Liquid Ring Vacuum Pumps
(Single-action Type)

Bore Inlet x Outlet(mm) 150x150 - 300x300
Motor Output(kW) 75 - 340

The VL-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 in belt-drive type with motor output from 75kW to 340kW.
