Product Selection Guide
For a broader selection, view all hydraulic pumps and vane pump options at Northern Hydraulics.
The five FluiDyne V2020 double vane pumps compared here differ mainly in total flow output, port orientation, shaft type, rotation direction, and the specific GPM delivered by the front and rear pump sections. While all models maintain the same pressure rating, mounting, and high Vickers interchangeability, subtle variations make each best suited for different hydraulic system requirements.
?? 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 |
|---|---|---|---|---|
| WF825541 (Current) | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825540 (vane pump family) | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825544 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825975 (Vickers replacement) | 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 (GPM)
Difference: WF825540 and WF825544 deliver higher total flow (19.0 GPM) with dual pump sections (11 GPM front + 8 GPM rear), while WF825541, WF825975, and WF825063 offer lower output (12.0 or 10.0 GPM) with little or no rear pump flow.
Selection Guide: Select WF825540 or WF825544 for systems needing more simultaneous flow or dual-circuit operation; choose WF825541, WF825975, or WF825063 for single-circuit or lower-demand applications.
Rear Pump Flow
Difference: WF825540 and WF825544 provide 8 GPM from the rear section; WF825541 offers only 1 GPM, and WF825975/WF825063 offer 0 GPM rear flow.
Selection Guide: For two distinct flows (such as Hi-Lo circuits), use WF825540 or WF825544; for primarily single-flow needs, WF825975 or WF825063 are more suitable.
Maximum Speed (RPM)
Difference: WF825540 and WF825544 support up to 2500 RPM (limited by front pump); WF825541, WF825975, and WF825063 are limited to 1800 RPM due to rear pump constraints.
Selection Guide: Choose WF825540 or WF825544 for higher-speed systems or where maximizing flow at RPM is important.
Port Orientation
Difference: WF825540: Front inline, rear 90° CCW; WF825544: Both outlets inline; WF825541: Front opposite (180°), rear inline; WF825975/WF825063: Both outlets opposite (180°).
Selection Guide: Select port orientation that matches your piping layout—inline for straight-through connections, 90° or opposite for more complex or space-restricted installations.
Shaft & Rotation
Difference: WF825540, WF825541, and WF825975 use a 13-tooth splined shaft, left-hand rotation; WF825544 and WF825063 use a straight keyed shaft, right-hand rotation.
Selection Guide: Match shaft and rotation to your drive coupling and motor direction—splined shafts for higher torque, keyed for standard; left-hand vs right-hand rotation must match your system.
Quick Selection Guide
If you need: Dual-circuit operation or highest total flow (19.0 GPM)
Choose: WF825540 (front inline/rear 90° CCW, left-hand, splined) or WF825544 (both inline, right-hand, straight keyed)
Because: These models offer both 11 GPM and 8 GPM sections, ideal for independent flows.
If you need: A small auxiliary circuit or minimal rear flow (1 GPM)
Choose: WF825541
Because: This model provides a main 11 GPM flow with a small 1 GPM secondary flow, suitable for light pilot or auxiliary functions.
If you need: Single-circuit operation with moderate flow (10 GPM) and no rear flow
Choose: WF825975 (left-hand, splined, both outlets opposite) or WF825063 (right-hand, straight keyed, both outlets opposite)
Because: These models focus all output to the front section, best for systems without a secondary circuit.
If you need: Specific port orientation or rotation for a retrofit
Choose: Match WF825544 or WF825063 for right-hand rotation and inline/opposite ports; WF825540, WF825541, or WF825975 for left-hand rotation or special port angles.
Because: Proper alignment reduces installation time and avoids piping modifications.
Compatibility: All models are direct Vickers replacements, 100% interchangeable, and feature SAE ‘A’ size 2-bolt flanges with G1″/G1/2″ BSPP straight thread ports for seamless integration. They meet SAE J744 standards and support up to 2500 PSI.
