The Edwards IQDP 80 Dry is a dry vacuum pump. The Edwards IQDP 80 Dry is a four-stage, positive displacement dry pump. The Edwards IQDP 80 Dry has an indirect cooling system and a water-cooled pump motor.[1][2]
The iQDP 80 pump has four stages. The timing gears and adjacent double-row angular contact ball bearings are oil lubricated, but the pumping chambers contain no lubricating fluid. The pump has an indirect cooling system and the motor is water cooled. An optional Gas Module introduces purge gas into the pump. The system can be controlled via a Pump Display Module, an Interface Module, or an iQSingle Pumpset Monitor.[2][1]
When configured with a QMB Roots booster, the booster uses a hydrokinetic fluid-coupling that automatically reduces rotor speed under high gas load and accelerates as the load decreases, allowing continuous operation over the vacuum range without bypass valves.[1]

The ultimate vacuum is 3 x 10^-2 mbar.[1]
No, the pumping chamber has no lubricating or sealing fluid, ensuring a clean vacuum without oil back-migration.[2][1]
The pump can be controlled via an optional Pump Display Module, an Interface Module, or an iQSingle Pumpset Monitor accessory.[1]
