Product Selection Guide
These FluiDyne V2020 double vane pump models are all direct Vickers replacements with 100% interchangeability (see additional pumps with integral valves), but differ mainly in combined flow rates, port orientations, shaft types, rotation directions, and total displacement. All models share the same SAE ‘B’ 4-bolt mounting pattern, pressure rating (2500 PSI), and most port specifications, but are tailored for different hydraulic circuit 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 |
|---|---|---|---|---|
| WF8251074 (Current) | 11 | 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) |
| 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) |
| WF8251040 | 12 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Flow Rate & Total Displacement
Difference: Total flow ranges from 14.0 GPM (WF8251014, WF8251052) to 20.0 GPM (WF8251040); total displacement from 3.41 cu.in./rev to 4.08 cu.in./rev.
Selection Guide: Select higher total flow/displacement models like WF8251040 for larger actuators or higher system demand—or compare with our high-displacement V20 pumps for demanding circuits.
Front/Rear Pump Flows
Difference: Front pumps deliver 11 or 12 GPM; rear pumps range from 2 GPM (WF8251014, WF8251052) to 8 GPM (WF8251040).
Selection Guide: Choose a high rear pump GPM (e.g., WF8251040 rear: 8 GPM) for circuits needing simultaneous multi-function flows.
Maximum Speed (RPM)
Difference: WF8251040 supports up to 2400 RPM; WF8251074/1091 up to 2500 RPM; WF8251014/1052 limited to 1800 RPM.
Selection Guide: Select higher RPM-capable models for use with faster prime movers or where high-speed operation is needed.
Shaft Type
Difference: WF8251074 and WF8251040 use 13-tooth splined shafts; WF8251014 and WF8251052 use straight keyed shafts.
Selection Guide: Choose splined shaft models for high-torque applications or where positive engagement is required.
Rotation Direction
Difference: WF8251074, WF8251014, WF8251040: Left-Hand (CCW); WF8251091, WF8251052: Right-Hand (CW).
Selection Guide: Match pump rotation to your drive system. For clockwise (CW) drives, select WF8251091 or WF8251052.
Port Orientation
Difference: WF8251074 and WF8251040: both outlets inline with inlet (0°); WF8251014: both outlets opposite inlet (180°); WF8251091: front outlet 90° CCW, rear outlet opposite (180°); WF8251052: both outlets inline (0°).
Selection Guide: Select port orientation that best matches your piping layout for easier installation.
Quick Selection Guide
If you need: Highest total flow for demanding systems (20.0 GPM)
Choose: WF8251040
Because: It delivers the highest combined flow (12 + 8 GPM) and displacement (4.08 cu.in./rev), suitable for larger or multiple actuators.
If you need: Balanced dual flows with left-hand rotation
Choose: WF8251074
Because: Offers 11 + 7 GPM with both outlets inline (0°) and left-hand rotation—ideal for parallel circuit needs.
If you need: Similar output as WF8251074 but right-hand rotation or unique port orientation
Choose: WF8251091
Because: Provides 11 + 6 GPM, right-hand rotation, and distinct port orientation (front: 90° CCW, rear: 180°).
If you need: Lower total flow with minimal rear pump output (2 GPM) and left-hand rotation
Choose: WF8251014
Because: Best for systems requiring primary flow with a small secondary circuit, both outlets opposite inlet (180°).
If you need: Lower total flow with minimal rear pump output (2 GPM) and right-hand rotation
Choose: WF8251052
Because: Matches above, but with right-hand rotation and both outlets inline (0°).
Compatibility: All models are direct Vickers replacements, meet SAE J744 mounting standards (SAE ‘B’ 4-bolt), and use standard port sizes for straightforward interchangeability. For more details, view our vane pumps selection applications page.
