Product Descriptio

This machine is compatible with the Kawasaki-style hydraulic main pump for Hitachi ZX450 and ZX470 excavators. The entire unit is a high-power dual variable displacement piston pump assembly, serving as the core power unit for 45/47-ton large excavators. The internal friction pairs have been upgraded for high-intensity operations in mining and heavy-duty earthmoving, significantly reducing piston scoring and distributor plate wear caused by prolonged full-load operation, minimizing downtime for maintenance.

1. Flow and pressure are precisely matched to the original engine load, quickly restoring new-machine-level digging power after installation. The bucket digs powerfully, the boom lifts quickly, and travel and rotation are synchronized smoothly. The breaker's continuous striking force remains stable and undiminished.

2. A complete set of seals and solenoid valves are included, with standard installation points. Maintenance and disassembly require no changes to the piping layout or readjustment of the system pressure, significantly shortening maintenance time.

3. The internal core friction pairs utilize a wear-resistant and reinforced process, significantly reducing the rate of after-sales repairs. Each pump comes with a complete sealing kit and electrical control components, and all undergo full-scale testing on a high-pressure bench before shipment.
