Wilden Pumps Selection

Wilden Air Operated Diaphragm Pumps primary types are listed below.

Featured:  Pro-Flo Shift

Wilden’s Pro-Flo SHIFT is part of a new generation of air distribution systems (ADS) that have been designed to eliminate overfilling in AODD pump operation.  This pump design restricts the air flow into the air chamber near the end of each pump stroke so that only enough air is introduced to keep the pumping process going. This is accomplished through the incorporation of an air control spool that automatically optimizes air consumption and eliminates overfilling of the air chamber with no reduction in flow rate. 

Designed off the same basic design principles as the tried and true Pro-Flo Series which feature:

  • Unbalanced spool preventing stalling
  • Simple pilot spool to trigger which air chamber is filled
  • Minimum moving parts (less wear)
  • Tight tolerances to eliminate lost air
  • Up to 60% Air Savings at existing flow rates
  • Reduced total cost of ownership
  • Ease of maintenance
  • Ability to be used in harsh operating environments
  • No electricity required
