Operating speed: 1800–2200 rpm (optimal operating range 1900–2000 rpm)

Control method: Load sensitive (LS) + Negative Flow Control/Electro-Proportional Control (DPH/DTH/SH correspond to different control logics, perfectly matching the Caterpillar 349D hydraulic system)

III. Compatible Models and Dedicated Matching Instructions

Core Compatibility: Caterpillar 349D (45-50 ton excavators), also compatible with Caterpillar 345C and 345D models

Dedicated Caterpillar 349D Compatibility: 1:1 interface matching with the original Caterpillar 349D hydraulic system; flange, shaft, and solenoid valve interfaces are completely universal, allowing for direct installation without modification; the control logic perfectly coordinates with the Caterpillar 349D engine (Catepillar C13) power output, ensuring stable pressure and sufficient flow under heavy loads, without stalling or speed drops.

IV. Core Product Features

Utilizing Kawasaki technology, the plunger and cylinder body are made of high-wear-resistant alloy material, offering impact resistance and high-pressure resistance, suitable for high-intensity operation scenarios such as mining and heavy earthmoving with the Caterpillar 349D.

Precise flow output, rapid pressure response, and smooth, uninterrupted compound motion ensure Caterpillar performance.

Factory-tested pressure and flow rates, meeting Caterpillar original factory standards, with a low failure rate and stable warranty.

As a high-performance replacement for the Caterpillar 349D original pump, its price is only 50%-60% of the original imported pump, significantly reducing equipment maintenance costs.
