The first SANDPIPER heavy-duty flap valve air-operated double-diaphragm (AODD) pump was invented by Mr. Warren Rupp in 1968, and by the early 1970s, it had already established itself as the workhorse in meat and poultry processing facilities because of its unique ability to pass large solids that would clog other pumps. In fact, the SANDPIPER heavy-duty flap became known as the animal “blood pump” because it could easily pump the solids that would find their way into the blood collection areas.
