Product Description

Oerlikon Leybold TW 400/300/25 S Turbovac Cartridge Pump, 800160V0019

The Turbovac Cartridge TW 220/150 S is a dual-inlet and the TW 220/150/15 S and the TW 400/300/25 S (-PP) are triple-inlet wide range turbomolecular pumps designed for mass spectrometers to evacuate up to three vacuum chambers. They have no housing and are designed to be integrated into a system. They are suitable for pumping air and clean gases.

The pump comprises essentially a multi-stage rotor with the stator group, and the drive. The first section of the rotor are two turbomolecular pump stages while the second section represents a Holweck stage. The Holweck pumping stage increases the permissible forevacuum pressure level markedly when compared with the classical turbomolecular pump. The pumps have gas inlets into the turbo stages, the triple-inlet pumps have a third gas inlet into the Holweck stage. The two triple-inlet pumps are very similar, they differ mainly in the Holweck stage and the operating speed.
