REXROTH A15VSO Series Hydraulic Pump
1. Model Explanation
-
The series is specialized for open-loop hydraulic systems , providing diverse control options to meet the precise load and flow regulation demands of industrial and heavy-duty mobile equipment.
-
Constructed with high-strength cast iron housing and wear-resistant seals , it exhibits strong adaptability to harsh working conditions such as high temperature, heavy dust, and pressure shocks , ensuring extended service life and low maintenance requirements.
-
Optional integrated components include pressure relief valves, anti-cavitation valves , and flushing oil ports. These configurations must be specified in the model’s configuration code to match system-specific operational needs.
-
Interface specifications cover SAE flanges (series 10, 32, 63) and metric threaded ports , with the specific type, rotation direction, and installation dimensions clearly encoded in the middle section of the model.
-
A15VSO: Series identifier (open-loop swashplate-type axial piston variable pump with high volumetric efficiency)
-
175: Rated displacement (175 cm³/r, corresponding to maximum swashplate angle)
-
DR: Control mode (constant pressure control with manual override function, supporting stepless flow adjustment)
-
10R: Interface & rotation direction (10-series SAE flange, right-hand rotation of drive shaft)
-
PPB13N00: Configuration code (standard mounting, integrated flushing oil port, general-purpose seal material)
2. Core Specifications
2.1 Displacement Range
-
Standard Models: 40 cm³/r to 355 cm³/r (covering A15VSO40, A15VSO71, A15VSO175, A15VSO250, A15VSO355, etc.)
-
Stepless Adjustment: Displacement is continuously adjustable via swashplate angle regulation, enabling precise flow matching with variable load demands, and improving system energy efficiency.
2.2 Operating Pressure
-
Nominal Pressure: 32 MPa (4641 PSI) for all displacement models, ensuring stable performance under long-term high-load operations.
-
Peak Pressure: 40 MPa (5802 PSI) for short-term operation (≤10 minutes, non-recurrent) to handle occasional overload conditions in harsh working scenarios.
2.3 Speed Range
-
Rated Speed: 1500 – 2800 rpm (varies by displacement, optimized for industrial motor and diesel engine matching)
-
Minimum Stable Speed: ≥100 rpm (no cavitation, ensuring smooth startup and low-speed operation of precision equipment)
-
Maximum Allowable Speed: 3000 rpm (continuous operation for models ≤250 cm³/r); 2800 rpm for models >250 cm³/r to protect shaft bearings and reduce wear.
2.4 Other Key Parameters
-
Noise Level: ≤68 dB (at rated speed and nominal pressure, lower than industry average for high-pressure open-loop pumps)
-
Working Temperature: -25℃ to 95℃ (hydraulic oil temperature); recommended operating range 15℃ – 60℃ for optimal efficiency and seal durability.
-
Hydraulic Oil Compatibility: Mineral oil (complying with DIN 51524), synthetic hydraulic oil, and biodegradable hydraulic oil for eco-sensitive applications.
-
Drive Shaft Load Capacity: Radial load ≤ 4000 N; Axial load ≤ 1800 N, enhancing durability under heavy-duty drive conditions and reducing bearing failure risk.
-
Volumetric Efficiency: ≥92% at rated working conditions, minimizing internal leakage and improving energy utilization.
3. Product Features
-
High-Efficiency Open-Loop Design: Optimized for open hydraulic systems, featuring excellent oil suction performance and stable flow output, suitable for equipment requiring independent oil tank circulation and high-precision flow control.
-
Versatile Control Modes: Supports constant pressure control (DR), power control (LR), electric proportional control (EO2), and manual control, adapting to both manual operation and automated control systems of modern industrial equipment.
-
Enhanced Structural Durability: Equipped with high-precision hardened swashplate, wear-resistant cylinder block, and hydrostatically balanced bearings, reducing friction and wear, and ensuring reliable operation under extreme pressure conditions.
-
Integrated Maintenance Design: Built-in flushing oil ports (K1/K2) for regular removal of metal particles and contaminants, extending service life and simplifying maintenance processes.
-
Global Certification & Compatibility: Complies with CE, UL, and ISO 9001 standards, compatible with international hydraulic system configurations, suitable for global industrial and heavy machinery markets.
-
Wide Application Scope: Ideal for metallurgical equipment, oil drilling platforms, port cranes, large construction machinery (excavators, bulldozers), and heavy industrial hydraulic systems requiring high reliability and efficiency.
