HP G1946-80001 Turbo Pump is Fully Remanufactured and comes with DN100-ISOK Inlet Flange, B74004000, G19468001 for HP 5973 MS


The HP G1946-8001 Turbo Pump was designed for HP 5973 MS

G1946-8001 pumps are compound vacuum pumps that combine a turbomolecular pump and a drag pump on a single shaft.

The HP G19468001 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.

All of the pumps are supplied with an inlet-screen fitted in the bore of the inlet-flange. The HP G1946-80001 pumps are also supplied with an inlet-strainer which fits in the interstage-port. The 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.

All of the pumps have a vent-port 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.

The HP 1946-80001 pump has a purge-port in the motor and bearing housing chamber. In order to protect the bearing lubricant from the effects of high oxygen concentrations, you can introduce an inert purge gas through the purge-port. You can fit an 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.
