Quantitative hydraulic pump A2FE80 90 series displacement motor plunger pump manufactured by Rexroth in Germany
Product Overview
The A2FE series axial piston hydraulic motors are fixed-displacement motors designed for high-pressure hydrostatic drives in open or closed circuits. These motors feature a spherical piston design with robust construction, providing reliable performance in demanding industrial and mobile appliions.
Key Features & Benefits
High Pressure Operation: Continuous operating pressure up to 32 MPa, with peak pressure tolerance up to 31.5 MPa
Spherical Piston Design: Self-aligning piston and cylinder block interface reduces wear and enhances efficiency
Compact Installation: Central flange mounting allows for space-saving integration
High Power Density: Optimized design delivers high torque output in a compact package
Construction Equipment: Drilling rigs, pile drivers, compactors
Agricultural Machinery: Combine harvesters, tractors, irrigation systems
Installation Guidelines
Pre-Installation Checks
Verify motor shaft rotates freely by hand
Check for any visible damage during transport
Ensure mounting surface is clean and flat
Confirm hydraulic connections match port sizes
Mounting Procedure
Alignment: Ensure motor shaft aligns with driven equipment without imposing radial or axial loads
Bolting: Use evenly tightened bolts (recommended torque: 80-100 Nm for M12 bolts)
Coupling: Use flexible coupling to accommodate minor misalignments
Port Connections: Use appropriate seals and ensure connections are leak-free
Hydraulic System Requirements
Fluid Cleanliness: NAS 1638 Class 8 or better (ISO 4406 18/16/13)
Filtration: Use filters with β₍₁₀₎ ≥ 100
Oil Viscosity: 27-43 mm²/s at operating temperature
System Flushing: Flush system before motor installation
Maintenance & Operation
Start-Up Procedure
Fill system with recommended hydraulic fluid
Vent air from system (crack connections at highest points)
Start system at low pressure and check for leaks
Gradually increase pressure to operating level
Monitor temperature during initial operation
Routine Maintenance
Daily: Check for leaks, unusual noise, or vibration
Weekly: Check oil level and condition
Every 500 hours: Check filter condition
Every 1000-3000 hours: Change hydraulic oil (depending on operating conditions)
Every 2000 hours: Check mounting bolts and connections
Troubleshooting Signs
Low Speed: Check system pressure and flow
Overheating: Check oil level, cooling system, and load conditions
Noise/Vibration: Check for air in system or mechanical issues
Leakage: Check seals and connections
Frequently Asked Questions
What is the main difference between A2FE80 and A2FE90 models?
The primary difference is displacement: A2FE80 models have 80 cm³/rev displacement, while A2FE90 models have 90 cm³/rev. This means A2FE90 motors can deliver approximately 12.5% higher torque at the same pressure, making them suitable for appliions requiring more power. Physical dimensions and mounting may be similar, but torque output and flow requirements will differ.
What does the "VZL192J-K" suffix indie compared to other suffixes?
The "VZL192J-K" suffix typically indies a special configuration with specific porting, sealing, or mounting features. The "192" number may refer to a specific design variation, while "J" and "K" suffixes often indie special sealing arrangements or enhanced features. This configuration may be optimized for specific appliions or system requirements. Always refer to the specific product datasheet for exact configuration details.
What does the "VAL100" suffix mean, and how does it differ from "VAL027-S"?
The "VAL100" suffix likely indies a different porting arrangement, connection size, or internal configuration compared to "VAL027-S". The numerical values (100 vs 027) typically refer to specific port sizes, mounting dimensions, or design variations. "VAL" generally indies standard open circuit configuration, but the numerical suffix determines the exact specifiions. Always consult the manufacturer's documentation for precise differences.
Can these motors operate at speeds below 100 rpm?
While the recommended continuous operating range is 100-2800 rpm, some models may operate at lower speeds for intermittent periods. However, operation below 100 rpm may result in reduced efficiency, increased wear, and potential lubriion issues. For continuous low-speed operation, consult the manufacturer for specific recommendations or consider using a gear reduction unit.
How do I determine the hydraulic flow requirements for these motors?
Flow requirement (L/min) = Displacement (cm³/rev) × Speed (rpm) ÷ 1000. For example, an A2FE90 motor at 1500 rpm requires approximately 135 L/min (90 × 1500 ÷ 1000). Actual flow should be slightly higher to account for internal leakage and efficiency losses. Always ensure your hydraulic pump can supply the required flow at the operating pressure.
Warranty & Support
These products typically carry a standard warranty period of 12 months from date of installation or 18 months from date of shipment (whichever comes first), subject to proper installation and operation within specified parameters. Warranty terms may vary by manufacturer and region. For technical support, contact authorized service centers with the complete model number and serial number.
