Kawasaki Precision Machinery is one of the world's largest OEM hydraulic pump suppliers to the excavator industry — and most machine owners never realise it. When you buy a Hitachi ZX200, there's a good chance the pump driving the excavator functions is stamped K3V112DT, not Hitachi. This means the right replacement is a Kawasaki unit — and PumpGrid's refurbished K3V series pumps are the tested, warranted, cost-effective answer.
Machine-to-Pump Cross Reference Guide

| Doosan DX225 / DX255 | K3V112DT | 350 bar | 112 cc/rev | 22-25 tonne |
| Sumitomo SH210 / SH240 | K3V112DT | 350 bar | 112 cc/rev | 21-24 tonne |

| Hitachi ZX330 / ZX350 | K3V180DT | 350 bar | 180 cc/rev | 33-35 tonne |
| Doosan DX380 / DX420 | K5V160 | 350 bar | 160 cc/rev | 38-42 tonne |
| Kobelco SK480 / SK500 | K5V200DPH | 350 bar | 200 cc/rev | 48-50 tonne |

K3V112DT has multiple variants — DT, DTP, DTFJ etc. Confirm from your pump's nameplate before ordering.
How to Identify Your Kawasaki Pump Variant
Find the Nameplate
Look for a metal nameplate stamped or riveted to the pump body — usually on the side or rear face. It will carry the full model number (e.g. K3V112DTP-1R9R-9N2A) and serial number.
Read the Full Model String
The suffix letters after K3V112DT matter: they indicate shaft type, port orientation, and control configuration. "DT" = standard tandem. "DTP" = through-drive variant. "DTFJ" = different flange. These affect fitment directly.
Photograph and WhatsApp
The fastest way — photograph the nameplate and send it to us on WhatsApp. We identify the exact variant within the hour and confirm if we have a match in stock. No guesswork, no wrong part ordered.
Why Kawasaki K3V Refurbishment Delivers Reliable Results
Known Wear Patterns, Precise Fix
The K3V series wears predictably — piston slipper pads, barrel face, and valve plate. Our refurbishment technicians know exactly what to measure and what to replace. There's no guesswork because the failure mode is well-understood.
Variant Verification Before Dispatch
A K3V112DT from a Hitachi ZX200 is not the same as a K3V112DT from a Doosan DX225 — shaft spline and port layout differ. We verify your exact variant from the nameplate photo before any pump leaves our network.
Tested at 350 Bar Under Tandem Load
K3V pumps in excavators operate as tandem units — both pumps running simultaneously under load. We test at rated pressure with both circuits loaded to simulate actual excavator working conditions.
Significant Saving vs Hitachi/Doosan OEM Price
Ordering a K3V112DT through a Hitachi or Doosan dealer often comes with OEM-branded pricing. The same pump, properly refurbished from PumpGrid, costs 40-60% less — because you're paying for the pump, not the badge on the machine it came from.
