Description
Operating principle
ZEBRA is the two-stage oil-lubricated rotary vane vacuum pump. Both stages contain an eccentrically mounted rotor, with two vanes each. Due to centrifugal force, each vane slides out and forms a chamber between the vane and the housing. The pumped medium is trapped inside these sickle-shaped chambers. During rotation, the volume of the chamber is constantly reduced. Thereby, the pumped medium is compressed and transported to the second stage, which operates on the same principle. Afterward, the pumped medium is discharged at the outlet. Forced oil lubrication is ensured by an advanced oil circulation pump.ZEBRA RH

Benefits of the ZEBRA RH series
ZEBRA RH two-stage rotary vane vacuum pumps are the proven solution for industrial and analytical applications in the medium vacuum range. These vacuum pumps can be used for example for leak detection, heat treatment, and plasma treatment.
They feature a multi-frequency motor that can be used in every country of the world without any restrictions. The constantly high vacuum level in continuous operation is ensured by forced oil lubrication, perfectly coordinated materials as well as state-of-the-art precision manufacturing. ZEBRA RH vacuum pumps are equipped with a sophisticated oil circulation pump. It ensures outstanding running qualities and excellent chamber sealing. The non-return valve at the exhaust prevents oil from flowing back into the compression chamber after the vacuum pump is switched off.
