RICKMEIER gear pumps are characterised by a simple and robust structure. Short, straight flow channels ensure good priming characteristics and quiet running. Together with a special design of the toothing and the gear casing, an extremely low noise level is ensured during operation.

The casings of the standard version are made of grey cast iron, the gear parts of hardened steel.

Generously dimensioned, specially coated multicomponent friction bearings have a long service life and very good dry-running properties.

The shaft seal is designed as standard with a radial shaft seal. In addition, numerous sealing variants are possible (such as a mechanical seal).

Gear pumps are rotary displacement pumps. When the gear shafts turn, the medium enclosed in the space between the teeth is transported from the suction to the pressure side. Then the medium is displaced toward the pressure side by the intermeshing teeth. The transport of the flow medium results in a pressure drop on the suction side of the gear pump. The flow medium compensates for this pressure drop by flowing in, thereby maintaining the feed process. 

This process is the same for both gaseous and liquid media. As a result, the gear pump is capable of priming the suction pipe itself until it is completely filled with liquid flow medium.
