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

Welch’s BTPro vacuum pump series have a flow and vacuum level to provide fast performance for your size of rotary evaporator, glass reactor, purge oven, or winterization filtration apparatus.

These chemical duty PTFE diaphragm pumps are oil-free. The pumping action and deep vacuum comes from the movement of PTFE diaphragms within PTFE heads. All wetted services in the flow path are made of fluoroplastic, making the BTPro pump highly chemically resistant. As a result, the BTPro vacuum pump series are near-zero maintenance. A cold trap placed in-line with BTPro pump is needed if terpenes are part of the flow path.

Features & Benefits

• High flow for faster processing

• Deep vacuum for higher purity

• Chemically resistant for long service interval

• Oil-free operation for low maintenance
