Product Selection Guide
These FluiDyne V2020 double vane pump models primarily differ in flow rate, outlet port orientation, shaft type, rotation direction, mounting flange style, and whether a priority valve cover is included. For applications requiring integrated flow controls, consider our pumps with integral valves. All are direct Vickers replacements and fully interchangeable, but their specific configurations make them better suited to different hydraulic circuit requirements and installation constraints.
?? 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 |
|---|---|---|---|---|
| WF825991 (Current) | 6 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825995 | 6 | 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) |

Key Differences
Flow Rate & Displacement
Difference: WF825991 and WF825995 provide a combined flow of 12.0 GPM (6 GPM per section), while WF825975, WF825063, and WF825884 provide 10.0 GPM (only front section active). All have 1.19 in³/rev displacement per section.
Selection Guide: Choose WF825991 or WF825995 for applications needing dual flows or a total of 12 GPM; choose WF825975, WF825063, or WF825884 for single-section operation with 10 GPM flow.
Port Orientation
Difference: WF825991 and WF825884 have inline outlets (0°), whereas WF825995, WF825975, and WF825063 have outlets opposite the inlet (180°).
Selection Guide: Select inline port models (WF825991, WF825884) for simpler straight-through plumbing; use opposite port models where space or hose routing requires.
Shaft Type
Difference: WF825991 uses a 3/4″ straight keyed shaft; WF825995, WF825975, WF825063, and WF825884 use a 13-tooth splined shaft.
Selection Guide: Choose splined shaft models for higher torque and coupling reliability, especially in demanding or continuous-duty cycles. See also V201P5P18C11R – FluiDyne V20 Pump for models with similar performance characteristics.
Rotation Direction
Difference: WF825991, WF825063: Right-hand (clockwise); WF825975, WF825884: Left-hand (counter-clockwise).
Selection Guide: Select the rotation that matches your drive motor or system requirements.
Mounting Flange
Difference: WF825991: SAE ‘A’ 2-bolt flange; WF825995, WF825975, WF825063, WF825884: SAE ‘B’ 4-bolt flange.
Selection Guide: Match the mounting flange to your equipment’s pump pad or adapter.
Priority Valve Cover
Difference: Only WF825995 includes a priority valve cover, enabling flow prioritization to specific circuits.
Selection Guide: Choose WF825995 if your system requires dedicated flow to steering or priority circuits.
Speed Limitation
Difference: WF825991 and WF825995: Max 3400 RPM (front pump limit); all others: Max 1800 RPM (rear pump limit).
Selection Guide: Choose higher RPM models (WF825991, WF825995) for faster system cycling or when driven by high-speed motors.
Quick Selection Guide
If you need: Equal dual flows at 6 GPM each (total 12 GPM), right-hand rotation, SAE ‘A’ 2-bolt mounting, and straight keyed shaft
Choose: WF825991
Because: It provides two active V20 sections with inline outlets and is suitable for applications requiring compact, balanced flow in both sections.
If you need: 12 GPM dual-section pump with flow prioritization (e.g., for steering circuit), priority valve cover, splined shaft, and opposite port orientation
Choose: WF825995
Because: It offers built-in priority flow, higher RPM capacity, and heavy-duty splined shaft.
If you need: 10 GPM single-section operation (front only), left-hand rotation, SAE ‘B’ 4-bolt mounting, and splined shaft with inline ports
Choose: WF825884
Because: Provides single active section output, suitable for applications with left-hand drive and in-line plumbing.
If you need: 10 GPM single-section operation (front only), right-hand rotation, SAE ‘B’ 4-bolt mounting, and splined shaft with opposite ports
Choose: WF825063
Because: Delivers right-hand rotation and is ideal for systems needing opposite port orientation.
If you need: 10 GPM single-section operation (front only), left-hand rotation, SAE ‘B’ 4-bolt mounting, and splined shaft with opposite ports
Choose: WF825975
Because: Suited for left-hand drive systems with opposite port orientation.
Compatibility: All models are 100% interchangeable with their Vickers equivalents and meet SAE J744 mounting standards, ensuring seamless fit with existing systems. Discover more hydraulic pump options for your hydraulic circuit needs. They use G1″ and G1/2″ BSPP straight thread ports for consistent plumbing across models.
