Overview
The ZW series non clogging sewage pump is an efficient,energy-saving,and non clogging sewagepump developed by combining advanced technology from similar products at home and abroad.Allperformance indicators have reached the technical level of similar products abroad.Due to theuse of unique open impellers and the use of special hard alloy materials for mechanical sealingdynamic and static rings,the entire sealing system fully adopts foreign technology,featuringnon clogging,long sealing life,convenient maintenance,and high efficiency,Highly popularamong users.
Structure Introduction
The ZW series non clogging sewage pump is made of carbon steel and stainless steel to meet thedifferent requirements of users,and can be equipped with explosion-proof motors.The structureconsists of two parts:an electric motor and a water pump.
1.The motor adopts an asynchronous motor,which can be selected as a variable frequency or ex-plosion-proof motor.
2.The water pump is located at the other end of the motor.The impeller of the water pump isopen and has strong drainage force,which is not easy to block.It pumps dirty liquid containingfiber substances and suspended solid particles,with advanced sealing technology and long servicelife.
Application scope
The ZW series non clogging sewage pump is mainly suitable for conveying industrial wastewater andurban domestic sewage.Its biggest advantage is that it has strong self suction capacity,and thesuction pipeline does not need to be equipped with a bottom valve.It can transport sewage con-taining large solid particles,fiber materials,and various impurities,with a solid content ofless than 35%and is not easily clogged.In addition to being suitable for transporting sewage,it can also be used as a drainage pump,pulp pump,filtration and flushing condensate circulationpump,irrigation pump,etc.It is widely used in mines,construction sites,hospitals,hotels,sewage treatment and other occasions.Suitable for medium temperatures ranging from 0 to 150.This series of non clogging sewage pumps is divided into two types:ordinary type and corro-sion-resistant type.The ordinary type material is A3,and the corrosion-resistant type material
is 304,316,316L,etc.Different materials are available for different occasions.
