Product Selection Guide
These FluiDyne vane pumps all offer direct Vickers interchangeability and share common mounting, port, and pressure specs, but differ in total flow, pump section sizing, rotation, shaft type, port orientation, and maximum speed. Selection depends primarily on the required total flow, dual-output needs, rotational direction, and installation constraints.
?? 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 |
|---|---|---|---|---|
| WF825940 (Current) | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825942 | 8 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825948 | 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 Output
Difference: WF825940 delivers 16.0 GPM (11 + 5 GPM); WF825942 offers 15.0 GPM (8 + 7 GPM); WF825948 provides the highest at 17.0 GPM (8 + 9 GPM); WF825975 and WF825063 both output 10.0 GPM (single active section).
Selection Guide: Choose WF825948 for the highest combined flow (17.0 GPM), or WF825940/WF825942 for balanced dual outputs. Select WF825975 or WF825063 if your system only needs a single effective flow section.
Pump Section Sizing
Difference: WF825940: Front 11 GPM, Rear 5 GPM; WF825942: Front 8 GPM, Rear 7 GPM; WF825948: Front 8 GPM, Rear 9 GPM; WF825975/WF825063: Front 10 GPM, Rear 0 GPM.
Selection Guide: Select pumps with a larger rear section (WF825948) for applications needing more flow for a secondary circuit—this is common in FluiDyne V20 Pump configurations for mobile and industrial machinery. Choose more balanced pumps (WF825942) for systems where dual outputs need to be similar.
Maximum Speed (RPM)
Difference: WF825942/WF825948: Up to 2800 RPM; WF825940/WF825975/WF825063: Limited to 1800 RPM (due to rear section).
Selection Guide: If your application requires higher-speed operation, select WF825942 or WF825948.
Shaft Type
Difference: WF825940 uses a straight keyed shaft; WF825942, WF825948, WF825975, WF825063 use 13-tooth splined shafts.
Selection Guide: Choose straight keyed shaft (WF825940) for standard couplings; pick splined shaft models for higher-torque applications or when using splined drive couplings, as seen in V201P5P18C11R – FluiDyne V20 Pump builds.
Rotation Direction
Difference: WF825940, WF825942, WF825948, WF825063: Right-hand (clockwise); WF825975: Left-hand (counter-clockwise).
Selection Guide: Always match pump rotation to your drive system. Use WF825975 if a left-hand (counter-clockwise) pump is required.
Port Orientation
Difference: WF825940, WF825942, WF825975, WF825063: Both outlets opposite inlet (180°); WF825948: Outlets inline with inlet (0°).
Selection Guide: Select 180° orientation for standard layouts; use 0° (WF825948) for streamlined, inline hydraulic connections such as those found in V20201F10S10S11AA30L – FluiDyne V2020 applications.
Quick Selection Guide
If you need: Highest total flow output (17.0 GPM) and inline porting
Choose: WF825948
Because: It offers the greatest combined flow and streamlined installation with inline ports.
If you need: Balanced dual outputs with higher maximum RPM (up to 2800)
Choose: WF825942
Because: Front and rear sections are closely matched (8 and 7 GPM), suitable for Hi-Lo circuits with similar demands and higher speed drives.
If you need: A larger primary flow with a secondary low-flow section (total 16.0 GPM)
Choose: WF825940
Because: The 11 GPM front and 5 GPM rear sections are optimal for primary/secondary circuits where main and auxiliary flows differ.
If you need: Single output at 10 GPM with right or left-hand rotation
Choose: WF825063 (right-hand) or WF825975 (left-hand)
Because: These models provide a single active section, ideal for simpler systems or replacements requiring a specific rotation, especially in systems utilizing pumps with integral valves.
Compatibility: All models feature SAE ‘B’ 4-bolt flange mounting and 1-1/16″-12 UN-2B thread ports, ensuring 100% direct interchangeability with Vickers replacement pumps. Pressure ratings are up to 2500 PSI across all models.
