Paper presents the construction and results of experimental research of gerotor pump with gears made of POM and PPS. Research program included verification of design factors (axial and radial clearance), operational factors (impact of speed, pressure and temperature on the pump characteristics) and definition of durability characteristics. Results of research proves that the pump with gears made of plastics can operate at high speeds (up to 4000 rpm), at temperature of the working fluid in the range 25°C – 50°C, with the working pressure at the outlet of the pump 4 MPa. Presented results of long-term tests, shows that the pump with gears made of plastics worked for 40 hours maintaining a constant level of efficiency Q = 12.5 dm3, which represents 80% of the theoretical volumetric efficiency.
