1、 Introduction to ZW type diesel self-priming sewage pump
ZW type diesel self-priming sewage pump is driven by a diesel engine, and the water pump is a horizontal self-priming sewage centrifugal pump. The water pump can self suction without the need for a bottom valve. The water pump unit has a simple structure, reliable operation, long trouble free working time, easy maintenance and use, small size, light weight, high efficiency, large displacement, and high performance. Based on repeated research of similar foreign technologies, it is a novel product with a perfect combination of diesel engine and self-priming pump, which can be controlled manually or automatically.

2、 ZW type diesel self-priming sewage pump is suitable for:
Flood prevention and drainage, emergency rescue construction wastewater
Municipal sewage contains sediment and impurities in accumulated water

3、 The main features of ZW type diesel engine self-priming sewage pump are:
The diesel engine self-priming pump integrates self-priming and non clogging discharge, adopts axial reflux external mixing, and through the unique design of the pump body and impeller flow channel, it can suction and discharge liquids containing large solid particles and long fiber impurities without the need for bottom valves and tank water intake like general self-priming water pumps. It can be widely used for municipal sewage flood control, drought resistance and emergency rescue, as well as the most ideal diesel engine self-priming pump for conveying media such as river pond aquaculture, light industry, papermaking, textile, food, chemical industry, electrical industry, fiber, pulp and mixed suspension.
