Provisional entry — research in progress
This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
The Pfeiffer TPU 050 Vacuum is a turbomolecular vacuum pump. The Pfeiffer TPU 050 Vacuum uses a DN 63 CF inlet flange and a DN 16 KF outlet flange. The Pfeiffer TPU 050 Vacuum is specified with a nitrogen pumping speed of 50 l/s.[1][2][3]
What it is
The Pfeiffer TPU 050 is a turbomolecular drag pump with a CF flange inlet (DN 63 CF) and a KF outlet (DN 16 KF). The pump uses a wear-free permanent magnetic bearing on the high-vacuum side and an oil-lubricated ceramic bearing on the backing side.[1]
How it works
The Pfeiffer TPU 050 has a rated rotational speed of 90000 rpm. The pump employs a wear-free permanent magnetic bearing at the high vacuum side, which eliminates contact and wear, and an oil-lubricated ceramic bearing at the backing side. The pump is cooled by convection or water, with a water cooling requirement of 15 l/h.[1]
Applications
The Pfeiffer TPU 050 is used in a variety of applications including freeze drying, degassing, casting, dry vacuum smelting of super-pure metals, incandescent lamp manufacturing, electronic tube production, thin film deposition, space simulation, cryogenic research, electron microscopy, nuclear physics, plasma physics, high energy physics, and particle accelerators.[1]
