Summarize:
1. ISW/ISG water pump is a high-effective energy-saving product designed by YONJOU.
2. Stable running, low noise, high concentricity of components. Bearings of low noise are used for the motor, the impellers are of best dynamic and static balance, no vibration at running and the environment thus being improved.
3. No leakage. The shaft is mechanically sealed with carbide alloy wearable material, settling the serious leakage of the filling seal of a centrifugal pump, extending the duration and ensuring the operation place clean and tidy.
4. Widely used in industrial and cities' water supply and drainage, high buildings' booster water supply, gardens irrigation, fire-fighting booster, remote water supply, warming systems, circular booster of cold&hot water in bath rooms as well as in competitions of equipments.
5. The pump, according to the operation condition of the worksite, may be vertically, horizontally etc. and also according to the requirements for the flow and stroke, mounted in parallel and/or in series to increase the needed flow and stroke.
6. The flow range is 1.1-2400m3/h and the stroke range 8-160m and there are basic type, by-pass type, A B C cutting type etc. And per the different flow medium and temperature, IRG/IRGB/ISWR hot water pump, IHG/IHGB/ISWH chemical pump and YG/YGB/ISWB oil pump etc. Series products. of the same type and same property data have been designed and made.
