Hydraulic axial piston pump K7V series

open circuithigh-capacityvariable-displacement

Overview
The K7V series are variable displacement axial piston pumps of swash plate design for open-loop mobile hydraulic systems. They are used on mobile machinery such as excavators, cranes and wheel loaders. Kawasaki Heavy Industries technologies improve hydraulic efficiency and reduce noise; robust bearing capacity and a thicker shaft extend service life.

Features

• High pump efficiency
• Low noise
• High reliability
• High power density

Control Curve
Control curves and example graphs are provided to illustrate control performance and pump behavior under various operating conditions.

Applications

• Excavators
• Wheel loaders
• Crawler drills / pile drivers
• Cranes (crawler / rough terrain)
• Crushers
• Concrete pumps
