KNF's N0150TTI double diaphragm pump

KNF's double diaphragm vacuum pumps and compressors provide greatly increased safety when pumping hazardous or expensive gases. They are especially suitable where safety and gas tightness are essential, e.g., with toxic, radioactive or rare gases. They consist of two diaphragms, a working diaphragm, and an additional backup diaphragm beneath, that is not exposed to the pumped medium or dynamic stresses. The volume between the diaphragms can be monitored for alarm purposes. These pumps are available in a variety of motors, materials and configurations. Contact KNF for further details.
