Environmental and Operating Characteristics of an Axial Piston Hydraulic Pump 680249

The present generation of hydraulic piston pumps is reaching operational pressures as high as 5000 Δpsi and speeds up to 3600 rpm. These conditions dictate the need for closer control in component and system design, especially when noise levels reach disturbing values and fluid contaminates impair the operation of the carefully machined surfaces needed for optimum system performance. This paper analyzes environmental and operating characteristics inherent in the hydraulic piston pump.
