The Edwards E2M40 and Edwards E2M80 pumps are two-stage oil-sealed, high-vacuum pumps designed for reliable, long-term operation in both laboratory and industrial environments. A four-pole three-phase motor provides direct-drive through a flexible coupling. The pumps are free standing mounted on steel runners.
The Edwards E2M80 and E2M40 pumps are two-stage, oil-sealed, sliding-vane vacuum pumps.
Lubrication is provided by a sliding vane oil pump. Oil is drawn into the pump through a wire mesh strainer. The oil is pumped to a spring-loaded distributor valve. The distributor valve directs a lightly-pressurised supply of oil to the main vacuum-pump and by-passes the excess back to the oil reservoir. Some of the excess oil is re-directed through a large area, fine-pore filter and some through a relief-valve. When you switch off an E2M40 or E2M80 pump with the gas ballast control closed, the spring loaded distributor valve provides oil and air suckback protection.
You can inspect the level and condition of oil in the oil box through an oil-level sight-glass. An oil filler-plug is fitted at the top of the oil box. An oil drain-tap is fitted at the bottom of the oil box.
The inlet-port flange is compatible with ISO40 or NW40 fittings. The outlet-port has an NW25 flange.
The gas-ballast control allows you to control the introduction of gas-ballast when pumping high vapour loads.
