Product Selection Guide
These FluiDyne V2020 double vane pump models differ primarily in their flow rates, port orientations, pump rotations, and maximum speeds. All models are direct Vickers replacements, mount with SAE ‘B’ 4-bolt flanges, and support up to 2500 PSI. For specialized needs, review our selection of single stage vane pumps as alternatives. Model selection should focus on required flow, rotation direction, speed limits, and port layout for the hydraulic system.
?? 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 |
|---|---|---|---|---|
| WF825579 (Current) | 9 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825577 | 13 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825574 | 5 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| V20201F10S10S11AA30L – FluiDyne V2020 (19.5 cm³/r (1.19 in³/r)) | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |

Key Differences
Total Flow Rate (GPM)
Difference: WF825577 delivers the highest total flow at 20.0 GPM; WF825579 provides 15.0 GPM; WF825975, WF825063, and WF825574 each offer 10.0 GPM.
Selection Guide: Choose WF825577 for systems needing the most oil delivery; WF825579 for moderate flow; WF825975, WF825063, or WF825574 for lower flow applications or where reduced pump loads are required.
Pump Rotation
Difference: WF825577 and WF825574 rotate right-hand (clockwise); WF825579 and WF825975 are left-hand (counter-clockwise); WF825063 is right-hand.
Selection Guide: Match pump rotation to your existing drive motor and system requirements. Left-hand models (WF825579, WF825975) are for counter-clockwise drives; right-hand models (WF825577, WF825063, WF825574) for clockwise drives.
Maximum Speed (RPM)
Difference: WF825579 allows up to 2800 RPM; WF825577 up to 2400 RPM; WF825574, WF825975, and WF825063 up to 1800 RPM.
Selection Guide: For applications with higher drive speeds, select WF825579. Avoid exceeding max RPM to prevent premature wear.
Front and Rear Pump Sizing
Difference: WF825577 offers the largest front pump (13 GPM) and rear pump (7 GPM); WF825579 is 9/6 GPM; WF825574 is balanced 5/5 GPM; WF825975 and WF825063 are single-stage (front pump only, 10 GPM).
Selection Guide: Select models with dual flow sections (WF825577, WF825579, WF825574) for hi-lo circuits or multiple actuators. For single flow, WF825975 and WF825063 provide just the front pump output. If your application requires built-in controls, explore our pumps with integral valves.
Port Orientation
Difference: WF825579, WF825975, and WF825063 have outlets opposite the inlet (180°); WF825577 and WF825574 have outlets inline with the inlet (0°).
Selection Guide: Choose 180° porting for opposite-side connections and 0° for same-side plumbing—essential for fitting pump into existing piping layouts.
Shaft Type
Difference: WF825579, WF825577, WF825975, and WF825063 have 13-tooth splined shafts; WF825574 has a straight keyed shaft.
Selection Guide: Use splined shafts for high-torque or vibration-prone applications; keyed shafts are standard for general use.
Quick Selection Guide
If you need: The highest flow rate with dual outputs for two circuits
Choose: WF825577
Because: It provides 13 GPM (front) and 7 GPM (rear), supporting a total of 20.0 GPM for demanding multi-function systems.
If you need: Moderate flow with higher speed capability and left-hand rotation
Choose: WF825579
Because: It offers 15.0 GPM total, left-hand rotation, and a 2800 RPM limit—ideal for faster drives and counter-clockwise configurations.
If you need: Balanced low-flow outputs for compact or low-demand systems
Choose: WF825574
Because: It provides 5/5 GPM at up to 1800 RPM, with a right-hand rotation and straight keyed shaft for simple, space-saving installations.
If you need: A single-output (front only) pump with left-hand rotation
Choose: WF825975
Because: It delivers 10 GPM front output only, suited for systems where only one circuit is needed with counter-clockwise drive.
If you need: A single-output (front only) pump with right-hand rotation
Choose: WF825063
Because: It matches the above, but for clockwise drives.
