Product Description

Self-Priming Centrifugal Pumps
Single Cylinder Water Pump/Single Cylinder diesel Water Pump

1. Overview:
ZW series Single Cylinder Water Pump is a new structure product which is developed on base of reaping study of domestic and foreign similar technology. 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 etc 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 the wide application market and developing future.

2. Application:
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 contain-ing big grain and long fibrin substance. So it is widely used in municipal sewage project, river and pond breeding, light industry, papermaking, weaving, foodstuff, chemical industry, power industry, fibrin, slurry and mixed suspension etc chemical medium.
Operating condition:
1. Surrounding temperature <50degree, Medium temperature<80 degree
2. Medium consistency should not exceed 1240kg/m. 3
3. Self priming height should not exceed the stated number of 4.5-5.5meters, and the suction pipe should not be over 10 meters long.
4. It can pass the suspended grain whose diameter is 60 percent of pump caliber, and the fibrin which is 5 times long of pump caliber.
5. PH range of liquid: 6-9 (For cast iron pump), 2-13 (For stainless steel pump)

Brief introduction:
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 contain-ing big grain and long fibrin substance. It has features of simple structure, good self priming performa-nce and high sewage capability, high efficiency and energy saving, convenient usage and maintenance etc compared with domestic similar product. And it belongs to the first creation in the country at sewage pump series. It can well match diesel engine to improve the working efficiency greatly.
Structure:
ZW series self priming non-clogging sewage pump consists of pump body, impeller, back cover, me-chanical seal, pump shaft, bearing seat, inlet valve, air-liquid separate pipe, water valve, inlet and outlet connection pipe etc.

Single Cylinder Water Pump Working principle:
Deposit liquid chamber is designed in pump body. 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 body inside becomes vacuum and it realizes self priming performance.
