Description

The K4VSG is an axial piston variable pump with axial piston rotary group in swashplate design for hydrostatic drives in closed circuits. The flow of the variable displacement pump is proportional to the drive speed and displacement, which can be steplessly changed by adjusting the cradle. The pistons are axially arranged to the drive shaft in its axial piston unit with swashplate design. Hydraulic fluid flows from the hydraulic pump to the motor and directly back to the pump in a closed circuit. The series is mainly used in tunnel boring machine, mining machines, ceramic press, metallurgy and other industries.
