ABSTRACT:
A manure transfer pump with a cylinder, a piston reciprocable in the cylinder, a connecting rod connected to a mid section of the piston and a gate assembly pivotally mounted inside the piston between the axis of the connecting rod connection and the rod end of the piston. In operation, the gate assembly swings open during a return stroke and allows manure to pass through the piston. On a pumping stroke, the gate assembly closes and manure is forced out the discharge end of the cylinder and sucked in the inlet end at the same time.
