Page 12: Introduction
All of the EH2600 and EH4200 model pumps have an after-cooler in the pump outlet, to reduce the exhaust gas and rotor temperature. The safe area pumps are safe to handle non-flammable gases and vapours within the normal operating parameters of the pumps, as defined in this manual.

The pump bearings, gears and seals are lubricated by oil fed from reservoirs in the hydrokinetic drive/gearbox. A series of seals stops the oil from reaching the vacuum side of the pump. The hydrokinetic drive/gearbox is evacuated. All pumps have ISO inlet A30151880_AA Page 11 11/2020 - ©Edwards Limited... -
Page 15: Principle Of Operation
For ATEX compliant systems using an EH booster pump in combination with an EDP dry pump, the requirements of the ATEX Instruction Manual (see 'Associated publications') must also be met. A30151880_AA Page 12 11/2020 - ©Edwards Limited... - Page 16 If using a non-Edwards backing pump in combination with the EH mechanical booster, please make sure that the volumetric ratio of the backing pump is at least 1/10th of the volumetric capacity of the EH booster.
