Edwards E2M0.7 Vacuum Pump, Edwards (CAT#: STEM-GLE-0609-LGZ)

The manufacturer of Edwards E2M0.7 Vacuum Pump is Edwards. Model is E2M0.7. Featuring high ultimate vacuum, fast pumping speeds, quiet operation and the ability to handle steam, the EM Series oil-sealed rotary pumps have become the industry standard for laboratory and light industrial applications. The pump is a self-contained unit, powered by a single-phase or three-phase (four-pole) motor through a flexible coupling.

1. Two-stage oil-sealed rotary vane pump.
2. There is a pressurized oil system to lubricate the pump shaft bearing surfaces and rotor sealing surfaces.
3. Equipped with oil distribution valve to prevent any oil from draining into the pump (suction back) after the pump is stopped.
4. It is equipped with a gas-tight pump chamber so that the oil cannot flow back unless the gas ballast valve is opened.
