Doosan (now part of Hyundai Doosan Infracore), a major South Korean equipment manufacturer, runs its DX-series excavators — DX140, DX225, DX255, DX300 — on Kawasaki K3V, K5V, and K7V axial piston main pumps, the same hydraulics family used across Komatsu, JCB, and Hitachi excavators. Smaller DX models sometimes use Tong Myung T5 pumps instead. Because exact model designation varies by size class, confirming your machine's pump family from the nameplate matters before ordering.

Our Doosan Pump Quality Standards
Kawasaki-Grade Refurbishment
Most DX-series Doosan excavators run genuine Kawasaki K3V/K5V/K7V main pumps. We refurbish to Kawasaki's original tolerances, verified against your exact model.
Written Test Report
Every Doosan pump leaves our network with a written quality report showing actual pressure and flow readings — verified on a test bench, not estimated.
3-Month Warranty
Minimum 3-month warranty on all refurbished Doosan pumps. If a pump fails due to a refurbishment defect within this period, we arrange a replacement — direct WhatsApp coordination.
Model-Verified Sourcing
Doosan's pump family varies by DX model size class — we confirm your exact machine's pump designation from the nameplate before quoting, avoiding mismatched orders.
