open circuitopencompact

Product overview
The K3VLS series are variable displacement axial piston pumps (swash plate design) for open-loop hydraulic systems. Designed for mobile machinery and industrial vehicles, the series delivers compact installation size, reduced mass and flexible control options to match medium-pressure applications.

Features

• Efficient swash-plate design for improved volumetric and mechanical performance
• Compact and lightweight construction for flexible mounting in tight engine compartments
• Low noise operation suitable for mobile equipment
• Responsive and stable control characteristics across operating ranges
