Endurance Pump Test with MIL-PRF-83282 Hydraulic Fluid, Purified with Malabar Purifier
Abstract
The possible deterioration of the fluid during use or the potential for the purifier to remove some of the performance improving additives from the fluid as well as the contaminants was investigated. Endurance aircraft hydraulic pump tests under carefully controlled conditions were previously conducted using hydraulic fluid purified with a rotating-disk and vacuum type purifier, the portable purifier manufactured by Pall Corporation, to assess the potential negative effect the fluid purifier could have on hydraulic fluid performance. In this study, similar tests were conducted with a mist and vacuum type purifier, manufactured by Malabar International. Fluid samples were taken at selected intervals during the pump tests and key physical and chemical properties were determined. Pump tests with both fresh and purified MIL-PRF-83282 hydraulic fluids were successfully completed, and there was no apparent difference in pump performance or in fluid characteristics with either fluid. The mist and vacuum type Malabar purifier is therefore similarly benign to the hydraulic fluid as are the Pall portable purifiers. These Malabar mist and vacuum type purifiers will be integrated into some new hydraulic test stands being procured by the U.S. Air Force.
