Vacuum Pumps

Series 2119V diaphragm vacuum pumps have been specifically engineered to provide long service in Class-B steam autoclaves.


A combination of engineeredresin and die-cast-aluminum construction provides maximum durability. All wetted aluminum parts are epoxy coated for corrosion protection. Umbrella valves and diaphragm are constructed of EPDM, which offers resistance to steam and water. Thermally protected motors are available for 115-Vac 60-Hz or 230-Vac 50/60-Hz power supplies. The pumps provide up to 27-in.-Hg (932-mbar) vacuum. Maximum flow is rated at 0.81 cfm (22.8 lpm).
