Comparison
K3V140DTP and K3V180DT: neighbouring classes, different machines
These two sit in the same catalogue family and are often confused when a machine is re-powered or a pump is replaced from an old invoice. The displacement and speed limits are what separate them.
| Property | K3V140DTP | K3V180DT |
|---|---|---|
| Displacement (per pump) | 140 mL/r (per pump) | 180 mL/r (per pump) |
| Rated pressure | 34.3 MPa | 34.3 MPa |
| Peak pressure | 39.2 MPa | 39.2 MPa |
| Max. speed | 2,500 min⁻¹ | 2,300 min⁻¹ |
| Max. self-priming speed | 2,150 min⁻¹ | 1,950 min⁻¹ |
| Max. input torque | 1,120 N·m | 1,120 N·m |
| Application class | 27–33 t hydraulic excavator | 36–40 t hydraulic excavator |

Which one is on your machine
Match the tonnage first
K3V140DTP serves roughly 27-33 t and K3V180DT roughly 36-40 t. Stepping between them changes flow and torque, not just part numbers.
Then the control variant
DTP and DT carry different regulators. The suffix on the nameplate, not the machine model, is what must match.
Check the parts before swapping
Shaft group, cylinder assemblies and valve plates differ between the two. Send the nameplate and we confirm the part lines.
