SZ and SZJ Series Vacuum Pumps and Compressors

SZ and SZJ Series Vacuum Pumps and Compressors

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.

Applications and Features:
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.
