Product Selection Guide
These five hydraulic pumps in the FluiDyne V2020 double vane pump series are all direct Vickers replacements, sharing the same SAE ‘A’ mounting, pressure ratings, and port sizes, but differ in flow rates, shaft type, rotation direction, port orientation, and design series. Choosing the right model depends on your system’s required flow, preferred rotation, shaft compatibility, and how your hydraulic lines are routed.
?? 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 |
|---|---|---|---|---|
| WF8251107 (Current) | 13 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8251101 | 13 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8251121 | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825111 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825115 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Flow Rate
Difference: Front pump flow rates range from 10 to 13 GPM, with total flows from 12.0 to 15.0 GPM depending on the model.
Selection Guide: Choose WF8251107 or WF8251101 (13 GPM front, 14 GPM total) for higher flow demands. Select WF8251121 (10 GPM front, 15 GPM total) if your system requires more balanced dual outputs. WF825111 and WF825115 (11 GPM front, 12 GPM total) suit moderate-flow systems.
Rotation Direction
Difference: Models are available in both right-hand (clockwise) and left-hand (counter-clockwise) rotation.
Selection Guide: Choose WF8251107, WF8251101, or WF825115 for right-hand rotation systems. Select WF8251121 or WF825111 for left-hand rotation requirements.
Port Orientation
Difference: Outlet port orientation varies: both inline with inlet (0°), both opposite inlet (180°), or both 90° CW from inlet.
Selection Guide: Select inline (WF8251107, WF8251101) for straightforward line runs; 180° (WF8251121, WF825111) for opposite-facing connections; 90° CW (WF825115) when mounting space or hose routing requires a side exit.
Shaft Type
Difference: Models are equipped with either a 13-tooth splined shaft or a straight keyed shaft.
Selection Guide: Choose a 13-tooth splined shaft (WF8251107, WF8251101, WF825111, WF825115) — or see other FluiDyne models with similar specs for higher torque and robust coupling; select straight keyed shaft (WF8251121) for compatibility with existing keyed couplings.
Design Series
Difference: Available in different design series (11, 12, or 30), which may affect internal updates or interchangeability with specific Vickers generations. If you need pumps with additional features, view our pumps with integral valves lineup.
Selection Guide: Match design series if replacing an existing pump to ensure perfect fit and function.
Quick Selection Guide
If you need: Highest front section flow (13 GPM) and right-hand rotation
Choose: WF8251107 or WF8251101
Because: These models offer the maximum front pump flow and support straightforward port orientation for common hydraulic layouts. For other high-flow applications, see FluiDyne V20 models with similar application ratings.
If you need: Balanced dual flows and left-hand rotation
Choose: WF8251121
Because: It provides a higher rear pump (5 GPM) for applications needing two significant flows.
If you need: Moderate flow with left-hand rotation and 180° port orientation
Choose: WF825111
Because: Best for systems requiring both outlets opposite the inlet and a left-hand rotating shaft.
If you need: Moderate flow with right-hand rotation and 90° outlet orientation
Choose: WF825115
Because: Ideal for right-hand systems needing side (90°) port exit for tight or angled installations.
Compatibility: All models are 100% interchangeable with Vickers replacement pumps, following SAE J744 and using G1″/G1/2″ BSPP straight thread ports. Same-day shipping is available for in-stock units, with volume pricing starting at 4 units and a 12-month warranty.
