XH220 High-Pressure Pumps

These Wilden Air Operated Pumps feature a unique air distribution system (ADS) that utilises a double-acting power piston and Duplex technology to amplify discharge pressure. Delivering up to 20.7 bar (300 psi), they are ideal for high-pressure applications such as filtration, chemical sludge transfer, and handling viscous, solid-laden slurries.
Features
• Simplex and Duplex technology options (size-dependent)
• The only 3" high-pressure pump in the industry
• Achieves up to 300 psi discharge pressure
• Integrated internal pressure amplifier for a robust design with minimal external piping
