Product details
1. Product General Introduction
The A10VSO18DR/31R-PKC62K01 is a classic swashplate-type variable Hydraulic piston pump manufactured by Bosch Rexroth, serving as the core power source of medium and light-duty industrial & engineering hydraulic system. As a mainstream open-circuit hydraulic pump, it realizes stepless flow regulation by changing swashplate inclination, featuring compact structure, low noise and high pressure resistance, widely matched for machine tools, material handling equipment, small engineering machinery and automated production line hydraulic system assemblies.
2. Complete Model Code Breakdown (A10VSO18DR/31R-PKC62K01)
1. A10VS: Series base code – standard axial piston variable assembly, the mature platform of Rexroth medium-pressure Hydraulic piston pump
2. O: Application mode – designed exclusively for open-loop hydraulic system, applied as a professional hydraulic pump
3. 18: Nominal displacement – 18 mL/r (18cc per revolution), small compact displacement for space-restricted installation scenarios
4. DR: Control mode – remote pressure control (constant pressure control), automatically adjusts pump output flow to maintain set system pressure, optimizing energy consumption of the whole hydraulic system
5. 31: Product generation – 31 standard mature series, universal spare parts compatibility for this batch of hydraulic pump
6. R: Rotation direction – clockwise rotation when viewing from the input shaft end face
7. P: Seal configuration – NBR nitrile rubber seals, compatible with conventional mineral hydraulic oil for general Hydraulic piston pump operation
8. K: Shaft extension – DIN standard splined shaft for high-torque power transmission connection
9. C: Mounting flange – SAE standard square flange, universal installation for global standard hydraulic system equipment frames
10. 62: Port layout code – side-mounted threaded inlet/outlet ports with dual independent case drain ports
11. K01: Special customization code – optimized internal clearance & anti-wear configuration for continuous heavy-duty running of the hydraulic pump

4. Structural Advantages & Performance Features
1. Adopts precision swashplate variable mechanism, DR constant pressure control stably stabilizes pressure fluctuation of the whole hydraulic system, reduces energy waste and heat generation of the hydraulic pump
2. High-precision piston-cylinder barrel matching assembly ensures high volumetric efficiency and minimal internal leakage, prolonging the service life of the entire Hydraulic piston pump
3. Equipped with dual case drain ports, excellent oil suction capacity, stable startup under low oil level conditions, strong adaptability to complex working conditions of on-site hydraulic system
4. Integrated through-drive design allows tandem assembly of additional small hydraulic pump or auxiliary pumps to expand hydraulic system functions
5. Optimized silencing structure lowers running noise, suitable for indoor precision equipment and environmental-friendly production lines
5. Alternative Models & OEM Part Number
- A10VSO18DR/31L-PKC62K01: Counterclockwise rotation alternative hydraulic pump, fully interchangeable in all parameters for reversed installation layout of hydraulic system
- A10VSO18DFR1/31R-PKC62K01: Pressure & flow compound control upgraded Hydraulic piston pump
- Original Factory Ordering Part No.: R902500093 (global standard stocking part number for bulk procurement)
6. Critical Operation & Maintenance Instructions
1. Two case drain ports of the hydraulic pump must be independently routed to the oil tank without backpressure; forbidden to connect with main return line to avoid damaging internal components and crashing the whole hydraulic system
2. Fully prime the pump cavity with hydraulic oil and exhaust air before commissioning to prevent dry grinding abrasion of the piston assembly of the Hydraulic piston pump
3. Operating oil temperature range: -10℃ ~ +75℃; install auxiliary cooling devices for long-time high-load operation of the hydraulic system
4. Equip a 10μm precision inlet filter to filter solid impurities and protect the precision friction pairs inside the hydraulic pump
