1. Model Breakdown and Brand Background
• Full Model: A2FE125/6.1-WVAL181
• Brand Association:
• Commonly found inRexroth (Bosch Rexroth)hydraulic product lines as a swashplate axial piston pump.
• Similar models may appear inKawasakiorParkerhigh-end hydraulic systems, but verification against official data is required.
Model Segmentation Explanation
【表格】
Segment Description
A2FE Series code: Swashplate axial piston pump (A2F = variable displacement; E = electric drive or specific control mode)
125 Displacement: 125 cm³/rev (determines maximum flow rate)
/6.1 Control mode code: 6.1 may indicate pressure compensation or load-sensing control (confirm via manual)
-WVAL181 Interface and configuration code:
- **W**: Potentially water-cooled or special seal design - **V**: Integrated valve block (e.g., built-in pressure valve) - **A**: Axial mounting orientation - **L181**: Flange or port standard (e.g., ISO 181 or custom code) |
2. Core Technical Specifications
Performance Metrics
【表格】
Parameter Description
Displacement 125 cm³/rev (Theoretical flow = displacement × RPM; e.g., 187.5 L/min at 1500 RPM)
Rated Pressure 350 bar (continuous operating pressure; some models up to 400 bar)
Peak Pressure 420 bar (short-term allowable pressure, typically ≤10% operating time)
Speed Range 600–2500 RPM (compatible with diesel engines or electric motors)
Control Mode Load-sensing (LS), pressure compensation (PC), or electro-hydraulic proportional control (confirm via /6.1 code)
Weight ~85–120 kg (heavier with integrated valve blocks or cooling systems)
Fluid Temperature -20°C to +80°C (requires viscosity grade matching, e.g., ISO VG46 hydraulic oil)
Interfaces and Installation
• Input Shaft: SAE flywheel housing or keyed shaft (matches motor/engine couplings).
• Hydraulic Ports:
• P Port(High-pressure outlet): Typically SAE B or ISO 6162-1 flange.
• T Port(Return): Connects to tank; recommended filtration ≤10μm.
• X/Y Ports(Control oil): For remote pressure adjustment or proportional valve control.
• Mounting: Flange-mounted (e.g., ISO 4401) or foot-mounted (confirm via L181 code).
