This paper presents modifications of the sickle insert (constructional and material) made in a gear pump with internal meshing. The introduced design change consists in making an incision in the sickle insert. Due to this treatment, the races of the insert are pressed against the apex wheels of the gears. The introduced compensation causes a smaller drop in pump efficiency with increasing discharge pressure. The article describes the measuring stand and presents the measurement results. Measurements of the frictional resistance between the material of the gears and the insert material used during the measurements were carried out for the selected parameters of the pump operation. Differences in the frictional resistance were obtained between the POM material used for the sickle insert and the metal pin which reflects the material of the gear. The obtained results confirm that the increased pressure and speed of friction between cooperating elements causes increased frictional resistance, which was confirmed by measurements of torque changes on the pump shaft with the change of discharge pressure and different rotational speeds of the pump. The performed tests will allow to direct the work in order to make an optimal insert that meets the requirements of the constructed (prototype) pump with increased efficiency at higher pumping pressures. This will allow the evelopment of a pump with plastic displacement elements, so that the described pump will be able to be used in the future, inter alia, in the pharmaceutical and food industries.
