Product Selection Guide
These FluiDyne V2020F double vane pump models are all direct Vickers replacements, designed for dual-flow hydraulic applications. The main differences lie in their total flow output, pressure settings, rear pump size, shaft type, port orientation, and rotation direction. All models feature SAE mounting for direct compatibility and are suitable for medium- to high-pressure circuits up to 2500 PSI.
?? 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 |

Key Differences
Total Flow Output
Difference: WF825444 provides 16.0 GPM (Front: 13 GPM, Rear: 3 GPM), WF825553, WF825535, and WF825922 provide 12.0 GPM (Front: 11 GPM, Rear: 1 GPM), while WF825986 delivers 20.0 GPM (Front: 11 GPM, Rear: 9 GPM).
Selection Guide: Select WF825986 for the highest total flow (20.0 GPM), WF825444 when a moderate rear flow (3 GPM) is needed, or the 12 GPM models (WF825553/WF825535/WF825922) for low combined flow.
Rear Pump Capacity
Difference: WF825444: 3 GPM; WF825553/535/922: 1 GPM; WF825986: 9 GPM.
Selection Guide: Choose WF825986 if your circuit requires significant secondary flow (9 GPM rear), or WF825553/535/922 for minimal secondary flow (1 GPM rear).
Pressure Setting
Difference: WF825444 & WF825553: 1000 PSI; WF825535: 1500 PSI; WF825922: 1750 PSI; WF825986: 2500 PSI.
Selection Guide: Opt for WF825986 if you need the highest pressure (2500 PSI), or the others for medium pressure applications as specified.
Maximum Speed (RPM)
Difference: WF825444, WF825553, WF825535, WF825922: 1800 RPM (limited by rear pump); WF825986: 2500 RPM (limited by front pump).
Selection Guide: WF825986 supports higher-speed applications (up to 2500 RPM); others are limited to 1800 RPM.
Shaft Type
Difference: WF825444, WF825553: 13-tooth splined shaft; WF825535, WF825922, WF825986: straight keyed shaft.
Selection Guide: Splined shafts (WF825444, WF825553) are recommended for higher-torque needs or when using splined couplings.
Port Orientation
Difference: WF825444: Both outlets 90° CCW from inlet; WF825553/986: Both outlets 90° CW from inlet; WF825535/922: Front outlet 90° CCW, rear outlet inline (0°).
Selection Guide: Choose models with matching port orientation to your system piping—90° positions are ideal for tight spaces, inline for direct runs.
Rotation Direction
Difference: WF825444, WF825553, WF825535, WF825922: Left-Hand (CCW); WF825986: Right-Hand (CW).
Selection Guide: Verify your drive motor direction—select CCW models for left-hand drive, WF825986 for right-hand (CW) systems.
Quick Selection Guide
If you need: Highest total flow and pressure (20 GPM, 2500 PSI) with fast system response
Choose: WF825986
Because: It provides the largest rear pump (9 GPM), highest speed (2500 RPM), and maximum pressure.
If you need: Moderate total flow with greater front section output (13 GPM front, 3 GPM rear)
Choose: WF825444
Because: This model is balanced for circuits needing a larger primary flow and a moderate secondary flow.
If you need: Low total flow for compact circuits or low auxiliary flow (1 GPM rear)
Choose: WF825553, WF825535, or WF825922
Because: They are best for applications with minimal secondary demand or where space and energy efficiency are priorities.
If you need: Specific pressure requirements (1000, 1500, 1750 PSI)
Choose: WF825553 for 1000 PSI, WF825535 for 1500 PSI, WF825922 for 1750 PSI
Because: Each model matches a specific system pressure limit.
If you need: Splined shaft for high-torque coupling
Choose: WF825444 or WF825553
Because: Both feature a 13-tooth splined shaft for improved torque transmission.
If you need: Right-hand rotation (clockwise drive)
Choose: WF825986
Because: It is the only model with right-hand (CW) rotation.
Compatibility: All models maintain 100% direct interchangeability with Vickers pumps, use SAE B 4-bolt mounting, and feature standardized port sizes for seamless system integration. Volume pricing starts at 4 units and each pump is backed by a 12-month manufacturer warranty. Same-day shipping is available on in-stock items.
