Product Selection Guide
These vane pumps—specifically the FluiDyne V2020 double vane pump models—primarily differ in flow rates, maximum speed, shaft type, port orientation, and rotation direction. All are direct Vickers replacements, fully SAE J744 compliant, and rated for up to 2500 PSI, but their configuration details make each suitable for distinct system requirements.
?? 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 |
|---|---|---|---|---|
| WF825939 (Current) | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825931 | 9 | 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: WF825939 delivers the highest total flow at 18.0 GPM (10 GPM front, 8 GPM rear), while WF825931 provides 14.0 GPM (9 GPM front, 5 GPM rear). All others offer 10.0 GPM with no rear flow.
Selection Guide: Choose WF825939 for applications needing dual flow outputs or higher total flow; select WF825931 for moderate dual flows; use WF825975, WF825063, or WF825884 for single-section 10 GPM needs.
Maximum Speed
Difference: WF825939 supports up to 2500 RPM, WF825931 up to 1800 RPM, and the remaining models max out at 1800 RPM (limited by rear pump).
Selection Guide: Choose WF825939 for equipment operating at higher speeds; for standard operations, any model suffices.
Shaft Type
Difference: WF825939, WF825975, WF825063, and WF825884 use a 13-tooth splined shaft; WF825931 uses a straight keyed shaft.
Selection Guide: Opt for splined shafts (high torque, less wear) in heavy-duty or high-shock applications; use straight keyed shafts for standard couplings.
Rotation Direction
Difference: WF825939, WF825975, and WF825884 are Left-Hand (CCW); WF825931 and WF825063 are Right-Hand (CW).
Selection Guide: Match pump rotation to your drive system—CCW for left-hand, CW for right-hand input.
Port Orientation
Difference: WF825939 and WF825884 feature both outlets inline with the inlet (0°); WF825931 has front outlet opposite (180°), rear at 90° CW; WF825975 and WF825063 have both outlets opposite inlet (180°).
Selection Guide: Select inline ports for streamlined plumbing; use 180° or 90° options for installations with space constraints or specific hose routing.
Quick Selection Guide
If you need: Dual independent flows or highest total flow (18.0 GPM)
Choose: WF825939
Because: Provides both front (10 GPM) and rear (8 GPM) outputs, ideal for Hi-Lo circuits or powering two actuators.
If you need: Moderate dual-flow (9 GPM + 5 GPM) with right-hand rotation and custom port orientations
Choose: WF825931
Because: Offers two separate flows with flexible port positions for specialized system layouts.
If you need: Single 10 GPM output with left-hand rotation and splined shaft
Choose: WF825975 or WF825884
Because: Both models provide 10 GPM (front section only) with robust splined shafts; choose port orientation (inline for WF825884, 180° for WF825975) to fit your plumbing.
If you need: Single 10 GPM output with right-hand rotation
Choose: WF825063
Because: Provides 10 GPM with right-hand rotation for systems requiring clockwise pump input.
Compatibility: All models comply with SAE ‘B’ 4-bolt flange mounting and are 100% interchangeable with Vickers V2020 pumps. Ports use 1-1/16″-12 UN-2B or G-thread straight threads, ensuring seamless replacement.
