Comparison
K3V112DTP and K5V140DTP: what actually differs, and which one your machine needs
Both are swash plate axial piston tandem pumps from the same manufacturer family, and both are widely used on 20-33 t excavators. The differences that matter when ordering are displacement, speed limits, torque capacity and the control variant - the table below uses the catalogue figures for the two most commonly requested models.
| Property | K3V112DTP | K5V140DTP |
|---|---|---|
| Displacement (per pump) | 112 mL/r (per pump) | 140 mL/r (per pump) |
| Rated pressure | 34.3 MPa | 34.3 MPa |
| Peak pressure | 39.2 MPa | 39.2 MPa |
| Max. speed | 2,700 min⁻¹ | 2,500 min⁻¹ |
| Max. self-priming speed | 2,360 min⁻¹ | 2,160 min⁻¹ |
| Max. input torque | 588 N·m | 843 N·m |
| PTO max. input torque | 125 N·m | 125 N·m |
| Application class | 20–25 t hydraulic excavator | 27–33 t hydraulic excavator |
| Machine examples | SANY SY215, SANY SY225, Volvo EC210B, Volvo EC210D | SANY SY335, SANY SY365, Volvo EC300D, Doosan DH300-9 |
How to choose
Match the displacement class
112 vs 140 mL/r is the deciding number for flow: it sets cycle speed and digging force at the same engine speed. Never step down a size to save cost on a machine that works at full duty.
Check the control variant
DTP and DTH carry different regulators. The nameplate suffix, not the machine model, decides what will bolt on and control correctly.
Confirm the flange and shaft
Same series, different shaft options. Send the nameplate photo and we confirm shaft, flange and rotation before dispatch.
