Air Operated Diaphragm Pumps  

Air Operated Diaphragm Pumps

Air operated diaphragms pumps (also known as pneumatic diaphragm pumps, AODD pumps, AOD pumps) are used for endless applications in mining, industrial and general plant service.

Air Operated Double Diaphragm Pumps are especially used where electricity isn’t available, or in explosive or flammable areas. They are also used for chemical transfer, de-watering underground coal mines, food manufacturing or where the liquid being pumped has a high solids content or high viscosity.

The Wilden pumps family of Air Operated Double Diaphragm Pumps has proven its rugged durability and reliable performance in countless installations across the world for decades. As the inventor of the Air Operated Double Diaphragm Pump in 1955, Wilden pumps remain a trustworthy industry leader by pioneering new innovations while providing unparalleled excellence in customer satisfaction.

Allied Pumps is the sole authorised Wilden pump distributor for Western Australia.

  • Wilden Pumps Pro-Flo Shift

    The Pro-Flo® SHIFT is the new standard for Air Operated Diaphragm Pumps. The innovative, yet simple, Pro-Flo® SHIFT Air Distribution System (ADS) features an “air control spool” that automatically optimises air consumption and eliminates the overfilling that can lead to overcharging of the air chamber, all while causing no corresponding reduction in flow rate.

    The Pro-Flo® SHIFT’s revolutionary ADS design meters the air flow, allowing for just enough air to keep the pumping process operational. The results are a reduction in air consumption and operational costs while maximum operational efficiency and volumetric consistency are maintained.

    Now is the perfect time to shift your thinking in Air Operated Diaphragm Pump performance with the “game-changing” Pro-Flo® SHIFT.

  • Wilden Pumps Original Series

    The Wilden pumps Original Series Air Operated Diaphragm pump range was designed for rugged utilitarian type of applications that require a robust design. These pumps ensure reliability without sacrificing ease of maintenance.

    This metal and plastic pump range lends itself to various processes and waste applications. Wilden pumps have the largest material and elastomer offering in the industry to meet your abrasion, temperature and chemical compatibility challenges. Original series pumps are offered in aluminium, stainless steel, ductile iron, polypropylene, PTFE and PFA. A variety of elastomers, connection options and specialised air distribution systems are also available for your specific needs.

  • Wilden Pumps Advanced FIT

    As the global leader in Air Operated Diaphragm bolted pumps, Wilden pumps has introduced the Advanced™ FIT line of Air-Operated Double-Diaphragm (AODD) Pumps that feature superior flow rates and easier installation compared to other brands.

    Advanced FIT Air Operated Diaphragm Pumps offered by Wilden pumps precisely “FIT” bolt-to-bolt and pipe-to-pipe and are specifically designed for maximum performance, efficiency, and containment. The range can be fitted to existing fluid-handling piping systems to provide increased performance with no repiping necessary. They have been engineered to be an easy, cost-effective way to enhance and upgrade existing pump performance.

    Exact FIT from bolt-down footprint to inlet and discharge connection heights with re-engineered fluid path increases flow rates up to 54% versus current Wilden models. With fewer fasteners and easy accessibility with power tools for faster assembly/disassembly and shorter downtime, the latest in Advanced™ FIT technology results in a combination that delivers a complete, cutting-edge Air Operated Diaphragm Pumps-pump solution that is unmatched in the industry.

    Advanced FIT pumps are available in 2” (51mm) and 3” (76mm) sizes with aluminum housings and in 1.5” (38mm), 2” (51mm) and 3” (76mm) sizes with stainless-steel housings. In addition, Advanced FIT pumps are also available with a wide variety of elastomer options for even the most severe applications. A variety of Bolted configuration, connection options and specialised air distribution systems are also available for your specific application needs.
