Edwards E2M28: 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. 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 suck-back 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.
Please note: Due to shipping regulations, all vacuum pumps will be shipped without pump oil. Oiled vacuum pumps SHOULD NOT be run without oil.
EMF20 Oil Mist Filter:
Mist filters capture oil mist from the outlet of pumps, which would otherwise be ejected into the atmosphere. This may happen when you use gas ballast or when you pump high gas throughputs. You can also return oil trapped in the mist filter back to the pump, although you must ensure that the process gases will not contaminate the pump or pump oil. The EMF20 mist filter can be used on low-pressure applications. They are very efficient at 99.999% DOP test and are also azide proof. The white bottom half of the body is semi-transparent, allowing the oil level to be monitored. The EMF filters have a unique odor element which neutralizes the smell of oil mist.
