RICKMEIER gear pumps in the R6 series are characterized by a simple and robust structure. Optimized flow channels ensure good priming characteristics and quiet running. 

Together with a special design of the tooting and the gear casing, an extremely low noise level is ensured during operation. In particular when pumping foamed oil, a special casing finish ensures additional noise reduction. 

The casings of the standard version are made of grey cast iron, the gear parts of hardened steel. Generously dimensioned, lead-free multicomponent friction bearings have a long service life and very good dry-running properties. 

The shaft seal is designed as standard with a friction-optimized radial shaft seal. In addition, numerous sealing variants are possible.
