Operating Principle: The Double Disc pump combines the performance features of a positive displacement pump and the principle of "Induced Flow" to provide superior versatility in fluids handling. Based on a "Free Diaphragm" technology, the pump utilizes a unique principle of operation where the discs perform the duties of both diaphragm and valve, providing a double acting, non-clogging, pumping action. Through an arrangement of connecting rods and a camshaft, a reciprocating action of the discs is created, forming a large cavity between the discs. This cavity is filled and exhausted in a continuous flow. The large valve-like discs mean that solids and rags can be handled without loss of pumping action. The valve-like discs have large seating areas that provide for low internal velocities, extending the pump wear life on abrasive sludge and slurries. The fluid chamber is sealed with flexible trunions which eliminates packing's, mechanical seals, and requires no flushing water or other forms of lubrication. The large diameter discs are proven to handle large solids, rags, plastics, etc., that would cause other pumps to fail.
