Learn More --- ## How To Choose Hydraulic Gear Pump? When selecting a hydraulic gear pump, focus on three key parameters: pressure rating, displacement range, and speed range. The pressure rating should be 1.1 to 1.5 times higher than the system’s maximum working pressure to ensure safety. The displacement must meet the maximum flow requirements of your equipment with a 5% to 10% margin. The speed range should align with the pump’s rated speed to guarantee stable long-term operation. Considering these factors together helps you choose a hydraulic gear pump with optimal performance and efficiency.

When selecting hydraulic gear pumps, consider factors such as flow rate, pressure rating, size and weight, material compatibility, and the specific application requirements. It’s also important to evaluate the pump’s efficiency and durability to ensure optimal performance in your machinery. How can I ensure the quality of used hydraulic gear pumps? To ensure the quality of used hydraulic gear pumps, purchase from reputable suppliers who provide detailed inspection reports and warranties. Check for signs of wear, such as leaks or unusual noises, and request maintenance history to assess the pump’s condition before buying. What are the benefits of using rebuilt hydraulic gear pumps? Rebuilt hydraulic gear pumps offer several benefits, including cost savings compared to new parts, improved reliability through thorough inspections and repairs, and a reduced environmental impact by extending the life of existing components. They can be a practical solution for companies seeking effective and economical options. How often should hydraulic gear pumps be serviced or replaced? Hydraulic gear pumps should be regularly serviced based on the manufacturer’s recommendations and operational hours. Typically, routine maintenance is advised every 500 to 1000 hours of operation, while replacement may be necessary every 3 to 5 years or sooner if performance issues arise. ## Who We Serve? ## SANY, XCMG, SDLG, LiuGong, SUNWARD, ZOOMLION, XGMA, LonKing, ...... --- ![](https://www.fairydeerhydraulic.com/wp-content/uploads/2025/05/SANY.jpg) ![](https://www.fairydeerhydraulic.com/wp-content/uploads/2025/05/XCMG.jpg) ![](https://www.fairydeerhydraulic.com/wp-content/uploads/2025/05/SDLG.jpg) ![](https://www.fairydeerhydraulic.com/wp-content/uploads/2025/05/LiuGong.jpg) ![](https://www.fairydeerhydraulic.com/wp-content/uploads/2025/05/SUNWARD.jpg) ![](https://www.fairydeerhydraulic.com/wp-content/uploads/2025/05/ZOOMLION.jpg) ## Are you using the following brands? ## -You can have other choices. ## Caterpillar, Komatsu, Hitachi, Volvo, Kobelco, Doosan, Case, Hyundai, KATO, JCB, ...... --- ![](https://www.fairydeerhydraulic.com/wp-content/uploads/2025/05/CAT-1.png) ![](https://www.fairydeerhydraulic.com/wp-content/uploads/2025/05/Komatsu.png) ![](https://www.fairydeerhydraulic.com/wp-content/uploads/2025/05/Hitachi.png) ![](https://www.fairydeerhydraulic.com/wp-content/uploads/2025/05/Volvo.png) ![](https://www.fairydeerhydraulic.com/wp-content/uploads/2025/05/Kobelco.png) ![](https://www.fairydeerhydraulic.com/wp-content/uploads/2025/05/Doosan.png) ![](https://www.fairydeerhydraulic.com/wp-content/uploads/2025/05/Case.jpg) ![](https://www.fairydeerhydraulic.com/wp-content/uploads/2025/05/Hyundai.png) ![](https://www.fairydeerhydraulic.com/wp-content/uploads/2025/05/KATO.png) --- ### Send us a message If you have any questions or would like to book a session please contact us.
