Water ring pumps are liquid ring positive displacement pumps that use water as the working fluid. They feature a simple structure, reliable operation, easy operation and maintenance, and a wide range of applications.
These pumps are suitable for conveying gases that do not contain solid particles, are insoluble in water, and have a temperature range of -10°C to 60°C.
They are ideal vacuum equipment for vacuum dewatering, vacuum drying, vacuum filtration, and gas compression in industries such as papermaking, tobacco, food processing, textile, metallurgy, coal, and chemical processing.
