Product Selection Guide
These five FluiDyne V2020 double vane pump models are all direct Vickers replacements, but differ in their front and rear pump flow rates, total output, port orientation, rotation, and shaft type. Selecting the right model depends on your system’s required total flow, configuration constraints, and direction of rotation. For similar output and compact installations, consider the V201P5P18C11R – FluiDyne V20 Pump.
?? 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 |
|---|---|---|---|---|
| WF8251054 (Current) | 9 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8251091 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8251074 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8251014 | 12 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8251052 | 12 | 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: WF8251054 and WF8251074 both offer 18.0 GPM total flow (WF8251054: 9+9 GPM; WF8251074: 11+7 GPM). WF8251091 provides 17.0 GPM (11+6 GPM). WF8251014 and WF8251052 provide lower total flow at 14.0 GPM (12+2 GPM).
Selection Guide: Choose WF8251054 or WF8251074 for higher-demand circuits needing balanced or higher output; WF8251014 or WF8251052 for applications where lower total flow suffices or where a small secondary flow is needed.
Maximum Speed
Difference: WF8251054 and WF8251074 can operate up to 2800/2500 RPM, supporting higher-speed systems. WF8251014 and WF8251052 are limited to 1800 RPM due to their low-flow rear stage.
Selection Guide: Select higher-RPM models (WF8251054, WF8251074, WF8251091) for systems with rapid cycling or where high shaft speed is required.
Port Orientation
Difference: WF8251054 and WF8251074 have both outlets inline with inlet (0°). WF8251091 has front outlet at 90° CCW and rear at 180°. WF8251014 has both outlets opposite inlet (180°). WF8251052 has both outlets inline (0°).
Selection Guide: Choose inline (0°) for straightforward plumbing; 90°/180° models (WF8251091, WF8251014) where offset connections simplify installation in compact or restrictive layouts.
Rotation Direction
Difference: WF8251054, WF8251074, and WF8251014 are left-hand (CCW), while WF8251091 and WF8251052 are right-hand (CW).
Selection Guide: Match rotation to your drive motor—select left-hand models for CCW drives and right-hand for CW drives.
Shaft Type
Difference: WF8251074 offers a 13-tooth splined shaft for higher torque applications, while others use straight keyed shafts.
Selection Guide: Choose splined shaft (WF8251074) if your system transmits higher torque or uses splined couplings. For larger displacement needs, see V201P13P3A11R – FluiDyne V20 Pump.
Quick Selection Guide
If you need: Highest total flow (18.0 GPM) with balanced front and rear pump outputs
Choose: WF8251054
Because: Both sections deliver 9 GPM at up to 2800 RPM, ideal for dual high-demand circuits.
If you need: High total flow (18.0 GPM) with more flow in the front section and a splined shaft for high torque
Choose: WF8251074
Because: Front pump provides 11 GPM, rear 7 GPM, and the 13-tooth splined shaft suits high-torque drives.
If you need: High front flow (11 GPM) and moderate rear flow (6 GPM) with offset port orientation
Choose: WF8251091
Because: Port configuration (90°/180°) fits compact installations and right-hand rotation matches CW drives.
If you need: Lower total flow (14.0 GPM) with a dominant main circuit and left-hand rotation
Choose: WF8251014
Because: Front pump offers 12 GPM, rear 2 GPM, and both outlets are opposite the inlet for unique setups.
If you need: Lower total flow (14.0 GPM) with right-hand rotation and inline port orientation
Choose: WF8251052
Because: Suitable for low-flow secondary circuits and applications needing CW rotation.
Compatibility: All models are 100% interchangeable with Vickers equivalents, use SAE ‘B’ 4-bolt mounting and standardized G1″/G1/2″ BSPP port threads, and meet SAE J744 standards for easy retrofit. For more Vickers alternatives, browse our Vickers replacement pumps category.
