Liquid Ring Vacuum Pumps
Liquid ring vacuum pumps use an eccentric impeller and a rotating ring of service liquid to form changing chambers that draw in and compress gas.
Product & engineering
Understand the product.
The service liquid seals and cools the chambers. Its temperature and vapour pressure affect achievable suction pressure. Gas-liquid separation and the choice between once-through and recirculated liquid service change the installation around the pump.
What turns activity into demand
A liquid ring pump purchases gas-handling capacity together with a continuing liquid and heat balance. The surrounding circuit changes both operating cost and equipment scope. Keep the pump, separator, heat exchanger and service-liquid circuit distinct. Liquid circulation is not the same measure as extracted gas volume.
The commercial boundary
Keep the pump, separator, heat exchanger and service-liquid circuit distinct. Liquid circulation is not the same measure as extracted gas volume.
