This listing is for a brand new Edwards E2M28 high capacity vacuum pump with one year manufacturer warranty from Edwards. Overview The EM range of oil-sealed rotary pumps - renowned for its high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapour - has become the industry standard laboratory and light industrial applications. The E2M28 pump is a two-stage, direct drive, sliding vane pump. The pump is oil sealed and designed for reliable, long-term operation in both laboratory and industrial environments. The pump is a freestanding unit with the drive provided through a flexible coupling by either a single-phase or three-phase (four-pole) motor. Supplied with: Ultragrade 19 oil, NW25 O-ring and centering ring, lifting plate. Fomblin® must be purchased separately for PFPE pumps. Technology The motor is totally enclosed and is cooled by the motor-cooling fan which directs air along the motor fins. The motors are fitted with a thermal overload device. When the motor is too hot, the thermal overload device switches off the pump. The thermal overload device has an automatic reset; when the motor cools down, the device resets and the motor will restart. An oil pressure system lubricates the pump shaft bearing surfaces and rotor sealing faces. The pump has an oil distribution valve which prevents discharge of oil to the pump interior (suckback) after the pump stops. The pumping chambers are air-tight, so this arrangement prevents oil suckback unless the gas ballast valve is open. You can inspect the level and condition of oil in the oil box reservoir through the oil sight-glass. An oil filler-plug is fitted to the top of the oil box. The pump has two oil drain-plugs to allow either gravity oil drain or pressure oil drain. Features and Benefits The pump is designed for reliable, long-term operation. Thermal overload device prevents overheating (single phase only). The pump is a free-standing unit. The drive is provided through a flexible coupling by a single-phase or three-phase (four pole) motor. The motors are totally enclosed and are cooled by the motor-cooling fan. Easy to use controls. Pressure die cast oil box with integral oil seals prevents oil leaks. Gas ballast valve for large water vapour handling capacity. Externally approved to EN61010, CSA, C22.2 and UL61010. Oil distribution valve. Pumping chambers are air-tight. Oil sight-glass, two oil drain-plugs, inlet-port and outlet nozzle all fitted as standard. Gas-ballast control.
