Ram type pump

A ram type pump for a manure handling system, said pump comprising:

• a hollow, cylindrical pump housing having a transfer portion and an actuator portion, the transfer portion defining an outlet opening and an inlet hopper;
• a cylindrical ram slidably located for reciprocating movement in the housing past the hopper, the ram being adapted to push manure entering the hopper through the transfer portion;
• a releasable coupling connected between said transfer portion and said actuator portion at the juntion thereof, the actuator portion thereby being separable from the transfer portion by releasing said coupling;
• actuator means located in said actuator portion connected between the ram and said actuator portion for reciprocating the ram;
• guide means located in said actuator portion for axial alignment of the ram in the housing;
• and
• a bearing and seal assembly removably mounted in the pump housing adjacent to said releasable coupling, said assembly being concentrically located around the cylindrical ram for sliding, sealing engagement of the ram, thereby preventing manure from entering the housing actuator portion.
