Welch CRVpro

The CRVpro Rotary Vane Vacuum Pump by Welch is an economical starting point for labs looking to reach a deep vacuum level while maintaining varying displacement capacities.

Please contact us for pricing; we carry ALL Welch product variations!

These rotary vane vacuum pumps use DuoSeal Pump Oil to make an air-tight seal, which allows the oil to cool the moving parts. The CRVpro series is competitively priced, but keep in mind that these pumps will require regular maintenance to keep the vacuum pump in proper working order.
