Leybold Vacuum TURBOVAC TW 70 H Turbomolecular Pump - REBUILT

The TURBOVAC models 50 to 1000 are turbomolecular pumps featuring grease-lubricated bearings. These units are engineered to pump vacuum chambers down to pressures in the high-vacuum range. A TURBOTRONIK frequency converter and a forevacuum pump are required for the operation of the TURBOVAC.

These units are not suitable for operation without a fore-vacuum pump.

We offer repair service and are capable of rebuilding, balancing and testing this pump. View our inventory of Leybold Vacuum turbo pumps.

Most Leybold Vacuum TURBOVAC TMP models produce a clean, hydrocarbon free vacuum at an ultimate pressure of <10-10 mbar. Other features of the TMP models include grease lubricated bearings that permit the pump to operate in any desired angular position, while retaining the advantages of single axial flow construction; dynamic balancing of the pump's replaceable rotor/spindle assembly produces silent running with minimal vibration; the turbine and drive assembly with internal motor are mounted in a stainless steel housing; the pump motor is protected from overheating by a thermal switch, which turns off the pump's frequency converter if the pump motor exceeds its safe operating temperature limit; a heat treated aluminum alloy is used for the rotor assembly; the complete drive assembly including bearings and motor is located in the fore vacuum space.
