Used Lab Equipment

Features:

The Edwards E2M1.5 is a two stage oil sealed rotary vane pump which has a pressurized oil system that lubricates the pump shaft bearing surfaces and rotor sealing faces. This pump has an oil distribution valve that prevents any oil discharge to the pump interior(suckback) after the pump stops. It is equipped with air-tight pumping chambers, which prevents oil suckback unless the gas ballast valve is open.
