ZWL close coupling sewage self-priming pump

ZWL direct-coupled sewage self-priming pump is developed by our company on the basis of ZW shaft coupling self-priming sewage pump. ZWL self-priming pump is a simple installation of ZW self-priming pump and eliminates shaft coupling. Impeller of ZWL close coupling self-priming sewage pump directly connects the motor shaft, thus reducing the occupied area and making it more suitable for the installation and use of pump room.

ZWL close coupling sewage self-priming pump adopts the axial backflow external mixing type. The pump body and impeller passage have the unique design. ZWL pump has the self-priming performance and non-blocking sewage drainage. It can be like the general self-priming clean water pump without the installation of bottom valve and irrigation water, but also liquid suction and discharge containing large particles, solid and long fiber etc. impurities.

Features:

ZWL close coupling sewage self-priming pump has the characteristics of simple structure, good self-priming performance, strong sewage discharge capacity, high efficiency and energy saving, easy to use and maintain.

Model description:

For example: ZWL80-65-25-7.5

ZW- Sewage self-priming pump

L- close coupling

80- pump inlet diameter (80mm)

65- flow rate (60m3/h)

25- rated head (25m)

7.5- motor power (7.5KW)

Scope of Application

ZWL close coupling sewage self-priming pump is mainly for conveying general sewage and wastewater with larger particles impurities, long fiber. It can be widely used in municipal drainage project, studied the breeding, light industry, papermaking, textile, food, chemical industry, electric power, pulp and mixed suspension of chemical medium such as transportation, industrial wastewater treatment, etc. It is the ideal impurity pump, solid liquid pump, sewage pump.
