Common Applications
Commonly used in marine applications, stationary power units, test stands. For similar real-world installations, see our V20 pump case studies.
- marine applications
- stationary power units
- test stands
Important: Verify pump model WF825747 matches your existing Vickers unit before ordering. For technical assistance, contact (800) 823-4937.
Product Selection Guide
These Fluidyne V2020 double vane pumps are direct Vickers replacements, sharing the same SAE mountings, pressure ratings, and port sizes, but vary primarily in total flow rate, shaft type, rotation, and port orientation. Selection should be based on your system’s required total flow, preferred shaft coupling, rotation, and space/layout constraints. For a broader overview of available technologies, view our pumps with integral valves.
?? 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 |
|---|---|---|---|---|
| WF825747 (Current) | 12 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825741 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825748 | 13 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825740 | 9 | 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) |
Key Differences
Total Flow Rate
Difference: WF825748 provides the highest total flow at 19.0 GPM, followed by WF825741 at 18.0 GPM, WF825747 at 13.0 GPM, WF825740 at 10.0 GPM, and WF825975 at 10.0 GPM.
Selection Guide: Choose WF825748 or WF825741 for applications needing higher combined system flow, such as larger actuators or multi-function circuits. Select WF825747, WF825740, or WF825975 for lower flow needs or when precise flow division is more important.
Front and Rear Pump Flows
Difference: Models split total flow differently: WF825747 (Front 12 GPM / Rear 1 GPM), WF825741 (Front 11 GPM / Rear 7 GPM), WF825748 (Front 13 GPM / Rear 6 GPM), WF825740 (Front 9 GPM / Rear 1 GPM), WF825975 (Front 10 GPM / Rear 0 GPM).
Selection Guide: Pick based on your required flow split for Hi-Lo circuits: WF825741 and WF825748 offer more balanced front/rear flows for dual circuit operation, while others favor a dominant front section.
Shaft Type and Size
Difference: WF825741 and WF825975 feature a 13-tooth splined shaft; others use a straight keyed shaft.
Selection Guide: Select splined shafts (WF825741, WF825975) for higher torque or more robust coupling. Use straight keyed shafts (WF825747, WF825748, WF825740) for standard applications.
Rotation Direction
Difference: WF825747, WF825740, and WF825975 are left-hand (counter-clockwise); WF825741 and WF825748 are right-hand (clockwise).
Selection Guide: Match rotation to your existing drive system: left-hand for counter-clockwise rotation, right-hand for clockwise.
Port Orientation
Difference: WF825747, WF825740, and WF825975 have outlet ports opposite the inlet (180°); WF825741 and WF825748 have outlets inline with the inlet (0°).
Selection Guide: Choose 180° for installations needing outlets on the opposite side of the inlet, 0° for same-side plumbing.
Special Cover Option
Difference: WF825740 is the only model with a priority valve cover, providing primary and secondary flows plus a tank port.
Selection Guide: Use WF825740 if your application requires priority flow division for steering or safety circuits. You can also explore pumps with integral valves for integrated control.
Maximum Speed
Difference: WF825748 offers the highest max speed (2400 RPM), WF825741 up to 2500 RPM, others are capped at 1800 RPM.
Selection Guide: For higher speed drives, choose WF825748 or WF825741. To compare technical specs, review our V201P13P3A11R V20 Pump for similar applications. For standard 1800 RPM motors, any model is suitable.
Quick Selection Guide
If you need: Highest total system flow (19.0 GPM) and higher speed (2400 RPM)
Choose: WF825748
Because: It supports the greatest combined flow and a higher RPM, ideal for demanding circuits.
If you need: Balanced dual circuit flows (11 GPM front / 7 GPM rear) and right-hand rotation
Choose: WF825741
Because: It offers two substantial flows for simultaneous or Hi-Lo circuit use, and a splined shaft for higher torque.
If you need: Low total flow but require a priority valve cover (for steering or safety circuits)
Choose: WF825740
Because: It uniquely includes a priority valve cover for dividing primary/secondary flows.
If you need: Smaller, single-section flow (10 GPM front only), left-hand rotation, and splined shaft
Choose: WF825975
Because: Ideal for single circuit use with robust shaft coupling.
If you need: Compact flow split (12 GPM front / 1 GPM rear), left-hand rotation, and opposite port orientation
Choose: WF825747
Because: Best for applications needing a dominant main flow with a minor secondary circuit.
Compatibility: All models use SAE ‘A’ 2-bolt mounting, G1″ and G1/2″ BSPP straight thread ports, and are fully interchangeable with Vickers V2020 double vane pumps. For a full range of compatible options, visit our Vickers replacement pumps page.
