Rugged oil seal pumps for a wide variety of vacuum needs, including Schlenk drying lines, freeze drying, degassing, concentrations, distillations, and more. Pull drive enables low rpm operation by reducing friction, oil temperature, and oil degradation. Its large oil reservoir minimizes contamination effects and extends maintenance intervals.
Starting in 1880, Welch has provided quality vacuum pumps for laboratory, industrial and educational applications. It has now been over a century and today, Welch is a leading manufacturer of vacuum pump products for chemical and biological laboratories, high vacuum manufacturing, and air conditioning/refrigeration.
