The effect of running-in on the efficiency of a swash plate axial piston pump was investigated by continuous operation. The shaft speed was 1500 rpm and the discharge pressure was 20 MPa. The experimental results showed that running-in slightly decreased the volumetric efficiency, but increased the mechanical efficiency, resulting in an increase in total efficiency. The momentum of the increase in mechanical efficiency was also significant within 0-40 hours of operation. And when the performance curves were obtained, a decrease in the oil temperature difference between the suction and discharge ports due to the running-in effect was observed.
