As a result of the oil spill in the Gulf of Mexico, Wilden Pump & Engineering says it has seen an increase in orders for its air-operated double-diaphragm (AODD) pumps. Specifically, the pump receiving the most attention is the Wilden Original Series Metal PX8 pumps. The PX8 pumps are designed to provide reliable operation in harsh environments. The PX8 pumps being used in the cleanup efforts in the Gulf of Mexico feature port sizes of 51mm (2”) and have the ability to handle flowrates up to 181 GPM (685 LPM) at working pressures reaching 125 PSI (8.6 bar). Their maximum suction-lift capability is 24.4-feet (7.4m). PX8 pumps are available in aluminum, ductile-iron and stainless-steel construction with non-wetted housings of aluminum and stainless steel. Elastomer options include Buna-N, Viton, EPDM, Neoprene, PTFE and Polyurethane, among others. The pump’s clamped configuration ensures reliability without sacrificing ease of maintenance.
