Edwards EXT 70H Turbo Pump with DN-100 ISO Inlet Flange, KF16 Outlet Flange, 24 V, B72226991, EXT-70, EXT70H, B722-26-991

 

General Overview:

The Edwards EXT 70H, EXT70Hi, EXT250H and EXT250Hi pumps are compound vacuum pumps that combine a turbomolecular pump and a drag pump on a single shaft.

This Edwards EXT70H / B72226991 turbomolecular pump is made from a multi-stage axial-flow turbine which is optimised for operation in molecular flow conditions. The drag pump is made from pumping channels formed by plane rotating disks. The drag pump is designed for operation at higher pressures than conventional turbomolecular pumps.

The light alloy rotor is machined from one piece to form the angled blades of the turbomolecular pump and the disks of the drag pump. The rotor blades rotate between angled stator blades which are supported by spacer rings.

The Edwards Rotor and Stator blades have an open structure at the pump inlet, and a more closed structure at the outlet. This configuration gives an optimum combination of pumping speed and compression when pumping gases of both high and low molecular weight. For the blades to be effective, their speed must be close to the thermal velocity of the gas.

The Rotor of the EXT70H therefore rotates at up to 90000 r min-1, and the rotor of the EXT250H/Hi therefore rotates at up to 60000 r min-1.

Process Gas from the inlet is compressed through each of the bladed stages of the turbomolecular pump and transferred to the drag pump. In the drag pump stages, the gas is further compressed as it is pumped around the channels formed by the separation of the disks. The inlet and outlet of each channel is separated by a close-running seal which diverts the gas through a port to the next channel, or to the pump outlet.

 

EXT 70H DN100ISO-K Technical Data:

  • Inlet Flange, DN100 ISO-K (No Groove)
  • Outlet FLange DN25 KF-F
  • Ultimate Pressure 5 x 10-9 mbar
  • Puming Speed  for N2 65 l/sec
  • Minimum backing pump requirement 0.6 m3h
  • Recomended backing pump  Edwards E2M0.7
  • Nominal Rotational Speed: 90000 r min
It is recommend that wherever possible, you cool the pump by forced-air or water-cooling. You must use water - cooling in any of the following operating conditions:
  • Backing pressure > 10 mbar (1000 Pa) and interstage flow 20sccm (0.3mbar l s-1, 30 Pa l s-1)
  • Backing pressure > 8 mbar (800 Pa) and interstage flow 30sccm (0.5mbar l s-1, 50 Pa l s-1)

Please refer to EXT70 Operating Instructions for more details

The EXT 70H rotating assembly is supported at the inlet end by a frictionless magnetic bearing and by a precision ceramic ball bearing at the outlet end. The ball bearing is lubricated from an oil reservoir and wick mechanism.

It is recomended to use inlet-screen and inlet-strainer protect the pump against damage which would be caused by debris which enters the pump. The inlet-screen also protects you from the sharp blades in the pump.

The EXT pump has a vent-port that you can use to vent the pump and your vacuum system to atmospheric pressure. The vent-port introduces vent gas part way up the pump rotor; this ensures maximum cleanliness. The pump is supplied with a manual vent-valve fitted to the vent-port.

Edwards EXT pump can fited with optional vent-port adaptor and purge restrictor to the purge-port to control the flow rate of the purge gas and to filter the gas supply.
