Wilden AODD Pump Technology for Improved Efficiency for Auto Parts Manufacturer

Auto Parts Manufacturer Improved Operational Efficiency with Wilden AODD Pump Technology

How We Reduced the Energy and Replacement Costs for Our Customer

The Challenge:

An Auto Parts Manufacturer in Southern Ontario was experiencing an issue with their existing Air Operated Double Diaphragm (AODD) pumps. The pumps were in use in a number of applications, including lube, oil and waste pumping.

The problem was the nitrile rubber (Buna-N) wetted parts in the existing pumps couldn’t withstand the wear and tear of the applications and were not the best fit. As a result, they were having to repair the existing pumps often—having a significant negative impact on their operations and increasing parts and maintenance costs. They needed a new solution that could handle the workload requirements better and wouldn’t need replacements so quickly and often.

The Solution:

After investigating the applications in detail, our expert Barry Norrish collaborated with the Manufacturer and presented Wilden Pro Flo P2 1” and Wilden Pro Flo Shift PS8 2” AODD pumps with a thermo-plastic wetted package. These pumps with their technology and construction would have a longer life than the Buna-N wetted materials on the existing AODD pumps.  We offered a trial of the P2 1” pumps and the PS8 2” pumps to see how they stacked up compared to the existing AODD pumps.

The advantages of the Wilden Pumps include:

  • Wilden Pro-Flo Shift air spool automatically optimizes air consumption and eliminates overfilling of the air chambers with no reduction in flow rate.
  • Wil-Flex thermoplastic diaphragms can handle abrasion and a broad swing of pH levels, and they have an inherent tensile strength that gives them a longer flex life.
  • The aluminum construction material was a lighter alternative to the cast iron pumps they used previously, which eased the physical strain on the people servicing and maintaining the pumps.
  • Less air is required for operation, translating to significant energy savings per month
  • Fewer components to repair, contributing to savings in replacement costs every month
  • Decreased downtime due to fewer required replacements and the high Mean Time Between Repair (MTBR) of the Wilden pumps

After nine months of having the Wilden pumps in operation alongside the incumbent AODD pumps, the customer still had to order a significant number of incumbent parts. However, the Wilden pumps had zero replacements and zero failures during the entire trial. The customer was so pleased with the performance of the Wilden pumps during the trial that they purchased new Wilden pumps to replace all of their existing AODD pumps.

How Wilden AODD Pumps Work

AODD Pump Technology

Pro-Flo SHIFT Technology

An Air-Operated Double-Diaphragm pump (AODD) is a positive displacement (PD) pump. It has two flexible diaphragms that alternate filling and discharging two pumping chambers as they move. On opposite sides of the filling and discharging chambers, compressed air feeds into and vents from air chambers that create the pumping action.

Because of how the pump operates, it can self-prime, deadhead, and run dry with low shear. This allows it to quickly reach and maintain the desired flow rate throughout an entire production run and withstand the abrasion of the shear-sensitive fluids.
