The Controlled Comparisons

To create real-world conditions to measure the effectiveness of various ADS technologies industry-wide, a controlled, objective head-tohead test was arranged comparing four of the industry’s top AODD pumps, which were fitted with traditional, electronically controlled and mechanically actuated ADS. Common conditions of service that are seen in the field were replicated in the laboratory.

This simulated application required each pump to produce a flow of 320 liters per minute (L/min) (85 gpm) against a head pressure of 2.1 bar (30 psi). To achieve a fair comparison between these competing pumps, each pump was run at the inlet air pressure needed to meet the common condition of service. Airconsumption data was then recorded.

The Solution

The data gathered in the objective AODD testing showed conclusively that Pump D (Wilden Pro-Flo SHIFT) beat the competition in all three key points of measurement with the lowest air consumption in standard cubic feet per meter (SCFM), the lowest strokes per minute and the highest volume of fluid pumped per SCFM.

Pump D averaged an overall 30 per cent reduction in air consumption compared to Pumps A, B and C. It also managed the largest reduction in air consumption among the four pumps while still managing the best overall volume of fluid moved per stroke, requiring the lowest strokes-per-minute.

The Wilden Pro-Flo Shift Air Distribution

System in Pump D is not just an incremental improvement in ADS technology, but an entirely new way of looking at how pneumatic pumps operate. To combat the phenomenon of overfilling, the pump restricts the air flow into the filling air chamber at the end of the pump’s stroke to minimize the compressed air that is wasted. The result is reduced air consumption while still maintaining maximum operational efficiency and flow rates.
