Summary:
1. ISW/ISG water pump is an energy-efficient product developed by YONJOU.
2. It operates smoothly with low noise and high concentricity. The motor uses low-noise bearings, while the impellers are dynamically and statically balanced to ensure no vibration, thus improving the working environment.
3. This pump is leakage-free, featuring a mechanical seal made from carbide alloy, which prevents serious leakage issues in centrifugal pumps, extends service life, and ensures a clean and tidy operation area.
4. Widely used in industrial and urban water supply and drainage systems, booster water supply for high-rise buildings, garden irrigation, fire-fighting systems, remote water supply, heating systems, and cold/hot water circulation in bathrooms, as well as in equipment applications.
5. Depending on site conditions, the pump can be installed vertically, horizontally, or in parallel/series to meet flow and pressure requirements.
6. The flow range is 1.1-2400 m³/h, and the head range is 8-160 m. There are various types such as basic, bypass, and A/B/C cut types. For different media and temperatures, IRG/IRGB/ISWR hot water pumps, IHG/IHGB/ISWH chemical pumps, and YG/YGB/ISWB oil pumps are available.
