Product Selection Guide
These FluiDyne V2020 double vane pump models primarily differ in their front and rear pump flow rates, shaft type, port orientation, rotation direction, and maximum allowable speed. Each model’s configuration makes it better suited for particular hydraulic system requirements, such as total GPM needs, plumbing layout, or shaft/coupling compatibility. For more on single stage options, see our single stage vane pumps section. All models feature direct Vickers interchangeability, SAE mounting, and 2500 PSI max pressure, ensuring easy replacement and robust performance.
?? Important: The specifications shown are for reference and comparison purposes. For additional technical details, see our hydraulic pumps overview. 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 |
|---|---|---|---|---|
| WF8251125 (Current) | 9 | 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) |
| WF825116 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Front and Rear Pump Flow Rates
Difference: Front pumps range from 9 to 11 GPM; rear pumps from 1 to 8 GPM; total combined flow ranges from 12.0 to 19.0 GPM.
Selection Guide: Select WF825116 for the highest total flow (19.0 GPM, 11 GPM front + 8 GPM rear). For different displacement needs, see the V201P5P18C11R Fluidyne V20 Pump for 18.0 cm³/r (1.10 in³/r) configurations. Choose WF8251125 or WF8251121 for moderate flows (14–15 GPM), or WF825111/WF825115 for lower combined flows (12.0 GPM) when fine control or smaller actuators are needed.
Maximum Speed (RPM)
Difference: WF825116 supports up to 2500 RPM; all others are limited to 1800 RPM (by rear pump).
Selection Guide: Choose WF825116 if your system operates at or requires higher pump speeds (above 1800 RPM).
Shaft Type
Difference: WF825111 and WF825115 use a 13-tooth splined shaft; other models use a straight keyed shaft.
Selection Guide: Select splined shaft models (WF825111, WF825115) for high-torque applications or when your coupling requires a splined input. Choose straight keyed for standard coupling compatibility.
Port Orientation
Difference: WF8251125: both outlets inline with inlet (0°); WF8251121: front outlet opposite (180°), rear inline; WF825111: both outlets opposite inlet (180°); WF825115: both outlets 90° CW from inlet; WF825116: both outlets 90° CCW from inlet.
Selection Guide: Choose port orientation to match your system’s plumbing. Inline (0°) suits direct, straight runs; 90° or 180° arrangements help in tight or multi-directional layouts. For pumps with integrated valve options, browse our pumps with integral valves category.
Rotation Direction
Difference: WF8251125, WF825115, WF825116 are right-hand (clockwise); WF8251121, WF825111 are left-hand (counter-clockwise).
Selection Guide: Match the pump rotation to your drive motor or engine. Do not mix rotation directions or you risk pump failure.
Quick Selection Guide
If you need: Highest total flow and RPM capability
Choose: WF825116
Because: Delivers up to 19.0 GPM and supports speeds up to 2500 RPM, ideal for high-demand or fast-cycling systems.
If you need: Moderate total flow with right-hand rotation and inline ports
Choose: WF8251125
Because: Provides 14.0 GPM with both outlets inline and right-hand rotation, simplifying plumbing for many replacements.
If you need: Moderate total flow with left-hand rotation and split port orientation
Choose: WF8251121
Because: Provides 15.0 GPM; front outlet opposite inlet, rear outlet inline, and left-hand rotation for specific mounting needs.
If you need: Lower total flow with splined shaft and left-hand rotation
Choose: WF825111
Because: Delivers 12.0 GPM, features a 13-tooth splined shaft, and both outlets opposite inlet for specialized applications.
If you need: Lower total flow with splined shaft and right-hand rotation
Choose: WF825115
Because: Delivers 12.0 GPM, 13-tooth splined shaft, both outlets 90° CW from inlet, matching certain space or connection constraints.
Compatibility: All models follow SAE ‘A’ size 2-bolt flange mounting and use G1″ BSPP (inlet) and G1/2″ BSPP (outlet) straight thread ports, ensuring direct Vickers replacement and easy integration into existing Vickers replacement pumps applications systems.
