Wilden Original(TM) Series AODD Pumps Designed for Harsh Semiconductor-Manufacturing Applications

Grand Terrace, CA - June 17, 2009 - Wilden, the worldwide leader in air-operated double-diaphragm pump technology and an operating company within Dover Corporation's Pump Solutions Group (PSG(TM)), announced today that its Original(TM) Series air-operated double-diaphragm (AODD) metal pumps have several designed-in features that make them one of the best solutions for handling ferric oxide at high temperatures in semiconductor-manufacturing applications.

The Original(TM) Series pump utilizes PVDF, along with Nordel® elastomers, in its construction, eliminating the diaphragm failures, deforming polypropylene wetted paths and other operational inefficiencies that can occur in competitive models. This is a crucial consideration when handling ferric oxide in temperatures ranging from 70°C to 90°C (158°F to 194°F).

The Original(TM) Series pumps also feature Wilden's patent-pending Pro-Flo X(TM) air distribution system (ADS), which offers operational flexibility in semiconductor manufacture. This flexibility is accomplished by the state-of-the-art Efficiency Management System (EMS(TM)), which optimizes the Pro-Flo X(TM) ADS for the actual operation parameters regardless of the application demands or pump size. The EMS(TM) allows the operator to use an integrated control dial to select the efficiency point and flow rate that best suits the application. The Pro-Flo X(TM) with EMS(TM) provides semiconductor manufacturers with the most efficient sump-pump solutions available.

Jim Wilden, founder of Wilden Pump and Engineering Co., revolutionized the pumping industry when he invented the air-operated double-diaphragm pump in 1955. Since then, Wilden has created a line of distinctive pumps that have proven to be trustworthy solutions to pumping applications in a wide variety of industries. Wilden-headquartered in Grand Terrace, California, USA-is a member of Dover Corporation's Pump Solutions Group (PSG(TM)).
