In this study, long-term tests were conducted to evaluate the effects of wear particles and test dust on the degradation of external gear pump performance. The results of the hydraulic measurement showed that the hydraulic pump tested with wear particles can operate for 624 h with a cleanliness level of 22/21/19 according to the standard ISO 4406. The pump tested with test dust failed after 5.3 min of operation at a cleanliness level of 21/21/21. Thus, accelerated testing of gear pumps can be performed with a reasonable amount of added test dust, which can significantly reduce the time and cost of long-term testing of hydraulic pumps. Wear measurements of volume loss and estimated wear coefficient confirmed the influence of the worn surfaces of the tested pumps on the measured leakage flow. It has been shown that medium test dust effectively accelerate long-term tests of hydraulic gear pumps.
