Description
K10VSO is a axial piston variable pump with hydrostatic drive shaft and swashplate design in open circuit. The flow of the axial piston variable pump is proportional to the drive speed and displacement, which can be steplessly changed by adjusting the swashplate angle. The open circuit axial piston pump is equipped with SAE flange UNC or SAE flange metric with two drain ports. The pump is tested to be high-speed, excellent suction performance, low noise, with high power/weight ratio. Variable displacement includes modes of constant pressure, constant power/constant flow, and constant power mode. The through drive design can be applied in multi-circuit systems. Our axial piston variable pump is widely used in metallurgy, mining, engineering machinery, shipping, civil aviation facility and other hydraulic transmission fields.
