Wilden’s H800 Series High-Pressure Air-Operated Double-Diaphragm (AODD) Pumps are designed to optimize equipment performance in the plating and metal-finishing industries for the production of manufactured durable goods. The pumps have been designed to reliably transfer viscous, solid-laden slurries at high-head pressures. They are constructed of ductile iron and stainless steel and are available in a duplex design. The duplex design generates a 3-to-1-pressure ratio of inlet air supply to discharge fluid with the capability to achieve discharge fluid pressures as high as 17.2 bar (250 PSIG). The pumps are available with wetted housings constructed of either ductile iron or 316 stainless steel, and non-wetted housings (center block and air valve) of aluminum. They can produce flowrates up to 95 GPM (360 LPM), handle solids as large as ½ inch (12.7 mm), and operate at temperatures up to 225 F (107 C). Diaphragm elastomer options include PTFE and Wil-Flex. –wildenpump.com
