The Hepta 200 of Pfeiffer Vacuum is a peak performance dry screw pump with a pumping speed that can reach up to 220 m3/h at 50 Hz and 265 m3/h at 60 Hz. It features a dry screw pump integrated with an intake strainer, a temperature switch in its housing, a silencer, an oil-lubricated, axial face seals, and a non-return valve with an outlet side. It greatly reduced energy consumption with its internal compression, and is applicable for low and medium vacuum applications where oil-free vacuum is needed.
