Wilden Pumps

Pioneers in Air-Operated Diaphragm Pump Technology.

About Wilden pumps

Wilden is the original inventor of the air-operated double-diaphragm (AODD) pump and remains a global leader in AODD pump technology. Their extensive portfolio delivers robust, efficient pumping solutions across a wide range of industries — from chemical processing and water/wastewater treatment to mining, oil & gas, food & beverage, and general industrial applications.

Pump Ranges & Key Capabilities

Air-Operated Double-Diaphragm (AODD) Pumps
Wilden’s core technology is its AODD pump design — a reciprocating, positive-displacement pump driven by compressed air, using two diaphragms alternately drawing in and discharging fluid. This design provides:

Self-priming — capable of priming itself without external assistance.
Dry-run capability — pumps can run dry without damage, a huge advantage for applications with variable demand or intermittent flow.
Portability & simple installation — minimal moving parts, no complex seals, which reduces maintenance complexity.
Versatility in fluids handled — from low-viscosity liquids to viscous slurries, abrasive or chemically aggressive fluids, and even solids-laden or particulate-containing media.

Wilden offers a broad variety of AODD pump series to match different application needs — from standard to high-pressure, hygienic, or solids-handling models.

Notable Wilden Series & Their Uses

Pro-Flo® Series — the classic AODD pump, long-established and widely used, known for its reliability, ease of maintenance, and suitability for general chemical, oil, and process-fluid transfer tasks.
Pro-Flo® SHIFT Series — an enhanced AODD pump that offers improved air efficiency (reduced air consumption), increased flow rates, and fewer moving parts for greater operational economy and longevity.
High-Pressure Series — for demanding applications requiring higher discharge pressure (e.g. filtration, chemical sludge transfer, solid-laden slurries). These pumps can deliver significantly higher pressures than standard AODD units.
Specialty Pumps (Sanitary / Hygiene, Solids / Slurry Handling, Chemical-Resistant variants) — designed for applications such as food & beverage, pharmaceuticals, waste/wastewater, or abrasive/chemical media, with a wide range of materials and configurations to ensure compatibility and durability.

Wilden also provides a large selection of diaphragm materials, valves, and spare parts — allowing specification to match fluid type, temperature, solids content, and hygiene requirements.
