Buy Welch vacuum pumps from MSE Supplies at the best value.

Welch Belt-drive vacuum pumps are known for their ruggedness world-wide in the most demanding applications.

Key features making these pumps so reliable and durable:

•Low pump rpm to reduce frictional wear while minimizing reservoir temperature to lessen chemical activity

•High oil feed to pump models leads to cleanest oil lubricating the internal pump module

•Large oil reservoirs dilute contaminants ingested into the pump Belt-drive vacuum pump are available in three types: DUOSEAL, CHEMSTAR and CAPTURE.

Welch HVAC Vacuum Pumps are used to remove gas, vapors, and other contaminants from refrigeration systems after refrigerant recovery and repair of cooling systems. To ensure the Air Conditioning system is free from contaminants before recharging it with refrigerant, one must maintain a deep and complete vacuum. Our industrial duty HVAC pumps are engineered to deliver deep vacuum for fast evacuation and dehydration. They can pump down quickly reaching 40 microns in hours; not days or weeks like you might experience with a light duty pump.

Welch refrigeration and vacuum pump for HVAC come in two pump styles. DuoSeal® belt-drive vacuum pumps are proven performers with low RPMs and a long service life. Our CRVpro direct-driven vacuum pumps are portable and powerful.

DuoSeal rotary vane vacuum pumps are proven performers with low pump RPM to ensure long service life with durable precision machined steel rotor, cast iron intake, exhaust ring and metal vanes. DuoSeal models are used on the most demanding service applications such as purge pump on absorption chillers and Industrial/commercial chillers. Welch DuoSeal pumps are fitted with components designed to withstand refrigerant contact. Models 1402B-46 and 1397B-46 include integrated handles.
