Huckepack HO 0429 - 0441 F belongs to the Busch product family of proven Huckepack oil-lubricated rotary vane vacuum pumps. You will find more information on advantages, technology, accessories and spare parts, applications as well as a complete product overview on our Huckepack HO series type page. Technical Specifications Huckepack HO is a series of two-stage oil-lubricated rotary vane vacuum pumps. The pump stages are mounted one on top of the other. The upper cylinder, where the compression is lower has a six vane rotor and the lower cylinder has a five vane rotor for a higher compression ratio. The low and high pressure stages contain an eccentrically mounted rotor. 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, compressing the pumped medium and transporting it to the high-pressure second stage, which operates on the same principle. To achieve outstanding running qualities and excellent chamber sealing, the Huckepack series uses fresh oil lubrication.
