Abstract: A Concrete Pump is a mechanical device comprising of a round funnel shape hoper, pump outlet, rotating pressure and wear plates. Attached to the rotating pressure and wear plates are rotating pump cylinders and opposite the pump cylinders are a rotating wear plate. Pressed against the rotating wear plates is the stationary wear. A hoper outlet and a pump outlet flange are attached to the stationary wear plate. The pump functions as follows: concrete from the hoper passes through the stationary and rotating wear plates into one pump cylinder, at the same time, concrete from another cylinder (previously field with concrete) is pushed through the rotating wear plate and through the stationary wear plate into the pump's outlet. When the pistons reach the end of the cylinders the rotating wear plates and concrete cylinders rotate by 180 degrees and the process is repeated again. The pump is designed so that an entire volume of concrete or similar pumping substance is pumped out of the hoper.
