Contaminant Sensitivity of Hydraulic Pumps - Development of the ISO/DIS 9632 Test Method

The Author presents the philosophies that led to the development of the test method that allows comparison of different fixed displacement pumps under ‘normal’ operating conditions and ‘failure’ conditions such as, the ingression or generation of large-sized contaminant.

This proposed test method can be completed in one working day and represents the culmination of considerable International effort and co-operation.
