Working Principle
Swash-plate axial piston layout
01
Shaft rotation
→ Cylinder block rotation
→ Piston reciprocating motion
→ Oil suction / oil discharge
02
Swash-plate angle
→ Piston stroke
→ Output flow
03
Larger angle
→ Larger stroke
→ Higher flow
04
Smaller angle
→ Shorter stroke
→ Lower flow
For variable-flow hydraulic systems
For load-changing duty
Model Range
K3V112S
Single-pump format. Straight choice when one main pump section is enough.
K3V112DT
Tandem double-pump layout.
K3V112DP
Parallel double-pump arrangement. Better for some machine layouts.
K3V112DTP
Tandem layout with additional drive-related configuration.
The published 112-size range in the K3V family includes these layout formats.
Applications & Industries
Most K3V112 come from the mobile equipment side, not from light-duty shop hydraulics. This series belongs more naturally on machines that work outside, carry load, dig, move, lift, or cycle under changing pressure.
Earthmoving Equipment
A common fit for open-circuit hydraulic systems on construction machines.
Construction Machinery
Used where the pump has to handle changing load and long work cycles.
Mobile Hydraulic Power Systems
Suitable for main pump duty in equipment that cannot rely on simple fixed-flow output.
Material Handling Equipment
Can also be considered for machines that need strong hydraulic response and repeat operation.
Road and Site Machinery
A workable choice where compactness and hydraulic output both matter.
Mining Equipment
Underground loaders, drill rigs, continuous miners,Compact installation, shock-resistant closed-loop systems

FAQ
Q: What kind of pump is the K3V112?
A: Open-circuit, variable displacement, swashplate axial piston. Mainly used as the main hydraulic pump on excavators and other mobile equipment.
Q: Does "112" refer to the displacement?
A: Yes - 112 cc per revolution, per pump section.
Q: What's the pressure rating?
A: 34.3 MPa rated, 39.2 MPa peak. That's for the 112 size specifically.
Q: Single pump or double pump - which is available?
A: Both. The 112 range covers K3V112S (single), K3V112DT, K3V112DP, and K3V112DTP (double configurations).
Q: What's the operating speed range?
A: Max self-priming speed is 2360 rpm, absolute max is 2700 rpm.
Q: What hydraulic oil does it take?
A: Standard antiwear hydraulic fluid. Oil temperature range is -20°C to +95°C, viscosity 10–1000 cSt.
Q: Can you do OEM production?
A: Yes. We handle OEM orders - custom nameplate, packaging, and any order-specific requirements. Just let us know what you need upfront.
Q: What do you need from me to send a quote?
A: Model, rotation direction, control type, quantity, application, and destination country. Got a nameplate photo or pump label? Send it over - cuts the back-and-forth in half.
