Variable axial piston pump Kawasaki K3VL80

The K3VL80 pump from the Kawasaki K3VL series is a variable displacement axial piston pump of swashplate design for open circuits, known for high efficiency and low noise.

Key specifications of K3VL80

• Displacement: 80 cc/rev
• Working pressure: 320 bar
• Maximum pressure: 350 bar
• Displacement type: Variable
• Piston arrangement: Axial

These values come from the manufacturer's published data. The full list is in the specifications tab.

Applications

• Industrial machinery
• Heavy machinery
• Power units

How it works

In an axial piston pump, the pistons sit in a rotating cylinder block and the angle of the swashplate sets their stroke. On variable displacement models a controller changes that angle, so the pump delivers only what the circuit needs. The result is high efficiency and less heat in high-pressure circuits.

About the brand

Kawasaki is a Japanese maker of piston pumps and motors, widely used in heavy machinery and industrial applications.

Selection and maintenance

A piston pump is more sensitive to contaminated oil than a gear pump, so keep the oil cleanliness level given in the datasheet. Fill the pump case with oil before start-up and keep the case drain line separate and free of pressure. Rising drain leakage, pressure swings and a hot pump are signs of internal wear.
