Edwards Exhaust Nozzle for E2M28/30 Wet Pumps, A259-08-146 / A25908146
Edwards Exhaust Nozzle / A259-08-146 Overview:
The E2M28 / 30 A259-08-146 Exhaust Nozzle 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 free-standing unit. The drive is provided through a flexible coupling by a single-phase or three-phase (four pole) motor.
The Edwards E2M28 / 30 electric motor are totally enclosed and are cooled by the motor-cooling fan which directs air along the motor fins.
The single-phase motors have a thermal overload device. When the E2M28 / 30 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. The single phase motors have an on/off switch.
Edwards E2M28 / 30 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 air 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 an oil drain-plug to allow gravity oil drain.
The pump has an inlet-port, outlet nozzle and gas-ballast control. The pump is mounted on an aluminum alloy baseplate on rubber pads.
Edwards Exhaust Nozzle includes the following parts:
- Dimension Length: 1.99 in
- Dimension Inner Diameter: 0.374 in
- Dimension Outer Diameter: 1.52 in
- Material Type: Nylon 6
