Wilden high-pressure pumps

Wilden’s high-pressure air-operated double-diaphragm pumps (AODD) are designed for demanding industrial applications where exceptionally high pressure and reliability are required. High-pressure pumps are especially suitable for filtration, slurry transfer, filter presses, and pumping viscous or solids-laden fluids.

Why choose a Wilden high-pressure pump?

• Extremely high pressure: Up to 20.7 bar (300 psi) without external boosters.
• Simplex and Duplex technology: Pressure amplification of 2:1 or 3:1 compared to supply air pressure.
• Durable construction: Metal body (stainless steel, cast iron, aluminium, Hastelloy).
• Energy efficiency: Pro-Flo® SHIFT air motor reduces air consumption by up to 60%.
• Bolted construction: Maximum tightness and safety.
