Edwards iQDP 40 Dry Vacuum Pump With QMB 250 Vacuum Booster, Semiconductor Pumping System, IQ51-51-004

Edwards iQDP 40 Dry Vacuum Pump With QMB 250 Vacuum Booster, Semiconductor Pumping System, IQ51-51-004

Edwards iQDP 40 Overview:

The iQ system operates at pressures between atmospheric and ultimate vacuum with no lubricating or sealing fluid in the pumping chamber(s). This ensures a clean pumping system without back-migration of oil into the system being evacuated.

Both the iQDP and QMB pumps have enclosed, water-cooled motors. The iQ system is therefore suitable for applications in clean environments where fan cooling is unacceptable.

The iQ system has a Gas Module which introduces purge gas into the iQDP pump. Three types of Gas Module are available, suitable for light, medium and harsh duty processes.

You can manually control the iQ system through an optional Pump Display Module accessory. Alternatively, you can use your process tool or other control equipment to control the operation of the iQ system through an Interface Module accessory, or you can use the iQSingle Pumpset Monitor accessory to control the operation of the iQ system.

The iQDP pump is a four-stage, positive displacement rotary pump in which pairs of intermeshing rotors (of different profiles mounted on common shafts) are held in correct phase relation by a pair of timing-gears. The timing-gears and the adjacent double-row angular contactball-bearings, are oil lubricated.

The pump has an indirect cooling-system and the pump-motor is water cooled.

The QMB pumps are positive displacement Roots vacuum pumps. The pump mechanism is driven by a three-phase electric motor through a hydrokinetic fluid-coupling. The hydrokinetic fluid-coupling is configured so that when the gas-load is high, the rotational speed of the rotors is reduced. As the gas-load decreases, the rotors accelerate to full speed. This allows continuous operation of the pump over the vacuum range without the risk of overloading the motor and removes the need for bypass-valves and associated pipelines.
