Roots type pumps belong to the group of positive movement pumps. The pistons are driven by a series of gears synchronized with the rotation, guaranteeing free rotation without mechanical friction. Roots type pumps have a wide range of vacuum applications. They are preferably used in combination with a series of pumps (screw pumps, vane pumps, etc.) and are designed for a wide range of vacuum applications.
Nominal pumping speed: from 500 m3/h
Primary user sectors: Lyophilization, chemical processes in a vacuum, evaporation and recovery of solvents, packaging machinery, metallization, metal heat treatments
