Product Selection Guide
These FluiDyne V2020 double vane pumps differ mainly in their flow capacities, outlet port orientations, rotation directions, and priority valve configurations. All models support up to 2500 PSI and offer direct Vickers interchangeability. For applications requiring single circuit operation, see our single stage vane pumps. The division of flow between front and rear pump sections, as well as port and shaft details, will determine the best fit for specific hydraulic system layouts or functions.
?? 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 |
|---|---|---|---|---|
| WF825663 (Current) | 6 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825666 | 8 | 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) |

Key Differences
Total Flow Rate
Difference: WF825663 delivers a combined 12.0 GPM (6+6), while WF825666 provides 9.0 GPM (8+1), and WF825975, WF825063, and WF825884 each provide 10.0 GPM (10+0).
Selection Guide: Select WF825663 for balanced dual flows (6+6 GPM), WF825666 if you need a high-priority circuit (8+1 GPM), and WF825975, WF825063, or WF825884 for single high-flow (10 GPM) from the front pump.
Front vs Rear Pump Flow
Difference: WF825663 splits flow evenly between two outputs (6 GPM each). WF825666 prioritizes the front (8 GPM) with minimal rear (1 GPM). Others (WF825975, WF825063, WF825884) output only from the front (10 GPM front, 0 GPM rear).
Selection Guide: Choose WF825663 for circuits needing two equal flows; WF825666 for Hi-Lo circuits needing a strong main flow and a small secondary flow; others for single-circuit high flow.
Port Orientation
Difference: WF825663: both outlets 90° CW from inlet; WF825666: front 90° CCW, rear 90° CW; WF825975: both outlets 180° from inlet; WF825063: both outlets 180° from inlet; WF825884: both outlets inline (0°) with inlet.
Selection Guide: Select port orientation to match piping constraints. Use WF825884 for straight-line connections, WF825663 for 90° turns, and WF825975/WF825063 for opposite-side piping.
Rotation Direction
Difference: WF825663, WF825666, WF825975, WF825884 are left-hand (CCW); WF825063 is right-hand (CW).
Selection Guide: Choose based on your prime mover’s rotation. Match right-hand pumps to CW drive shafts and left-hand to CCW.
Maximum Speed
Difference: WF825663: up to 3400 RPM; WF825666: 1800 RPM; WF825975, WF825063, WF825884: 1800 RPM.
Selection Guide: WF825663 is suitable for higher-speed applications (up to 3400 RPM); others are limited to 1800 RPM.
Valve Cover/Configuration
Difference: WF825666 includes a priority valve cover, supporting pressure prioritization between circuits. For more options, see our pumps with integral valves; others are standard double pumps.
Selection Guide: Use WF825666 when a priority flow and secondary circuit are required (e.g., steering plus auxiliary).
Shaft Type
Difference: All listed as 13-tooth splined shaft in descriptions; additional spec sheets mention 3/4″ straight keyed shaft. Confirm shaft type per model and required coupling.
Selection Guide: Use splined shafts for high-torque needs; match coupling type to your drive. For similar shaft configurations, review V201P5P18C11R – FluiDyne V20 Pump options.
Quick Selection Guide
If you need: Two equal flows for dual circuits (e.g., twin actuators)
Choose: WF825663
Because: Delivers 6 GPM from each pump section with 3400 RPM max speed.
If you need: Hi-Lo circuit with priority flow (e.g., steering & auxiliary)
Choose: WF825666
Because: Provides an 8 GPM priority flow and 1 GPM secondary, with built-in priority valve.
If you need: Single high-flow output with 10 GPM, specific port orientation, or rotation
Choose: WF825975 (LH, 180° outlets), WF825063 (RH, 180° outlets), or WF825884 (LH, inline/0° outlets)
Because: These models offer 10 GPM from the front pump; for similar applications, see V201P13P40C11R – FluiDyne V20 Pump. Select based on port location and drive rotation.
If you need: Higher operating RPM (up to 3400)
Choose: WF825663
Because: This model supports the highest input speed among the group.
Compatibility: All models feature SAE ‘A’ 2-bolt flange mounting and G1″/G1/2″ BSPP straight thread ports, and are fully interchangeable with Vickers V2020 pumps, supporting easy retrofit with our full range of vane pumps applications.
