Features and Benefits

Wilden® High-Pressure Series Air-Operated Double-Diaphragm (AODD) Metal Pumps are equipped with a specialty air distribution system (ADS) that utilizes a double-acting power piston and Duplex technology to intensify fluid discharge pressure. Wilden high-pressure pumps reliably deliver the pressure performance of up to 20.7 bar (300 psi), making them perfect for a wide variety of high-pressure duties, including filtration, chemical sludge transfer and other viscous, solid-laden slurries.
  • Simplex and Duplex technology available (depending on size)
  • Industry's only 3" high-pressure pump
  • Builds up to 300 psi discharge pressure
  • Built-in internal pressure amplifier with limited external piping for more robust design
