ZW self-priming Non-Clogging swage pump integrates self-priming and non-jamming blow down, which is unnecessary for mounting the bottom valve and guiding the water like the general self-priming clear water pump and also can pump the filth containing big solid blocks and long fibers, sediment, waste ore, impurities, excrement and all engineering sewage. Therefore, it can alleviate the worker′ s labor intensity completely and also is easy for use, move and installation with seldom maintenance and stable performance .reliable performance, seldom needs maintenance, install easy ,reducing workers′ labor intensity be integrated with self-suction and drainage. It doesn′t need to fix a foot valve or fill inducting water as common clean water self-suction pump. It is international standard and no noise.
ZW series self-priming sewage pumps are with self-priming and sewage discharge. It means the pumps can not only be self-priming as the same as ZX series self-priming pump for clean water without foot valve and pouring water but also suck and discharge the large grain and long fiber and sediment and impurity in the waste water. And the performance is very steady. It is very convenient to operate and move and install and maintain.
1.High quality for sewage: special anti-blocking impeller to make sure pump in good operation and non-blocking.
2.energy-saving&high efficiency: with excellent Wight good Hydraulic model , more 3~5% efficiency compare to normal self priming pump.
3.Good self-priming: it is 1m higher than normal self priming pump and shorter time.
1.environment temperature≤50℃,liquid temperature:≤80℃;special requirement can reach 200℃
2.Liquid PH: Cast iron pump :6～9, Stainless steel :2-13.
4.Self-priming high:4.5-5.5m,pipe length is 10m.
5.Max grain diameter can be 60% of caliber for pump. Length of fiber can be 5 times as caliber for pump.
