MS-631 Rotary Vane Pump

The Agilent MS-631 is a high capacity, single stage, oil-sealed rotary vane pump. The MS-631 features an oil recirculation system, an antibackstream valve which prevents system contamination, and carbon composite vanes for extended pump life. Thanks to its low vibration and its air cooling system the MS-631 is an environmentally-friendly alternative to larger industrial pumps with similar speeds but more noise, vibration, and higher cost of ownership.The Frame Less version allows you to couple a Roots Pump directly to the inlet flange eliminating the need for a frame. Our reliable MS-631 pump is used in combination with diffusion HV pumps in a wide range of industry applications including metallurgy, heat treatment, vacuum coating, e-beam welding, LNG transportation.
