External gear pumps and motors assembled with hydraulic gear pump bushings are widely used in many sectors, such as construction, agriculture, automotive and material and chemical handling equipment.
Built with few components, these reliable, lightweight and robust pumps offer excellent performance in volumetric efficiency. When mounted with low-friction gear pump bushing bearings, they can provide fixed flow efficiencies of more than 95% for hydraulic systems.
