Common Applications
Commonly used in agricultural equipment, construction machinery, utility vehicles. For more real-world examples, see our case studies on single stage vane pumps applications in diverse hydraulic systems.
- agricultural equipment
- construction machinery
- utility vehicles
Important: Verify pump model WF825129 matches your existing Vickers unit before ordering. For technical assistance, contact (800) 823-4937. Same-day shipping is available on in-stock items, and all pumps are covered by a 12-month manufacturer warranty. Volume pricing starts at 4 units.
Product Selection Guide
These Fluidyne V2020 double vane pump models differ primarily in their total flow/output, speed ratings, port orientation, and shaft type. All are direct Vickers replacements with SAE ‘A’ 2-bolt mounting and identical port sizes, making them interchangeable for most installations. Explore the full range of vane pumps for alternative options. The main selection factors are total flow requirements, desired pump speed, and connection orientation.
?? Important: The specifications shown are for reference and comparison purposes. Always verify specifications with the official manufacturer documentation or contact our technical team at (800) 823-4937 before ordering to ensure compatibility with your application. We cannot accept returns due to specification mismatches.
| Model Number | Flow Rate | Max Pressure | Displacement | Mounting |
|---|---|---|---|---|
| WF825129 (Current) | 9 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825125 | 13 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825127 | 6 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825121 | 7 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825124 | 8 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Total Flow Rate
Difference: Models range from 12.0 GPM (WF825127) to 20.0 GPM (WF825125).
Selection Guide: Select higher flow models like WF825125 (20.0 GPM) for systems with larger actuators or higher throughput. Lower flow models like WF825127 (12.0 GPM) are suited for precise, lower-demand circuits.
Front/Rear Pump Output
Difference: Front pump GPM varies by model (6, 7, 8, 9, 13 GPM); rear pump varies from 6 to 8 GPM.
Selection Guide: Choose models (e.g., WF825125) with higher front pump GPM for circuits requiring more flow to one section. Balanced output (e.g., WF825124, both 8 GPM) is ideal for systems needing equal flow from each section.
Maximum Speed (RPM)
Difference: Max speed ranges from 2400 RPM (WF825125) to 3400 RPM (WF825127).
Selection Guide: When pairing with high-speed motors, select WF825127 (3400 RPM) for faster response or operations requiring quick cycling. Lower speed models (WF825125, 2400 RPM) are appropriate for slower, higher-torque applications.
Port Orientation
Difference: WF825129/125/127 have both outlets inline (0°); WF825121 has outlets 90° CW from inlet; WF825124 has outlets opposite inlet (180°).
Selection Guide: Inline orientation (0°) simplifies straight piping runs. 90° or 180° configurations aid in installations with space constraints or where piping must turn sharply.
Shaft Type
Difference: WF825127 and WF825129 have 13-tooth splined shafts; other models use straight keyed shafts.
Selection Guide: Select splined shafts (WF825127/129) for higher torque transfer or when coupling with splined drive motors. Use straight keyed shafts for standard hydraulic motor connections.
Quick Selection Guide
If you need: Highest total flow (20.0 GPM) with greater front pump output
Choose: WF825125
Because: Best for systems requiring maximum flow rate and a strong primary circuit.
If you need: Balanced dual output with moderate flow (both 8 GPM)
Choose: WF825124
Because: Ideal for twin-actuator systems where equal flow is required.
If you need: High-speed operation (up to 3400 RPM) with equal front/rear output
Choose: WF825127
Because: Suited for fast-cycling or rapid-response hydraulic systems.
If you need: Standard flow with inline ports and splined shaft
Choose: WF825129
Because: Offers 16 GPM total flow, inline outlets, and robust splined shaft for high torque applications.
If you need: Compact piping with side-exit ports (90°)
Choose: WF825121
Because: Facilitates installations where space is limited and piping must change direction.
Compatibility: All models are 100% interchangeable with Vickers equivalents, feature SAE ‘A’ 2-bolt flange mounting, and standard G1″/G1/2″ BSPP straight thread ports for universal fit.
