 Agilent G2589-80062 Edwards B753-04-000 turbo pump HPLC Removed from a working Agilent G1946 LC/MSD being removed from service. Pump works as it should with no problems or whining. Agilent G2589-80062 Turbo Pump, DN 100 ISOK Inlet Flange The Agilent G2589-80062 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 helical grooves. 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. The rotor blades rotate between angled stator blades which are supported by spacer rings. The 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 therefore rotates at up to 60000 r min-1. 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 helical grooves. The 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.
