“…However , this is clearly an impractical way to develop and screen hydraulic fluids. Therefore, over the years , numerous hydraulic pump tests have been developed [5 ,6,7] now-obsolete Eaton (formerly Vickers) V-104C vane pump [6,7]. Although ASTM D 2882 and related tests have served the industry well for many years, these tests are not sufficient to screen hydraulic fluids that will be used at much higher pressures and under different lubrication conditions encountered in piston pumps.…”

There is currently underway a project, which is being conducted by the ASTM D.02N.07 Piston Pump Task Force , to develop a standard high-pressure piston pump test and related pump testing protocol . Various pump tests are being considered including proposals submitted by Komatsu, Rexroth, Denison, Vickers and others . The objective of this paper is to provide an overview of the importance and current status of this work and to outline future directions this work is likely to take.

Work is currently under way within the ASTM 0.02 N.07 'Hydraulic Fluid Testing' Committee to evaluate the potential of replacing the Vickers V-104C vane pump with a newer, more current model 20VQ5 vane pump for use in an updated ASTM D 2882 standard and other national standards. All the round robin work conducted within the Committee thus far has involved the use of non-aqueous hydraulic oils. Although there are some significant inter-laborato y reproducibility problems, it appears that the overall ranking of these hydraulic oils by most laboratories appears to be consistent. Tofurther evaluate the potential utility of replacing the Vickers V-104C pump with the 20VQ5 pump, a series of different water-glycol hydraulic fluid formulations with significantly diferent wear rates were evaluated using a 'modified' ASTM D 2882 testing procedure. The results showed that expected catastrophic pump failures, which occurred with the V-104C pump, not only did not occur with the 20VQ5 pump, but the relative orders of wear rates for some of the fluids were also different. Keywords pump tests, Vickers vane pump, wear rate, hydraulic fluid, lubrication, standard tests IN TRO DUCT10 NThere are two methods of evaluating the potential lubrication properties of a hydraulic fluid. One method is to conduct a pump test either as part of a laboratory test or as part of a field trial. However, this may be costly and is further complicated by the numerous pump manufacturers, types, models, and, especially, the varying material friction pairings used in the pump design. Over the years, only pump tests based on the Vickers V-104C vane pump, such as ASTM D 2882 and DIC 51 389, have achieved wide acceptability in the fluid power industry.

Work is currently underway within the ASTM D.02 N.07 “Hydraulic Fluid Testing” Committee to evaluate the potential of replacing the Vickers V-104 vane pump with a newer, more current model, 20VQ vane pump for use in an updated ASTM D-2882 and other national standards. All of the round robin work conducted within the committee thus far has involved the use of non-aqueous hydraulic oils. Although there are some significant inter-laboratory reproducibility problems, it appears that the overall ranking of the hydraulic oils by most laboratories appears to be consistent. To further evaluate the potential utility of replacing the Vickers V-104 pump with the 20VQ pump, a series of different water-glycol hydraulic fluid formulations with significantly different wear rates were evaluated using a “modified” ASTM D-2882 testing procedure. The results showed that expected catastrophic pump failures, which occurred with the V-104 pump, not only did not occur with the 20VQ pump, but the relative orders of wear rates for some of the fluids were also different. In this paper, a brief history of the development of the ASTM D- 2882 test, as currently conducted, will be presented, a comparison of the features of the V-104 and 20VQ pump and cartridge assemblies will be given and a comparative tabulation of the pump test using the V-104 pump and the 20VQ pump using different testing conditions will be provided. Finally, recommendations for future work will be made.
