Product Description

This product is a dual variable displacement piston hydraulic pump assembly specifically designed for the Komatsu PC120-3 old-style 12-ton excavator. It features a one-piece cast structure with both pumps, and the flange mounting dimensions, oil port piping, and regulating valve layout are completely replicated from the original factory standards. No modification is required; it can directly replace the original pump body.

1. It adopts a classic independent variable displacement regulating structure with dual piston cylinders, a hardened alloy distribution plate, and pistons, resisting wear from impurities and suitable for heavy-duty working conditions such as earthmoving, mining, and demolition.

2. It has a built-in constant power control valve group, which can evenly distribute engine power, reducing stalling and speed drops during heavy-duty excavation, and ensuring balanced high and low speed operation.

3. The pump body integrates a pressure compensation valve and a power regulator. Pressure, flow, and combined operation bench testing are performed at the factory, ensuring sufficient digging force and smooth, vibration-free travel, swing, and lifting operations.
