Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
The K3V112 is part of Kawasaki’s highly regarded K3V series — a line of axial piston variable displacement pumps specifically designed for excavators and other heavy-duty hydraulic machinery.
Featuring a displacement of 112 cm³/rev, the K3V112 balances power and efficiency, delivering consistent oil flow under high pressure for key machine operations such as digging, lifting, swinging, and traveling. Its design supports either single or tandem pump configurations, allowing integration with machines requiring multi-circuit control.
Why Choose the K3V112?
- Optimized for Mid-to-Large Excavators: Offers the ideal displacement and flow rate for 20–30 ton class machines.
- High Operating Pressure: Can handle pressures up to 34.3 MPa, suitable for intense construction and mining tasks.
- Long Component Life: Key parts such as cylinder blocks and pistons are made from wear-resistant alloy steel and precision-ground for low friction.
- Flexible Regulator Options: Available with mechanical, hydraulic, or electronic control regulators to suit your excavator’s hydraulic control logic.
- Excellent Heat Resistance: Designed for reliable operation even in high-temperature environments or extended-duty cycles.
