    Edwards iQDP80 Claw Type Dry Vacuum Pump Rebuilt Refurbished

    The iQ system

    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.

    The iQDP40 system has an iQDP40 dry pump and the iQDP80 system has an iQDP80 dry pump. The iQ combination systems have an iQDP40 or iQDP80 with a iQMB mechanical booster fitted to the inlet of the iQDP pump. The iQMB pump can be directly mounted on the iQDP inlet or can be mounted in an iQMB booster frame.

    Both the iQDP and iQMB 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: (for example, if you want to use the iQsystem in a different process), you can change the Gas Module.

    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 remainder of this manual describes the use of the Pump Display Module to operate the iQ system: for use of another accessory to operate the iQ system, refer to the instruction manual supplied with the accessory.

    The iQDP pump

    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 contact ball-bearings, are oil lubricated.

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