Our scientific and innovative company integrates research & development, production, and professional service of top-tier hydraulic pumps, motors, valves, and key hydraulic products. Through rigorous innovation and meticulous engineering, our high-pressure replacement pumps achieve seamless exchange and precise mounting matching with original systems. Our series features minimized operational noise, higher volumetric efficiency, and an enhanced service lifespan engineered to withstand harsh working parameters across 70 countries globally.
We operate world-class CNC production equipment, featuring imported vertical and horizontal machining centers, high-precision double-sided grinding systems, and automated testing rigs. Backed by 12 independent testing laboratories, each variable pump undergoes full dynamic testing before shipment to guarantee zero-defect operational output.
Q: How do I identify the correct replacement model?
A: Simply check the metallic Nameplate on your current pump or motor. The critical details we need to ensure an exact physical and technical match are the complete Model Code, Displacement specifications, and Shaft Type.
Q: How does your pricing compare to the original brand?
A: We offer a highly competitive pricing structure. By streamlining raw material procurement and manufacturing without high OEM brand markup fees, we deliver identical high-grade performance while significantly reducing your replacement and equipment maintenance costs.
Q: What is the standard delivery timeline for an order?
A: Small orders or stock items can typically ship out within one week. For standard volume bulk production (such as pump orders within 500 units), the average delivery window is 15 to 30 days, enabling you to coordinate installation deadlines with absolute confidence.
Q: Do you offer technical support for system installation?
A: Yes, absolutely. We provide active technical support for your engineering staff during system integration and initial commissioning. Our expert engineering team is available to help resolve any dynamic alignment, flow fitting, or control matching queries.
Q: What is the warranty period for your replacement hydraulic pumps?
A: All of our manufactured pumps, motors, and hydraulic component accessories come with a comprehensive 1-year product warranty starting directly from the date of shipment from our factory facility.
Q: Are your components fully compatible with original OEM parts?
A: Yes, our variable displacement axial piston pumps are designed to be 100% interchangeable and equivalent. This includes identical mounting flanges, shaft dimensions, port locations, flow limits, and peak operating performance curves.
