Pump overview

ZW type self-priming sewage pump is a new generation pump which is designed and produced according to the pump standard and our experience of of past years production.These pumps’ pipelines do not need to install the valve.Pumps can directly start to work just with quantitative storing liquid inside the pump.no need to add new more liquid.This type pumps simplifying the pump piping system and improve the labor conditions heavily.

Main applications

ZW type self-priming sewage pump is suitable for treatment of municipal waste water,construction projects,hotel,printing&paper dyeing,textile and other places of sewage discharge. it Is an ideal equipment for mud pumping,, waste water, sewage and wastes, paper scraps,and solid particles.including fiber and silt.

 Pump features

1.Advanced mechanical seal and impeller is directly installed into motor shaft.The pump is high efficient,energy saving,compact structure,small size,less weight.convenient installation and maintenance.

2.Pumps can be used for operation in parallel or in series. 

3.Pump mainly includes pump body,mechanical seal and motor(single phase motor or three phase motor).The pump rotor shaft is high quality carbon steel material and with corrosion treatment which makes the shaft with more reliable mechanical strength,wear resistance and corrosion resistance.also make it more easy to take apart the impeller and maintenance.”O”type sealing rings are placed to each fixed rabbets of pump to prevent leakage.

Working conditions

1.The maximum diameter of the medium particle should be less than 60% of the suction pipe diameter of pump.

2.The maximum length of the medium fiber should be less than 5 times of the suction pipe diameter of pump

3.The weight of the impurities no more than 15% of the total medium weight.and the proportion of the medium is no more than 1.2g/cubic centimeter.

4.Please inform us before order if your medium with small particles.we can use the wear resistant mechanical seals for pumps.
