Product Selection Guide
These FluiDyne V2020 double vane pump models, such as the V20201F10S10S11AA30L – FluiDyne V2020, are all direct Vickers replacements, but differ primarily in their total flow output, rear pump capacity, rotation direction, port orientation, and maximum speed. Understanding these differences helps match the pump to your system’s flow, space, and rotational requirements.
?? 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 |
|---|---|---|---|---|
| WF8251039 (Current) | 12 | 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
Total Flow Output
Difference: WF8251039 delivers the highest total flow (20.0 GPM), followed by WF8251074 (18.0 GPM), WF8251091 (17.0 GPM), and WF8251014/WF8251052 (14.0 GPM each).
Selection Guide: Select WF8251039 for systems requiring the highest combined flow; choose WF8251014 or WF8251052 for lower flow or precise secondary circuit needs.
Rear Pump Flow Capacity
Difference: WF8251039 and WF8251091 have higher rear pump flows (8 GPM and 6 GPM), whereas WF8251014 and WF8251052 are limited to 2 GPM at the rear section.
Selection Guide: Choose a model with higher rear pump flow (WF8251039, WF8251091, WF8251074) if your secondary circuit requires more hydraulic power. For pumps with additional integrated control, see our pumps with integral valves selection.
Maximum Speed (RPM)
Difference: WF8251091 and WF8251074 allow up to 2500 RPM, WF8251039 up to 2400 RPM, while WF8251014 and WF8251052 are limited to 1800 RPM.
Selection Guide: For higher-speed applications, prefer WF8251091 or WF8251074. Use WF8251014 or WF8251052 where lower speeds are sufficient or required.
Rotation Direction
Difference: WF8251039, WF8251091, and WF8251052 are right-hand (clockwise); WF8251074 and WF8251014 are left-hand (counter-clockwise).
Selection Guide: Match rotation direction to your drive system—select a clockwise model if your system requires right-hand rotation; otherwise use a counter-clockwise model.
Port Orientation
Difference: WF8251039, WF8251074, and WF8251052 have both outlets inline with the inlet (0°). WF8251091 has front outlet at 90° CCW and rear at 180°, while WF8251014 has both outlets opposite the inlet (180°).
Selection Guide: Inline port orientation simplifies straight hose routing; 90° or 180° orientations are suited for installations with space constraints or specific routing needs.
Shaft Type
Difference: WF8251039 and WF8251074 use a 13-tooth splined shaft; WF8251091, WF8251014, and WF8251052 use a straight keyed shaft.
Selection Guide: Choose splined shafts (WF8251039, WF8251074) for high-torque or shock-load applications; straight keyed shafts for standard coupling arrangements.
Quick Selection Guide
If you need: Maximum total flow and high rear pump capacity
Choose: WF8251039
Because: It provides 20.0 GPM total flow and 8 GPM rear pump output, ideal for high-demand dual-circuit systems. For alternative displacement options, consider the V201P5P18C11R – FluiDyne V20 Pump.
If you need: Balanced dual flows with moderate total output and left-hand rotation
Choose: WF8251074
Because: It offers 11 GPM front and 7 GPM rear at up to 2500 RPM, with counter-clockwise rotation and inline ports.
If you need: High speed with different port orientation
Choose: WF8251091
Because: It accommodates up to 2500 RPM and provides 11 GPM front and 6 GPM rear, with unique 90°/180° port orientation for flexible installation.
If you need: Lower total flow and precise secondary circuit with left-hand or right-hand rotation
Choose: WF8251014 (left-hand) or WF8251052 (right-hand)
Because: Both deliver 12 GPM front and 2 GPM rear at up to 1800 RPM, suitable for systems needing minimal secondary flow. For higher displacement applications, see the V201P13P3C11R – FluiDyne V20 Pump.
Compatibility: All models conform to SAE J744 mounting standards with SAE ‘B’ 4-bolt flanges and 1-1/16″-12 UN-2B straight thread ports, ensuring 100% direct interchange with Vickers V2020 pumps and other leading vane pumps.
