Profile: Yamada America, Inc helps companies to solve their liquid transfer problems. We design and manufacture air-operated diaphragm pumps. We utilize the state-of-the-art solid modelling and finite element analysis techniques, including rib and shell methods of injection molding to design non-metallic parts structure. The tubular 304 stainless steel base is designed to simplify rebuilding procedures and to absorb weight distribution. The pumps we offer incorporate bolted construction which eliminates leaks and simplifies reasssembly after maintenance.
