Vacuum Pumps

Double-diaphragm Series 2207 vacuum pumps work well in moderately aggressive media for medical suction, sawdust extraction, and mild chemical-mixing applications.

The pumps need no oil and have permanently lubricated bearings and stainless-steel valves. Aluminum components are dichromate-conversion treated. Permanent split-capacitor motors are available for worldwide power sources.
