Company profile

SUNRIDA was established in 2015, which is one of the leading manufacturers of hydraulic pumps and motors in China. We are specialized in providing customers with high‑efficient, quiet and long‑lasting hydraulic pumps and motors.

We are a National High‑Tech Enterprise, with a production base of nearly 20,000 m². Our facility includes CNC machining workshops, assembly workshops, a dedicated testing lab and an independent R&D center. We have dozens of engineers focusing on hydraulic pumps, hydraulic motors and integrated electro‑hydraulic hybrid technology. We independently develop and produce key components including housings, pistons and valve plates. Equipped with industry‑leading CNC machines and a full set of professional testing instruments, and certified under ISO9001, we guarantee consistent machining precision and stable product quality.

Our hydraulic pumps and motors have three core advantages:

 1. Premium Raw Materials

Housings and all core internal components are made of HA Grade A raw materials, delivering superior strength and fatigue resistance, minimizing housing cracking and internal wear from the source.

2. High‑precision manufacturing hardware

We are equipped with two ZEISS three‑coordinate measuring machines, high‑precision grinding machines and 5‑axis machining centers. They inspect 3D dimensions and geometric tolerances of key parts, control roundness and cylindricity, reduce internal leakage and extend product service life.

 3. Strict full‑process production & quality control

All components go through automatic deep cleaning and dust‑free assembly. Finished products pass 3D triaxial endurance impact testing to achieve stable performance under heavy‑load and harsh vibrating conditions. Full‑process management guarantees high stability and low failure rate of our products.
