Localized cavitation in high pressure hydraulic pumps can be a critical fault leading to localized cavitation damage which severely impacts the performance and durability of the pump. PumpLinx is able to address this problem using its integrated cavitation module. The tool has been shown to accurately predict the cause of cavitation. This induces the validated prediction of pitting in a high pressure axial piston pump currently being developed by a leading European Hydraulics company. By identifying gap leakage coupled with the timing plate design as the cause of localized cavitation damage, PumpLinx has enable the design engineers to better understand the problem and propose design improvements.

PumpLinx is enabling the automotive industry to reduce the noise emissions for their automobile oil pumps. In the case of one manufacturer, designers were able to reduce the noise for a production line oil pump by over 30 decibels. That is similar to dropping from normal conversation down to a whisper, and, after all, who wants their car oil pump talking above a whisper? This dramatic reduction was accomplished by using PumpLinx to identify the source of pressure ripples causing unnecessary noise. Once the sources were identify, design engineers were able to eliminate the cause and silence the chatter. The result is a quieter, more efficient pump.

Ford Motor Company ATEO is successfully applying PumpLinx for transmission oil pump design.
