Hydraulic axial piston pump K3VG series

electro-hydraulicopen circuitlow-noise

Overview
The K3VG series are variable-displacement axial piston pumps with a swash plate design for industrial equipment. Designed for open-loop systems, they support multiple control strategies including flow, pressure and horsepower control. An optional ILIS electric-hydraulic servo regulator provides high-accuracy command-based flow control.

Features

• High pump efficiency
• Wide range of control options (flow, pressure, horsepower, combinations)
• Low noise operation
• Compatible with fire-resistant fluids
• Durable design for long service life
• Available dual-pump (DT) variants for higher displacement

Applications

• Plastic injection and die casting machinery
• Press machines
• Metalworking plants
• Wastewater and sludge treatment equipment
• Tunnel boring machines
• Cargo vessels and tankers (marine hydraulics)
