Wilden’s mission is to provide the most reliable, easy to maintain, energy-efficient pump system operating at maximum efficiency and minimal possible cost.


Pro-Flo SHIFT

  • Wilden's most efficient ADS on the market
  • Up to 60% savings in air consumption for a cost-saving green footprint
  • More yield per SCFM vs. competitive units
  • Costs 50% less than an electronically-actuated ADS
  • Fewer operating parts for less downtime and simplified maintenance
  • Submersible application option
  • Easy plug-and-play operation
  • Ideal for harsh operating environments, including potentially explosive atmospheres (ATEX-approved)

Pro-Flo X

  • Incredible efficiency and operational flexibility
  • Patented Efficiency Management System (EMS)
  • Precise flow rate control to best suit your application
  • Higher performance, lower operational costs and greater functional flexibility
  • Outperforms other brands even under the harshest conditions
  • Reduced energy consumption, air consumption and maintenance

Pro-Flo

  • Superior reliability and cost savings
  • Excellent energy conservation
  • Maximum mean time between repair (MTBR)
  • Simple yet durable
  • Plastic center block and lube-free operation
  • Extreme flexibility and reliability

Turbo-Flo

  • Long life and easy serviceability
  • No mechanical trip rods, bearings or springs to wear out or repair
  • Cost-effective, economical
  • Portable
  • Submersible applications option
  • Excels in utilitarian-type applications

Accu-Flo

  • Provides critical external pump control for a variable, easy-to-control stroke rate
  • Perfect for exacting applications such as batching
  • Electrical impulses stroke the pump instead of differential pressure
  • Available as NEMA 5, NEMA 7 or ATEX-compliant
  • Variety of voltage options

High Pressure

  • High discharge pressures
  • Utilizes double acting power piston and duplex technology to intensify fluid discharge pressure
  • Crisp Pressure Relief Valve (PRV) to efficiently shift signal
  • Lube-free operation
  • Reduced energy consumption

Wilden’s patent-pending Pro-Flo SHIFT ADS incorporates a unique Air Control Spool that automatically restricts the amount of air going into the pump during the latter part of each stroke, which eliminates over-filling of the air chamber and results in reduced energy consumption. By optimizing air consumption, the Pro-Flo SHIFT lowers energy and operating costs, achieving up to 60% savings over competitive AODD pump technologies.

Available in 38mm (1.5”), 51mm (2”) and 76mm (3”) inlet/outlet sizes, various models of the Pro-FloSHIFT Saniflo FDA pumps will be available for compliance with industry standards, such as FDA CFR 21.177, USP Class VI, 1935/2004/EC, CE and ATEX requirements. Diaphragms will be available in Buna-N, EPDM, PTFE, Saniflex and Wil-Flex.
