Edwards E1M18 Vacuum Pump, Edwards (CAT#: STEM-GLE-0608-LGZ)

The manufacturer of Edwards E1M18 Vacuum Pump is Edwards. Model is E1M18. Each solenoid pump provides 2 x 1 liters of ultragade 19 oil, O-rings and centering rings, two Allen keys and spare drain and filter plug seals. FX Pump Fomblin® made from PFPE needs to be ordered separately. This is a single-stage oil-sealed rotary vane pump that has a pressurized oil system that lubricates the pump shaft bearing surfaces and rotor sealing surfaces. The pump has an oil distribution valve that prevents oil from draining inside the pump after the pump is stopped. The gas-tight pump chamber also prevents backflow unless the gas ballast valve is open. The oil quantity and condition in the oil tank can be checked through the sight glass. The filler plug is installed on the top of the fuel tank. The pump has a drain plug that allows gravity or pressure drain.
