The compact design enables simple, fast and economical maintenance.
Design
Liquid ring vacuum pumps are positive displacement compressors, which
are equipped with single or double suction impellers, according to size. Liquid
ring vacuum pumps do not need lubricants; there are no parts in direct
contact inside the hydraulics. Therefore these pumps feature low noise
operation as well as simple and robust design.
