VSP Series Dry Screw Vacuum Pumps
The VSP series of pumps are 100% oil-less rotary screw vacuum pumps. They are designed to operate on a continuous basis at any point from atmospheric pressure to a vacuum level of 0.075 mm Hg (29.9″Hg +). The oil-less pumps are ideal for applications where oil or water sealed pumps are objectionable. The pump comes complete with inlet check valve, gas purge connections & FFKM (generic Kalrez) mechanical seals. .
Applications include chemical and pharmaceutical processing, solvent reclamation, dehydration and crystallization.
Optional Accessories: Explosion-proof motors, booster packages.
