High Pressure Wilden® Air-Operated Double-Diaphragm (AODD) Pumps

The Wilden® High Pressure Series of Air-Operated Double-Diaphragm (AODD) pumps are reliably effective in transfering viscous, solid-laden slurries at high discharge pressures. Wilden’s premier simplex and duplex diaphragm and piston-pump technologies powerfully deliver pressures up to 20.7 bar (300 psig) making them perfect for a wide variety of high-pressure duties, including filtration, chemical-sludge transfer and general industrial applications.

Without the need for costly external boosters or amplifiers for most applications, Wilden high-pressure pumps provide maximum performance for the dollar. And with their bolted construction, these pumps offer maximum product containment.
