In any pumping application, friction can spell exponential problems for the entire system. This is especially true for instances where fluid handling focuses on abrasive liquids. However, there is a versatile and reliable solution. The new Samoa UP05 pump combines a universal design with a unique frictionless Pivot-Shaft Air Valve to provide maximum performance and energy efficiency, exceeding market expectations. 

The Pivot Series 1/2-inch air-operated double diaphragm (AODD) pumps are available in metallic and non-metallic materials such as aluminum, stainless steel, polypropylene, conductive polypropylene, conductive acetal, and PVDF with an extensive range of diaphragms, seats, and balls. They offer a wide range of applications and fluid compatibility.


These pumps are very suitable for fluids with the presence of abrasives and their availability in both non-metallic and metallic options expands their versality to meet most any customer’s needs.


The non-metallic options of the Pivot Series include threaded polypropylene, conductive polypropylene, acetal, and PVDF pumps with a wide range of diaphragms, seats, and balls options, which offer broad fluid and application compatibility. End-users will find these pumps suitable for aggressive chemicals with the presence of abrasives.

These pumps offer

  • Superior chemical compatibility.
  • Increased resistance to corrosive fluids and atmospheres.
  • Robust bolted design for longer operation lifetime compared to clamped pumps.


The metallic versions of the Pivot Series are aluminum and stainless-steel pumps with the same wide range of diaphragms, seats, and balls options. These pumps offer a broad fluid and application compatibility that extends to use in the outdoors and general applications with presence of abrasives. Their sturdy construction provides the following benefits:

  • Superior abrasion resistance.
  • Stainless steel versions for increased resistance to corrosive fluids, harsh atmospheres, high tensile, and aggressive temperatures.
  • Very robust design for longer operation lifetime compared to clamped.


Beyond their design options, the Pivot Series pumps also provide users with strong performance features once the job beings, including:

  • Higher efficiency: Maximum fluid flow with reduced air consumption.
  • Increased reliability: No stall, no icing, reliable start-up and longer air valve and diaphragms life.
  • Easy servicing: Simplified maintenance and cleaning. Air valve cartridge easy to replace. The pump is held together by carriage bolts and nuts allowing to accomplish a much faster tear down and rebuild.
  • Compact design: Can be configured to connect a smart pump-controller system to actuate, control, and monitor your pumps.
  • Universal pump: Easy swap-over of main competitive brands.
