Welch - 2054 4-Head Chemical Resistant Diaphragm Pump

High Capacity 4-head dry diaphragm vacuum pump

The Welch 2054 is very similar in construction to the 2052, but with higher flow. Welch 2054 is a full chemical-resistant, 4-head, oil-free dry diaphragm vacuum pump with all-PTFE contact surfaces and deep vacuum capability. Oil-Free, portable, full chemical-resistant, means less maintenance and no more frequent and costly oil change, or cross contamination. 3.4 cfm high capacity dry diaphragm vacuum pump with PTFE contact surfaces and deep vacuum with extra high flow. The ideal oil-free vacuum pump for large size vacuum ovens and rotary evaporators (must use foreline trap with vacuum oven).

Vacuum depth and level is not regulated so it recommended to use this pump with a control system such as vacuum manifold with control valve or automatic vacuum controller found here.

These pumps are made in Germany with one year warranty and technical support from Welch Vacuum.
