Hydraulic Axial Piston Pump,CJA10VSO Series

Variable Displacement Pump,Hydraulic Pump,Hydraulic Pump for Hydraulic System,Pump for Hydraulic Press

CJA10VSO series swash plate type hydraulic axial piston pump is applied in open-loop hydruaic system.Its flow,driving speed,anddisplacement are designed to be in proportion.User can control the stepless variable by adjusting the inclination of the swash plate.The flanges of the piston pump are mounted according to SAE-UNC SAE or standards.The pump is equipped with 2 drain outlets.Its driving shaft is capable of bearing both the axial and the radial loads.The hydraulic pump can support high-speed running of hydraulic system.With good oil absorption capacity,low noise,high power/weigh ratio,long service life,short contrlo cycle,and wide control range,CJA10VSO hydraulic axial piston pump is widely applied in the shaft drive of multi-loop system.

 

Feature:

The CJA10VSO series axial piston pump in swash plate design for hydraulic devices in open loop circuit.The flow is proportional to the drive speed and the displacement,by adusting the angle of the plate can infinitely varies the flow.

--Mounting flange based on the SAE-UNC or SAE metric system

--2 case drain ports

--Permit high rotary speed

--Excellent suction characteristics

--low noise

--high power/weight ratio

--long service life

--short control time

--the drive shaft can bear load from axial and radial direction

--wide control range

--Through drive option for multiple pump system

Applications

CJA10VSO series hydraulic axial piston pump is mainly applied in the medium/high pressure hydraulic system of hydraulic press.engineering machineries,mining machinery,and metallurgy equipment,just to name a few.
