Liquid Ring Vacuum Pumps
(Single-action Type)

Bore Inlet x Outlet(mm) 40x40 - 200x200
Motor Output(kW) 5.5 - 110

The V-series vacuum pump is a liquid ring vacuum pump of single-action type. It is compactly designed and has minimum operating vibration. Being water used as the seal, there will be no wear, and the performance is unaffected by liquid droplet mixing with intake gas. Available either in motor direct-coupled type or belt-drive type with a wide range of motor output from 5.5kW to 110kW.
