Compatibility & Applications
Direct Replacement Information
This Fluidyne unit serves as a direct replacement for Vickers WF825657 in systems requiring 19.5 cm³/r (1.19 in³/r) displacement and 2500 PSI maximum pressure..
- Mounting Pattern: SAE J744 ‘A’ 2-bolt
- Inlet Port: G1″ BSPP
- Outlet Port: G1/2″ BSPP
Common Applications
Commonly used in marine applications, stationary power units, test stands. For similar displacement and performance in single-stage designs, see the V201P5P18C11R – FluiDyne V20 Pump.
- marine applications (see also V201P13P3A11R – FluiDyne V20 Pump for large marine circuits)
- stationary power units
- test stands
Important: Verify pump model WF825657 matches your existing Vickers unit before ordering. For technical assistance, contact (800) 823-4937.
Product Selection Guide
These FluiDyne V2020 double vane pump models differ mainly by their combined flow rates, pump section sizes (GPM per side), maximum speed limits, port orientations, shaft types, and rotation direction. All are 100% direct replacements for Vickers and share SAE ‘B’ 4-bolt flange mounting with standard ports, ensuring easy system integration.
?? 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 |
|---|---|---|---|---|
| WF825657 (Current) | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825659 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825654 | 7 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825651 | 8 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825975 (V20201F10S10S11AA30L) | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Total Flow Rate (GPM)
Difference: WF825657 delivers the highest total flow at 18.0 GPM (front 11 + rear 7), while WF825975 offers the lowest at 10.0 GPM (front 10 + rear 0). WF825654 and WF825651 each provide 14.0 GPM, and WF825659 delivers 12.0 GPM.
Selection Guide: Select WF825657 for applications needing up to 18 GPM; choose WF825654 or WF825651 for balanced flow at 14 GPM; opt for WF825975 or WF825659 for lower total flow needs.
Pump Section Sizing
Difference: Models differ in GPM split between front and rear pumps: WF825657 (11/7), WF825654 (7/7), WF825651 (8/6), WF825659 (11/1), WF825975 (10/0).
Selection Guide: Choose a model with a higher front section if your system requires a primary high-flow circuit, or a balanced model like WF825654 for dual circuits with similar flow needs.
Maximum Speed
Difference: WF825654 supports the highest speed (3000 RPM), followed by WF825651 (2800 RPM), WF825657 (2500 RPM), WF825659 and WF825975 (1800 RPM).
Selection Guide: If high-speed operation is critical, select WF825654; use WF825659 or WF825975 for systems where lower maximum speed suffices. For even higher-speed, lower-volume needs, view our single stage vane pump options.
Rotation Direction
Difference: WF825657, WF825654, and WF825975 are left-hand (counter-clockwise); WF825651 and WF825659 are right-hand (clockwise).
Selection Guide: Choose a model matching your system’s required pump rotation.
Shaft Type
Difference: WF825654 and WF825975 offer 13-tooth splined shafts; others have straight keyed shafts.
Selection Guide: Select splined shaft models for high-torque or heavy-duty coupling requirements.
Port Orientation
Difference: WF825657, WF825654, and WF825651 have both outlets inline with the inlet (0°); WF825659 has outlets 90° CCW from inlet; WF825975 has outlets opposite inlet (180°).
Selection Guide: Pick the port orientation that best suits your system plumbing: inline for direct connections, 90° or 180° for space-constrained layouts.
Quick Selection Guide
If you need: Highest total flow with balanced dual circuits
Choose: WF825657 (11+7 GPM, left-hand, inline ports, straight keyed shaft)
Because: Provides maximum flow and flexibility for dual hydraulic circuits.
If you need: Equal flow from both pump sections at highest speed
Choose: WF825654 (7+7 GPM, left-hand, inline ports, 13-tooth splined shaft, 3000 RPM)
Because: Ideal for two circuits with identical flow demands and high-speed operation.
If you need: Moderate flow, right-hand rotation, and inline ports
Choose: WF825651 (8+6 GPM, right-hand, inline ports, straight keyed shaft, 2800 RPM)
Because: Suited where moderate flows and right-hand rotation are required.
If you need: High primary flow with minimal secondary flow, 90° port orientation
Choose: WF825659 (11+1 GPM, right-hand, 90° CCW ports, straight keyed shaft, 1800 RPM)
Because: Best for Hi-Lo circuits needing a dominant primary section and unique plumbing layout.
If you need: Single-section operation (front only), left-hand rotation, or 180° port orientation
Choose: WF825975 (10+0 GPM, left-hand, 180° ports, 13-tooth splined shaft, 1800 RPM)
Because: Fits systems requiring only one active section and unique port layout.
Compatibility: All models are direct Vickers replacements and share SAE ‘B’ 4-bolt flange mounting with standard 1-1/16″-12 UN-2B and G1″/G1/2″ BSPP straight thread ports for straightforward interchangeability.
