Product Selection Guide
These vane pumps from FluiDyne’s V2020 series are all direct Vickers replacements (Vickers replacement pumps), but differ in total flow, port orientation, rotation direction, shaft type, and certain control features. The key to choosing the right model lies in matching your required flow rate, system rotation direction, port layout, and whether you need standard or pumps with integral valves for flow control options.
?? 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 |
|---|---|---|---|---|
| WF825501 (Current) | 13 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825506 | 12 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825975 | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825063 | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825884 | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Total Flow Rate
Difference: WF825501 delivers the highest total flow at 22.0 GPM (13 GPM front + 9 GPM rear), followed by WF825506 at 21.0 GPM (12 GPM front + 9 GPM rear). WF825975, WF825063, and WF825884 each deliver 10.0 GPM (front pump only, rear pump inactive), such as the V20201F10S10S11AA30L – FluiDyne V2020 applications.
Selection Guide: For applications needing higher combined flow or dual-circuit operation, select WF825501 or WF825506. For lower-flow, single-circuit needs, choose WF825975, WF825063, or WF825884.
Pump Configuration / Control
Difference: WF825506 includes flow control with internal drain, allowing for pressure settings and specialized circuit requirements. The other models are standard double pumps.
Selection Guide: If your system requires integrated flow control or dedicated internal drainage, WF825506 is the best choice. For other single stage vane pumps, see available models.
Rotation Direction
Difference: WF825501 and WF825506 are right-hand (clockwise). WF825063 is also right-hand (clockwise), while WF825975 and WF825884 are left-hand (counter-clockwise).
Selection Guide: Match the pump rotation to your system’s drive direction—choose right-hand models for clockwise-driven applications and left-hand for counter-clockwise.
Port Orientation
Difference: WF825501 and WF825506 have both outlets 90° CCW from inlet. WF825975 and WF825063 have outlets opposite inlet (180°). WF825884 has outlets inline with inlet (0°).
Selection Guide: Select the model with port orientation that best fits your piping layout. 90° outlets are ideal for side connections; 180° or 0° for straight or opposite porting.
Shaft Type
Difference: WF825501 and WF825506 feature straight keyed shafts. WF825975, WF825063, and WF825884 list 13-tooth splined shafts in their descriptions but also reference straight keyed shaft in the summary specs.
Selection Guide: For high-torque or splined coupling systems, choose models with splined shafts. Users seeking similar performance may also consider the V201P5P18C11R – FluiDyne V20 Pump. For standard couplings, straight keyed shafts are suitable.
Maximum Speed
Difference: WF825501 and WF825506 operate up to 2400 RPM (limited by front pump). WF825975, WF825063, and WF825884 are limited to 1800 RPM (by rear pump).
Selection Guide: If your drive runs above 1800 RPM, select WF825501 or WF825506.
Quick Selection Guide
If you need: Highest combined flow (22.0 GPM) for dual-circuit systems
Choose: WF825501
Because: It delivers the greatest total flow with a balanced front/rear output and 2400 RPM max speed.
If you need: Integrated flow control with internal drain and adjustable pressure
Choose: WF825506
Because: It offers a built-in control valve for precise flow/pressure management.
If you need: 10 GPM output with counter-clockwise (left-hand) rotation
Choose: WF825975 or WF825884
Because: These models match left-hand drives, with port orientation options for your layout.
If you need: 10 GPM output with clockwise (right-hand) rotation
Choose: WF825063
Because: This model matches right-hand rotation for standard drive systems.
If you need: Specific porting orientation (0°, 90°, 180°) to match piping
Choose: WF825501/WF825506 for 90°, WF825975/WF825063 for 180°, WF825884 for 0°
Because: Choose based on your required piping direction for easiest installation.
Compatibility: All models comply with SAE ‘A’ 2-bolt flange mounting and G1″/G1/2″ BSPP straight thread ports. They are 100% interchangeable with Vickers V2020 double vane pumps, ensuring direct replacement in existing hydraulic systems. For similar applications, see V201P13P3C11R – FluiDyne V20 Pump.
