Chemker 400 Teflon Vacuum Pump — 169400-22

The Chemker 400 is a chemical-resistant, diaphragm vacuum pump which can be widely used to handle acidic, basic and solvent vapors by utilizing corrosion proof PTFE on all wetted surfaces. The Chemker pumps are all equipped with a thermal protection device that automatically stops the pump from running once it is over-heated and allows for resumption after the working temperature cools down. Chemker Series Pumps are chemical duty vacuum pumps that can be used in various applications. All wetted parts are made of PTFE material and the outer case is processed with squeeze-casting aluminum and anti-rust treatment. An air driven diaphragm and oil-free design will lower both cost and maintenance time.
