Product Details

Brief introduction:

ZW series self-priming and non-clogging sewage pump is a new structure product which is developed on the base of reaping study of domestic and foreign similar technology.

This kind of pump combines self-priming and non-clogging, adopting axial circumfluence outer-mix type. And through the particular design of case and impeller channel, it not only needn't to be fixed with base valve and poured in water like normal self-priming, but also can suck and discharge liquid containing big grain and long fibrin substance. So it is widely used in municipal sewage project, river and pond breeding light industry, paper-making, weaving, foodstuff, chemical industry, power industry, fibrin, slurry and mixed suspension etc. chemical medium.

Parameters:

Flow rate:	Q= 10~800 (m³/h)
Total head:	H=4.5~10 (m)
Pump speed:	n=1450/2900rpm
Design temperature:	T=-20~200ºC
Fluid s.g.:	γ≤1.24
Pump diameter:	50~350mm

Features:

Pump of this kind has features of simple structure, good self-priming performance and high sewage capability, high efficiency and energy saving, convenient usage and maintenance compared with domestic similar product. And it belongs to the first creation in the country at sewage pump series. All technology and performance indexes are on top of the nation, reaching the international advanced level. So it has wide application market and developing future.

Structure:

ZW series self-priming non-clogging sewage pump consists of pump casing, impeller, back cover, mechanical seal,
pump shaft, bearing seat, inlet valve, air-liquid separate pipe, water valve, inlet and outlet connection pipe etc.

Deposit liquid chamber is designed in pump casing. It and back flow hole upside and circulation hole down connect
working chamber of pump. They become axial circumfluence outer-mix system. Some liquid has deposited inside of
pump when pump stops. When pump starts, the deposit liquid with air throws up out under the effect of impeller. Liquid goes back to working chamber by the gridding of air-liquid separate pipe and air is discharged out of pump. Meanwhile pump casing inside becomes vacuum and it realizes self-priming performance.

Configuration:

Application:

a. Municipal project, sewage project, instruction project.

b. Chemical medium with acid or alkali, slurry.Viscosity≤100centipoise,Solid content≤30%.

c. Sewage transportion in hospital, hotel and so on.

d. Classification of municipal sewage treatment factory and concentrate treatment systems engineering.

e. Transportation of the factory and contaminated water.
