Product Selection Guide
These FluiDyne V2020 double vane pump models are all direct Vickers replacements, fully SAE J744 compatible, and support up to 2500 PSI. Their main differences are in flow rates, GPM distribution between front/rear pumps, maximum speed, port orientation, shaft style, and rotation direction. Selection depends on required total flow, individual circuit flows, porting layout, and drive compatibility—see our single stage vane pumps for further 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 |
|---|---|---|---|---|
| WF825651 (Current) | 8 | 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) |
| WF825657 | 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) |
| WF825975 | 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 offers the highest total flow at 18.0 GPM (11 GPM front + 7 GPM rear)—similar to the V20 Series for high-demand dual circuits, WF825651 and WF825654 both deliver 14.0 GPM (8+6 and 7+7 GPM), WF825659 provides 12.0 GPM (11+1 GPM), and WF825975 offers 10.0 GPM (10+0 GPM) applications.
Selection Guide: Choose WF825657 for applications needing the highest combined flow or two strong simultaneous circuits. Select WF825651 or WF825654 for balanced dual flows or if 14 GPM is sufficient. Choose WF825659 or WF825975 for lower flow requirements or when one circuit needs minimal flow.
Front/Rear Pump Flow Split
Difference: WF825651: 8 GPM front, 6 GPM rear. WF825657: 11 GPM front, 7 GPM rear. WF825654: 7 GPM front, 7 GPM rear. WF825659: 11 GPM front, 1 GPM rear. WF825975: 10 GPM front, 0 GPM rear.
Selection Guide: WF825654 is ideal for systems needing equal flow to both circuits. WF825657 and WF825651 are suitable when the front circuit requires more flow than the rear. WF825659 and WF825975 fit applications where the rear circuit is auxiliary or requires minimal/zero flow, like those handled by V201P13P3A11R models.
Maximum Speed (RPM)
Difference: WF825654 allows up to 3000 RPM, WF825651 up to 2800 RPM, WF825657 up to 2500 RPM, WF825659 and WF825975 limited to 1800 RPM.
Selection Guide: If your drive system operates at higher RPMs, select WF825654 or WF825651. For lower RPM drives, WF825659 and WF825975 are suitable.
Port Orientation
Difference: WF825651 and WF825654: outlets inline with inlet (0°); WF825657: inline (0°); WF825659: outlets 90° CCW from inlet; WF825975: outlets opposite inlet (180°).
Selection Guide: Choose port orientation to match your piping layout—inline (0°) for straight-through connections, 90° for compact installations, or 180° for opposite-side connections.
Shaft Style
Difference: WF825651, WF825657, WF825659: straight keyed shaft; WF825654, WF825975: 13-tooth splined shaft.
Selection Guide: Use straight keyed shafts for general applications and splined shafts for higher torque or when splined coupling is required by your drive.
Rotation Direction
Difference: WF825651, WF825659: right-hand (clockwise); WF825657, WF825654, WF825975: left-hand (counter-clockwise).
Selection Guide: Choose the model with the correct rotation for your motor or drive configuration.
Quick Selection Guide
If you need: Highest total flow and robust dual-circuit capability
Choose: WF825657 (11+7 GPM, 18.0 GPM total)
Because: Best for demanding systems requiring strong flows to both circuits, with left-hand rotation.
If you need: Balanced flows to two circuits at moderate total flow
Choose: WF825654 (7+7 GPM, 14.0 GPM total)
Because: Ideal for equal circuit demands, highest permissible speed (3000 RPM), splined shaft, left-hand rotation.
If you need: Moderate, slightly unbalanced flows and right-hand rotation
Choose: WF825651 (8+6 GPM, 14.0 GPM total)
Because: For applications where the front circuit needs more flow, compatible with right-hand drive.
If you need: High front flow with minimal or auxiliary rear circuit
Choose: WF825659 (11+1 GPM, 12.0 GPM total)
Because: Ideal where primary flow is needed on one section, with 90° porting and right-hand rotation.
If you need: Single-circuit operation or rear section as a bypass
Choose: WF825975 (10+0 GPM, 10.0 GPM total)
Because: Use when only one circuit is active or rear section is not required; left-hand rotation, 180° ports, splined shaft.
Compatibility: All models are 100% interchangeable with Vickers equivalents, conform to SAE J744 mounting, and use G1″/G1/2″ BSPP ports. Select based on flow, speed, shaft, porting, and rotation to match your existing system.
