Wilden® AODD (Air-Operated Double-Diaphragm) pumps have proven their rugged durability and reliable performance in countless installations across the globe for decades and have incorporated the latest technology to increase productivity, reduce energy and air consumption while simplifying maintenance. Wilden offers the Pro-Flo® and Pro-Flo® SHIFT Series air-operated double-diaphragm (AODD) pumps for use in the dosing and transfer of thin to viscous, clean to particulate-laden fluids in the general industry, oil and gas, chemical processing, food and beverage, military and marine, and water/wastewater markets.
AODD pumps can match the supposed advantages of competing pump technologies because of a number of operational advantages:
- They are appropriate for use with high-viscosity fluids and can handle fluids that range from water-like to medium and very viscous liquids
- They can run dry and strip discharge lines without getting damaged; if the pressures get to be too much, the pump will just stop running, but it won’t break
- They are simple devices and their control relies solely on solenoid operators, pump-cycle counters and surge dampener assemblies
- Their operating costs can be lower when all of the maintenance, accessories and controllers are included, and in many cases their total cost of ownership is lower over their entire operational lifespan when compared to competitive pump styles
