Unmatched Reliability: PIVOT Series Air Motor Technology

SAMOA Industrial's latest technology in double diaphragm (AODD) Pumps

Air operated diaphragm pumps (AODD pumps) have become an essential piece of equipment in many industries, thanks to their wide compatibility with fluids and convenient operation. These pumps have no electric motors, gearboxes, or rotating shaft seals, instead they rely on compressed air and two diaphragms to transfer and dispense fluids. When selecting the right AODD pump for your application, the air motor technology used is an essential consideration. The type of air motor used can affect the performance, maintenance, and efficiency of the pump, making it crucial to choose wisely.

One of the most important characteristics to look for in an AODD pump’s air motor technology is its design for reliability as AODD Pumps need to operate consistently, even under the most challenging conditions. Any downtime or failure can cause significant disruptions to the operations, leading to loss of productivity and revenue. A reliable air motor should have no sliding spools with attached O-rings, U-cups or Glyd-Rings that can wear out and require frequent replacement.

Another important consideration when selecting an air motor technology is its ability to prevent unexpected stalling of the pump. Many of the AODD pumps on the market are prone to stalling, which can cause safety risks, damage parts, and lead to downtime. The air motor should also run smoothly with dry, dirty, or damp air, with minimal pump vibration and fluid pulsations.

One technology that stands out in the market is the SAMOA Industrial’s PIVOT Series Air Motor. This innovative air distribution system offers a range of advantages over its competition. The PIVOT Series Air Motor Technology incorporates a patented frictionless pivot valve that has only one moving part – a pivoting rod with two sealing pads at each end. This simplicity and lack of sliding parts results in a pump with minimal wear and tear, making it more reliable than other AODD pumps with multiple sliding spools within the air motor.

Air Motors used in competitive AODD pumps often rely on springs or detent rollers in the Air Motor to prevent unexpected stalling of the pump. These components cycle each pump stroke and wear out especially fast when using unconditioned compressed air. Some competitors even have a manual reset button on their pumps to restart it after stalling. The SAMOA PIVOT Series AODD Pump has reliable non-stalling operation with its Smooth Start Shifter (3S). The patented Smooth Start Shifter (3S) actuator only activates the frictionless pivot valve just when needed during low air pressure situations.

AODD pumps tend to suffer from reduced performance when the exhaust air is directed into the air motor spool assembly, leading to icing issues as the exhaust air expands and drops in temperature. Nevertheless, SAMOA PIVOT Series AODD Pumps have extensively large passageways that prevent pump freezing and thus avoid any reduction in pump performance. These pumps ensure reliable and consistent performance with no fear of freezing.

The SAMOA’s PIVOT Series air motor’s fast reciprocating pivot action between pump strokes enables a smoother discharge flow and reduced pump vibration when compared to sliding spool valves found in competitive AODD pumps. SAMOA’s PIVOT Series AODD pumps are also designed with simplicity in mind. Their modular design reduces downtime and simplifies maintenance, with the air valve cartridge is fully accessible and replaceable within a few minutes. The air motor used in the PIVOT Series pumps also has the fewest number of moving parts in the industry, ensuring reliable and efficient operation.

When selecting an AODD pump, it is essential to consider the air motor technology used. The reliability, prevention of stalling, low vibrations, low fluid pulsations and simplicity of maintenance are all significant factors to look for in an AODD pump. SAMOA’s PIVOT Series Air Motor technology stands out from the competition, offering a reliable, low maintenance, and efficient solution for the most demanding pumping applications.
