<p>A manure transfer pump (19) with a cylinder (28), a piston (30) reciprocable in the cylinder (28), a connecting rod (22) connected to a mid section of the piston (30) and a gate assembly (84) pivotally mounted inside the piston (30) between the axis of the connecting rod connection (110,112) and the rod end of the piston. In operation, the gate assembly (84) swings open during a return stroke and allows manureto pass through the piston (30). On a pumping stroke, the gate assembly (84) closes and manure is forced out the discharge end of the cylinder (28) and sucked in the inlet end at the same time.</p> |
