Welch 2052 2.3 cfm Full Chemical-Resistant 4-Head Diaphragm Pump

the Welch 2052 chemical-resistant diaphragm pump is the workhorse of the laboratory! The four-head diaphragm pulls a deep, consistent vacuum while the oil-free (dry) design provides clean operation and easy maintenance. Vacuum pump oil savings alone could be over $1000 per year!

Welch pumps are made in Germany, include 3' of 3/8" high quality silicon vacuum tubing, and are backed by a 1-year warranty. 

Maintenance is as easy as allowing the pump to cycle ethanol through itself. Replacement diagrams are also available and an easy job that can be done in house.
