Important: Verify pump model WF8251115 matches your existing Vickers unit before ordering. For a full range of hydraulic pumps, explore our product family. For technical assistance or to confirm interchangeability, contact (800) 823-4937.
Product Selection Guide
The provided FluiDyne V2020 double vane pump models (see single stage vane pumps for comparison) differ primarily in their total flow rates, front/rear pump GPM combinations, port orientations, shaft types, rotation direction, and allowable maximum speeds. These differences directly impact system performance, installation layout, and compatibility with existing hydraulic circuits.
?? 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 |
|---|---|---|---|---|
| WF8251115 (Current) | 12 | 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
Total Flow Rate
Difference: WF8251115 delivers the highest total flow at 20.0 GPM, followed by WF825116 at 19.0 GPM, WF8251121 at 15.0 GPM, and WF825111/WF825115 at 12.0 GPM.
Selection Guide: Select WF8251115 or WF825116 for systems needing higher combined pump flows; WF825111 or WF825115 for lower flow or more precise control.
Front/Rear Pump Output
Difference: WF8251115 offers 12 GPM (front) + 8 GPM (rear); WF825116: 11 GPM + 8 GPM; WF8251121: 10 GPM + 5 GPM; WF825111/WF825115: 11 GPM + 1 GPM.
Selection Guide: Choose models with higher rear GPM (WF8251115, WF825116) for dual-circuit or Hi-Lo applications needing more secondary flow. For different displacement needs, see V201P13P3C11R – FluiDyne V20 Pump.
Maximum Speed
Difference: WF825116 allows up to 2500 RPM; WF8251115 up to 2400 RPM; WF8251121, WF825111, and WF825115 limited to 1800 RPM.
Selection Guide: Select WF825116 for higher-speed applications; for 18.0 cm³/r options, see V201P5P18C11R – FluiDyne V20 Pump. Avoid WF8251121, WF825111, and WF825115 if your drive runs above 1800 RPM.
Port Orientation
Difference: WF8251115 and WF825111: both outlets opposite inlet (180°); WF8251121: front 180°, rear inline (0°); WF825115: both 90° CW from inlet; WF825116: both 90° CCW from inlet.
Selection Guide: Choose port orientation based on your plumbing layout—180° for straight runs, 90° for compact or side-exit connections. Explore pumps with integral valves for specialized configurations.
Rotation Direction
Difference: WF8251115, WF8251121, WF825111: Left-Hand (CCW); WF825115, WF825116: Right-Hand (CW).
Selection Guide: Match rotation to your drive—left-hand for CCW motors, right-hand for CW.
Shaft Type
Difference: WF8251115, WF8251121: Straight Keyed Shaft; WF825111, WF825115: 13-Tooth Splined Shaft; WF825116: Shaft code 51 (type not further specified).
Selection Guide: Use straight keyed shafts for standard couplings; select splined for higher torque or specialized couplings.
Quick Selection Guide
If you need: Highest total flow (20.0 GPM), left-hand rotation, and both outlets opposite inlet
Choose: WF8251115
Because: It maximizes dual-circuit output and fits standard 180° plumbing with a straight keyed shaft.
If you need: High flow (19.0 GPM), right-hand rotation, and 90° CCW outlet ports
Choose: WF825116
Because: It supports higher speeds and 90° porting for compact installation.
If you need: Moderate flow (15.0 GPM), left-hand rotation, with mixed port orientation
Choose: WF8251121
Because: It offers a dual-circuit split with flexible plumbing for specific system layouts.
If you need: Low rear section flow (1 GPM), left-hand rotation, and 180° porting
Choose: WF825111
Because: Ideal for applications with minimal secondary circuit requirements. For alternative flow profiles, see similar applications in other double vane series.
If you need: Low rear section flow (1 GPM), right-hand rotation, and 90° CW porting
Choose: WF825115
Because: Best for low secondary flow needs and right-hand drive motors in tight installations.
Compatibility: All models use SAE ‘B’ 4-bolt flange mounting and 1-1/16″-12 UN-2B thread outlets for direct Vickers replacement pumps interchangeability. They meet SAE J744 standards and accept G1″/G1/2″ BSPP ports for straightforward replacement.
