Reciprocating hydraulic pump K3V 63

axial pistonfor vehiclesopen circuit

Overview
The K3V / K5V series are variable displacement axial piston pumps with a swash plate design, engineered for mobile-hydraulic applications such as excavators, wheel loaders and cranes. Available in multiple rotary group layouts, including tandem (with PTO) and parallel configurations, the series is backed by over 25 years of mobile-application field experience.

Features

• High power density
• High suction capability
• Proven reliability in mobile applications
• Wide range of control and mounting options
