Liquid Ring Vacuum Pumps

Liquid Ring Vacuum Pumps

Overview

High-efficiency liquid ring vacuum pumps are built for heavy duty, wet and humid applications where most other pumps performance will drop due to abrasion and lime scale from the process. The larger liquid ring pumps are often part of engineered systems designed to meet even the highest demands. Pumps are provided with threaded connections for service liquid, pump draining, vacuum relief valve and companion flanges. Pumps can also come as completely packaged units using water or water as a seal fluid. The proven compression principle allows them to be used in all sectors of industry. Critical applications such as evacuating saturated gases and vapours are easily carried out using liquid ring vacuum pumps.
