Product Overview
1.ISG/ISW vertical in-line and horizontal close-coupled centrifugal pumps are designed for clean water and liquids with similar physicochemical characteristics. Typical applications cover industrial and municipal water supply & drainage, high-rise water boosting, garden sprinkler irrigation, fire pressurization, long-distance water conveyance, HVAC chilled/hot water circulation, bathroom hot & cold water pressurization and ancillary equipment matching. Max permissible medium temperature: <80°C.
2.IRG/GRG IRZ vertical in-line and horizontal close-coupled high-temperature hot water circulation pumps are applied for boiler hot water pressurization and circulation in energy, metallurgy, chemical, textile, paper, hotel and hospitality industries, together with municipal district heating systems. Maximum working temperature: IRG <120°C, GRG <240°C.
3.IHG/IHZ vertical in-line and horizontal close-coupled chemical pumps convey solid-free corrosive liquids of water-like viscosity at -20°C ~ 120°C, extensively used in petroleum, chemical, metallurgical, power, paper, food, pharmaceutical and synthetic fiber industries.
4.YG/YZ vertical in-line and horizontal close-coupled oil pumps deliver gasoline, kerosene, diesel and other petroleum products with medium temperature ranging from -20°C to 120°C.
