DEVELOPMENT OF A NEW PUMP FILTERABILITY RIG TEST

This paper presents a new method for determining the filterability per formance of hydraulic fluids. The new test method uses an ASTM D 2882 rig. A comparison is made between the new test and two currently-accep ted laboratory bench hydraulic filter tests. The results from tests on ten different fluids are described. Often bench laboratory testing do es not correlate with known field performance. The ultimate purpose of this research is to provide a new filterability screen test that simu lates field performance.
