Air-operated double-diaphragm (AODD) pump pumps are versatile workhorses that can even handle aggressive or abrasive fluids as well highly viscous media (e.g. metal slugs). Now Wilden, a leading producer of AODD units, issues a new series of pumps for the plating and metal-finishing industries: The High-Pressure H800 Series.
Wilden states that the H800 has been designed to reliably transfer viscous, solid-laden slurries at high head pressures. Made from ductile iron and stainless steel, they are also available in a duplex design.
According to the company, the duplex design generates a 3:1 pressure ratio of inlet air supply to discharge fluid meaning the pumps have the capability to achieve discharge fluid pressures as high as 17.2 bar (250 psig). H800 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.
