Welch BTPro 170 Diaphragm Pump combines advanced vacuum technology with robust construction, ideal for demanding laboratory applications. Discover more  diaphragm pumps in our dedicated category.

Welch's BTpro vacuum pump series has 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 is near-zero maintenance. A cold trap placed in-line with BTpro pump is needed if terpenes are part of the flow path.

A chemically resistant, manual vacuum regulator with stainless steel dial gauge is available for BTpro100 and BTpro170.

Note: Government regulations require Welch to obtain an end-user certificate this product if either used or exported outside of the United States.
