Heavy-duty excavator hydraulic pump designed for ZX450, ensuring stable pressure output and reliable hydraulic performance in demanding operations.
The YNF18333 hydraulic pump assembly has been developed for the ZX450 excavator, serving as the core power component of the hydraulic system. It is responsible for generating and supplying high-pressure hydraulic oil to drive essential machine functions such as digging, lifting, and rotation.
This hydraulic pump, compatible with part numbers 4432815, 9184686, and 9199338, is designed with a 17-tooth gear structure to ensure accurate power transmission and stable hydraulic performance. The internal components have been manufactured with high-precision machining and durable materials, allowing the pump to operate efficiently under heavy load and continuous working conditions.
The housing and internal structure have been engineered to resist wear, reduce internal leakage, and improve volumetric efficiency. As a result, the pump provides consistent pressure output, helping maintain smooth operation and reducing system failures.
For B2B buyers such as hydraulic system distributors, repair workshops, and excavator maintenance companies, this ZX450 hydraulic pump is a critical spare part. It supports engine-hydraulic integration and ensures long-term machine reliability.
