CAT330C A8VO200 Hydraulic Main Pump | P/N:216-0038,250-2564 | Guangzhou Xinjiafeng Parts

The Rexroth A8VO200 tandem variable-displacement piston pump is engineered for Cat 330C / 330CL excavators. It features an integrated electronic negative-flow regulator and a pilot pump, delivering power for the boom, arm, bucket, swing, and travel functions. This pump is well-suited for heavy-duty applications such as earthmoving, quarrying, and rock crushing.
We offer brand-new units, reconditioned units, and individual internal components — including cylinder blocks, valve plates, slipper pads, servo pistons, repair kits, and regulator parts — all available from stock.

Our reconditioning process includes complete disassembly, ultrasonic cleaning, inspection of the housing and internal passages, replacement of worn core components — such as seals, bearings, slipper pads, valve plates, cylinder blocks, and servo assemblies — and calibration of the regulator to original factory specifications.
Every unit undergoes full-load bench testing before leaving our facility; test videos and reports are available upon request. Parts are guaranteed to match OEM specifications, ensuring a direct, drop-in fit with identical port configurations and splines — no modifications required.
We provide comprehensive support, including main pump repair, assembly, pressure calibration, and remote technical guidance. We maintain a steady inventory of rotating group components.

We specialize in hydraulic main pumps, swing drives, travel drives, and control valves for excavators.

The hydraulic pump is a critical component in heavy machinery. Regular maintenance extends its service life and ensures normal machine operation. Follow the steps below for proper hydraulic pump maintenance.

1. Check for leaks: Inspect the hydraulic pump regularly for leaks, including pipes, joints, and connections.
2. Replace the filter element: Replace the filter element regularly to ensure the cleanliness of the hydraulic oil.
3. Check the oil: Regularly check oil quality and oil level, and replace or replenish the hydraulic oil in time.
