K4VSM Axial Piston Variable Motor, K4VSM

For open or closed circuits Sizes 40-500 Maximum nominal pressure 350 bar Maximum peak pressure 420 bar

K4VSM series axial piston variable motor is specially designed for high-pressure engineering machinery. The engine is an oblique axial piston pump with a spherical valve, large runner and shaft drive. The product is suitable for open and closed-circuit hydrostatic drive.

Features Through shaft variable displacement piston motor, high rigidity casing and integral swash plate, specially designed for hydrostatic drive in open and closed circuits Flow proportional to speed, suitable for variable speed drive Proportional speed regulation motor, electronically controlled to adjust the cradle which can steplessly change the output speed 100% torque transmission through the shaft for mounting additional pumps High power/weight ratio Steplessly variable spherical flow, displacement from 50% Vmax to Vmax Swashplate angle indicator, observe the working state of the pump directly Suitable for drives that need high reliability, high pressure, long service life and wide speed range Technical Parameters
