Product Selection Guide
These FluiDyne V2020 double vane pump models are all direct Vickers replacements, sharing core mounting and port standards, but differ primarily in flow rates, port orientations, shaft types, rotation direction, and the presence of a priority valve. For a broader selection, see our vane pumps category. These differences affect their suitability for specific hydraulic circuits, installation layouts, and system demands.
?? 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 |
|---|---|---|---|---|
| WF825847 (Current) | 8 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825841 | 11 | 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: WF825847 delivers 16.0 GPM (8 GPM front + 8 GPM rear), WF825841 delivers up to 19.0 GPM (11 GPM front + 8 GPM rear), while WF825975, WF825063, and WF825884 each provide 10.0 GPM (10 GPM front only, 0 GPM rear).
Selection Guide: Choose WF825841 for the highest total flow needs, WF825847 for balanced dual-section flow, and WF825975, WF825063, or WF825884 for single-section flow requirements.
Priority Valve
Difference: Only WF825841 includes a priority valve cover, enabling prioritized flow for essential circuits.
Selection Guide: Select WF825841 for systems requiring managed flow distribution—such as steering plus auxiliary hydraulic functions.
Rotation Direction
Difference: WF825847 and WF825063 are right-hand (clockwise); WF825975 and WF825884 are left-hand (counter-clockwise); WF825841’s rotation is not specified.
Selection Guide: Confirm your system’s rotation direction—choose a matching pump to avoid installation issues.
Port Orientation
Difference: WF825847 has both outlets 90° CW from inlet; WF825841 is 90° CCW; WF825975 and WF825063 are 180° (opposite); WF825884 is 0° (inline).
Selection Guide: Match port orientation to your plumbing for easiest installation—use 0° or 180° for straight-through layouts, 90° for right-angle connections.
Shaft Type
Difference: WF825847, WF825975, WF825063, and WF825884 use a 13-tooth splined shaft; WF825841 uses a 3/4″ straight shaft with key (1.75″ extension).
Selection Guide: Select splined shafts for high-torque or flexible couplings; use keyed shafts for standard couplings.
Maximum Speed
Difference: WF825847 supports up to 2800 RPM; WF825841 up to 2500 RPM; WF825975, WF825063, and WF825884 up to 1800 RPM (limited by rear pump).
Selection Guide: For high-speed drive motors, WF825847 is best; for standard speeds, others suffice.
Quick Selection Guide
If you need: Highest total flow and a priority valve for flow management
Choose: WF825841
Because: It offers 19.0 GPM combined flow with a built-in priority valve, ideal for systems needing prioritized hydraulic functions.
If you need: Balanced dual flows for Hi-Lo circuits or equal output sections
Choose: WF825847
Because: Provides two equal 8 GPM sections (total 16.0 GPM) for dual-function circuits.
If you need: Single-section flow for simple hydraulic needs or space-constrained systems
Choose: WF825975, WF825063, or WF825884
Because: Each delivers 10.0 GPM from the front section only; select based on required rotation and port orientation.
If you need: Specific port orientation for ease of plumbing
Choose: WF825847 (90° CW), WF825841 (90° CCW), WF825975/WF825063 (180°), or WF825884 (0°)
Because: Port orientation affects hose routing and installation—choose the model that matches your system layout.
If you need: High RPM capability
Choose: WF825847
Because: Supports up to 2800 RPM, suitable for faster drive applications.
Compatibility: All models are designed for direct Vickers interchangeability and use SAE ‘A’ 2-bolt flange mounting with G1″/G1/2″ BSPP straight thread ports, ensuring easy replacement in existing setups.
