Product Selection Guide
These FluiDyne V2020 double vane pump models are all direct Vickers replacements, sharing core SAE ‘A’ mountings, port sizes, and pressure ratings, but differ in flow rate, shaft type, rotation direction, and port orientation. Selecting the right model depends on your required flow, system layout, preferred shaft/coupling, and pump rotation.
?? Important: The specifications shown are for reference and comparison purposes. For a wider range of options, see our hydraulic pumps selection. 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 |
|---|---|---|---|---|
| WF825431 (Current) | 9 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825433 | 12 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825975 | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825063 | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825884 | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Flow Rate
Difference: WF825431 delivers 9 GPM front + 1 GPM rear (10 GPM total); WF825433 delivers 12 GPM front + 1 GPM rear (13 GPM total); WF825975, WF825063, and WF825884 deliver 10 GPM front (rear pump inactive, 10 GPM total).
Selection Guide: Choose WF825433 for highest combined flow (13 GPM); select WF825431 for moderate dual-output applications; pick WF825975, WF825063, or WF825884 for single-output (10 GPM) needs.
Shaft Type
Difference: WF825431 and WF825433 use straight keyed shafts; WF825975, WF825063, and WF825884 use 13-tooth splined shafts.
Selection Guide: Select straight keyed shaft models (WF825431, WF825433) for standard coupling; opt for splined shafts (WF825975, WF825063, WF825884) for higher torque or positive drive coupling.
Rotation Direction
Difference: WF825431, WF825433, and WF825063 are right-hand (clockwise); WF825975 and WF825884 are left-hand (counter-clockwise).
Selection Guide: Choose a right-hand model (WF825431, WF825433, WF825063) if your prime mover turns clockwise; select left-hand (WF825975, WF825884) for counter-clockwise systems.
Port Orientation
Difference: WF825431, WF825433, WF825975, and WF825063 have both outlets opposite inlet (180°); WF825884 has both outlets inline with inlet (0°).
Selection Guide: Use 180° outlet models for systems where lines run opposite the inlet; pick WF825884 (0°) for inline plumbing convenience.
Quick Selection Guide
If you need: Highest flow (13 GPM) with dual outputs and right-hand rotation
Choose: WF825433
Because: It provides the maximum total output in this group with standard coupling.
If you need: Moderate dual-output (10 GPM) and right-hand rotation
Choose: WF825431
Because: It offers balanced flow for systems needing two circuits with same rotation.
If you need: Single-output (10 GPM), left-hand rotation, and splined shaft
Choose: WF825975 or WF825884
Because: Both meet these criteria; WF825884 is preferable for inline port orientation.
If you need: Single-output (10 GPM), right-hand rotation, and splined shaft
Choose: WF825063
Because: It matches clockwise systems needing splined coupling.
Compatibility: All models use SAE ‘A’ 2-bolt flange mounting and G1″/G1/2″ BSPP straight thread ports, and are 100% interchangeable with Vickers V2020-series pumps.
