A10VSO71DR/31 Hydraulic Variable Displacement Axial Piston Pump In India
The A10VSO is a series of Bosch Rexroth variable displacement axial piston pumps, with model numbers like A10VSO18, A10VSO28, A10VSO45, A10VSO71, A10VSO100, A10VSO140, etc., indicating displacement (cm³/rev), followed by specific code letters for features like control type, series, and options, such as A10VSO45DFR1/31R-VPA12N00. These numbers define the pump’s exact specification, with the base code (A10VSO) identifying the pump type and series (e.g., Series 31). Our Model Number Same As We Replace Orbital Make Hydraulic Pump A10VSO & A10VO.
Structure of an A10VSO Model Number:
A typical A10VSO model number combines several segments to detail its specifications.
A10VSO: The base model/series (e.g., A10VSO).
Displacement (e.g., 18, 45, 71): Specifies the pump’s size in cubic centimeters per revolution (cm³/rev).
Control Type (e.g., DR, DFR, DFLR): Indicates the control mechanism (e.g., pressure relief, flow control).
Series (e.g., /31R): Identifies the pump’s design generation/series.
Options/Features (e.g., VPA12N00, VPB12N00): Denotes specific features like port types, seals, or special characteristics.
Key Benefits
Energy Efficiency: Smart controls (like load sensing) match output to demand, reducing energy waste and heat.
Precision Control: Offers precise, stepless flow adjustment and constant pressure/flow regulation, ensuring smooth operation.
High Performance: Good suction, high power-to-weight ratio, and fast response for demanding applications.
Versatility: Suitable for various industries (mobile, industrial) with multiple control options and through-drive for added pumps.
Durability & Reliability: Robust design and high-quality materials lead to long service life and easy maintenance.
Low Noise: Features a low-noise design, reducing sound emissions.
Specific Features & Advantages
Swashplate Design: Provides efficient, variable displacement for accurate flow.
Control Variants: Supports multiple control types (DR, DFR, DFLR) for pressure, flow, and power limitation.
Dual Case Drain Ports: Improves efficiency and reliability by evacuating internal leakage.
Through-Drive: Allows mounting other pumps (like gear pumps) coaxially for complex circuits.
Key Characteristics
Design: Axial piston with swashplate for variable displacement in open-circuit hydrostatic drives.
Flow Control: Stepless adjustment by changing the swashplate angle, proportional to drive speed and displacement.
Efficiency & Performance: High efficiency, good power-to-weight ratio, long service life, and reliable performance even at high temperatures.
Pressure Rating: Nominal pressure up to 280 bar (4000 psi), with peak pressures up to 350 bar.
Noise: Low noise level.
Suction: Excellent suction characteristics, crucial for mobile applications.
Controls: Versatile control options, including pressure/flow regulation (DFR/DFR1) for matching demand.
Connections & Mounting: SAE/ISO flange connections, with SAE A 2-bolt mounting common, and includes two case drain ports.
Applications: Widely used in mobile machinery (construction, agriculture) and industrial settings.
Through-Drive: Capability for multi-circuit systems via a through-drive (with a coverplate).
Key Specifications (Typical)
Nominal Pressure: 280 bar (4000 psi).
Peak Pressure: 350 bar (5000 psi).
Sizes: Ranges from 18 to 180 cm³/rev.
Circuit Type: Open.
