grease pump / internal-gear / rotary lobe / gerotor

The pump is designed with 2 additional intakes (1 for each direction of rotation) internally located in the pump's body. The pump is typically used to feed a cylinder with inner rod. During the operation of the cylinder, the pump initially takes volume into other chamber. It then takes the content of the tank to compensate the volume difference due to rod. The module features 4 mm inlet and outlet diameter and 15 mm center to center.

The two holes of 4.1 mm diameter are placed at 48 mm (a version with 4 holes is also available) distance to ix the pump to the distributor and/or engine. The pump features 59 mm external diameter and comes in variable height according to flow capacity from 29 to 33 mm. It also features 7 mm diameter shaft with 2.5 mm drive and 20 x 4 mm hub lid diameter.
