ZX, ZW Series Non-Clog Self-Priming Pumps

ZX, ZW Series Product Introduction

ZX and ZW are self-priming centrifugal pumps, featuring a compact structure, easy operation, smooth operation, easy maintenance, high efficiency, long lifespan, and strong self-priming capability. There's no need to install a bottom valve in the pipeline; just ensure the pump contains the required amount of liquid before operation. Different liquids can use pumps with various materials for self-priming.

The working principle of ZX and ZW self-priming pumps is that before the pump is started, it is first filled with water inside the pump casing (or water is naturally present in the casing). Once started, the impeller rotates at high speed, causing water in the impeller channels to flow towards the volute. At this point, a vacuum is formed at the inlet, allowing the water inlet check valve to open, and the air in the suction pipe enters the pump, traveling through the impeller channels to the outer edge.
