separated liquid returns to the periphery of the impeller.

Construction

Advantage

Back-pull-out construction: Convenient formaintenance and troubleshooting.

Daily maintenance can be performed rapidly bycommon tools,saving time and labor;

With only the suction line down in the liquid (thepump shall be filled with water for first start).

Product details

Application range

(1) ZW self-priming pump is suitable for medium with impurities and solid

(2) ZXL direct-connected self-priming pump, which can save space and be more compact.

Application

The series of ZX series self-priming pumps do not need to install a bottom valve, but only need to ensure that there is a quantitative amount of liquid in the pump body . Based on many years of experience in the production of self-priming pumps, we supply a pump series that meets the future demands for economical and reliable pumps. The maximum temperature 80℃, Suitable for marine,industrial and water supply and drainage.
