Important: Verify pump model WF8251121 matches your existing Vickers unit before ordering. For technical assistance, contact (800) 823-4937.
Product Selection Guide
These FluiDyne V2020 double vane pumps are all direct Vickers replacements with standardized SAE ‘A’ mounting and similar pressure ratings, but differ primarily in total flow rate, front/rear pump combinations, shaft type, port orientation, and rotation direction. Selecting the right model depends on required flow, space/layout constraints, and drive/rotation needs.
?? 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 |
|---|---|---|---|---|
| WF8251121 (Current) | 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
Total Flow Rate
Difference: WF8251121 provides 15.0 GPM, WF825111 and WF825115 deliver 12.0 GPM, WF825116 offers 19.0 GPM, and WF8251115 supplies the highest at 20.0 GPM.
Selection Guide: Choose higher GPM models (WF825116 or WF8251115) for demanding systems with multiple actuators or high-speed requirements; select lower GPM models (WF825111, WF825115) for precise control or smaller circuits.
Front/Rear Pump Flow Splits
Difference: WF8251121: 10/5 GPM, WF825111/115/116: 11/1 or 11/8 GPM, WF8251115: 12/8 GPM.
Selection Guide: Match the pump’s front/rear flow to your system’s dual-circuit needs—e.g., larger difference (WF8251121: 10/5; WF825111/115: 11/1) for priority circuits, more balanced flow (WF825116: 11/8; WF8251115: 12/8) for dual high-demand circuits.
Maximum Speed
Difference: WF8251121, WF825111, WF825115: 1800 RPM max; WF825116: 2500 RPM max; WF8251115: 2400 RPM max.
Selection Guide: Select WF825116 or WF8251115 for applications with faster drive speeds, while others suit standard 1800 RPM drives.
Rotation Direction
Difference: WF8251121, WF825111, WF8251115: Left-Hand (CCW); WF825115, WF825116: Right-Hand (CW).
Selection Guide: Match pump rotation to your drive motor—choose left-hand for CCW, right-hand for CW rotation.
Shaft Type
Difference: WF8251121, WF8251115: Straight Keyed Shaft; WF825111, WF825115: 13-Tooth Splined Shaft; WF825116: Shaft code 51 (specify if unique coupling).
Selection Guide: Choose splined for high-torque or flexible couplings; straight keyed for standard installations.
Port Orientation
Difference: WF8251121, WF8251115: Both outlets opposite inlet (180°); WF825111: Both outlets opposite inlet (180°); WF825115: Both outlets 90° CW from inlet; WF825116: Both outlets 90° CCW from inlet.
Selection Guide: 180° orientation simplifies straight-line plumbing; 90° options (WF825115/116) are ideal for tight or side-access spaces.
Quick Selection Guide
If you need: Balanced, high dual-circuit flow (e.g., two actuators moving simultaneously)
Choose: WF8251115 (12/8 GPM, 20 GPM total, max 2400 RPM, left-hand rotation, straight keyed shaft)
Because: Offers the highest total flow and balanced distribution, suitable for dual high-demand operations.
If you need: Higher rear section flow with high RPM capability
Choose: WF825116 (11/8 GPM, 19 GPM total, max 2500 RPM, right-hand rotation, shaft code 51)
Because: Handles higher speeds and provides strong flow for both circuits.
If you need: Priority to a large primary circuit, minimal secondary flow
Choose: WF825111 or WF825115 (11/1 GPM, 12 GPM total, max 1800 RPM)
Because: Delivers nearly all flow to the front section, ideal for Hi-Lo circuits or single-actuator systems with auxiliary needs.
If you need: Standard flow split with moderate total flow and left-hand rotation
Choose: WF8251121 (10/5 GPM, 15 GPM total, max 1800 RPM, straight keyed shaft)
Because: Good for applications needing modest dual flows with standard left-hand drive.
If you need: Specific port orientation for plumbing constraints
Choose: WF825115 (90° CW outlets) or WF825116 (90° CCW outlets)
Because: Allows integration into systems with side or corner access requirements.
Compatibility: All models feature SAE ‘A’ 2-bolt flange mounting and G1″/G1/2″ BSPP ports, and are 100% interchangeable with Vickers equivalents for easy system integration.
