Product Selection Guide
These FluiDyne V2020 double vane pump models differ primarily in total flow output, rear pump contribution, shaft type, rotation direction, port orientation, and maximum speed. For broader selection, see our hydraulic pumps lineup. All are direct Vickers replacements, share SAE ‘B’ 4-bolt flange mounting, and support up to 2500 PSI, but each is tailored for particular 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 |
|---|---|---|---|---|
| WF825538 (Current) | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825539 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825533 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825535 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| V20201F10S10S11AA30L – FluiDyne V2020 (19.5 cm³/r (1.19 in³/r)) | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Total Flow Output
Difference: WF825538 delivers the highest total flow at 19.0 GPM (11 GPM front + 8 GPM rear). WF825975 provides the lowest at 10.0 GPM (front only). The other models (WF825539, WF825533, WF825535) are at 12.0 GPM (front + minimal rear flow).
Selection Guide: Choose WF825538 when you need higher combined flow for systems with greater simultaneous actuator demand. Select WF825975 for compact applications needing only single-section flow.
Rear Pump Output
Difference: WF825538 offers 8 GPM from the rear section, while WF825539, WF825533, and WF825535 have minimal rear output (1 GPM), and WF825975 has 0 GPM.
Selection Guide: If your system requires two separate flows (e.g., Hi-Lo circuits), models with rear output (especially WF825538) are preferable. For advanced applications, consider pumps with integral valves.
Maximum Speed
Difference: WF825538 supports up to 2500 RPM (limited by front pump), whereas all other models are limited to 1800 RPM due to their rear pump sections.
Selection Guide: Select WF825538 for higher-speed applications, or when matching to a faster motor.
Shaft Type
Difference: WF825539 and WF825975 use a 13-tooth splined shaft; others use a straight keyed shaft.
Selection Guide: Splined shafts (WF825539, WF825975) are recommended for high-torque or vibration-prone environments; straight keyed shafts are suitable for standard couplings. For single-section needs, browse our single stage vane pumps.
Rotation Direction
Difference: WF825539 is right-hand (clockwise), while the other models are left-hand (counter-clockwise) rotation.
Selection Guide: Ensure you match the pump rotation to your prime mover’s direction—choose WF825539 if you need clockwise.
Port Orientation
Difference: WF825538 and WF825975 have both outlets opposite the inlet (180°); WF825533 has both outlets inline with the inlet (0°); WF825539 and WF825535 have mixed orientations (front 90° CCW or rear 90° CCW).
Selection Guide: Select port orientation based on your piping layout—for straight-through access, choose 180°; for alignment with existing lines, inline (0°) or 90° options may reduce installation complexity.
Design Series
Difference: All models are Design Series 30 except WF825975, which is not explicitly stated but likely similar.
Selection Guide: Use Design Series 30 for consistency with current maintenance parts.
Quick Selection Guide
If you need: Highest combined flow (19.0 GPM) and fastest operation (up to 2500 RPM)
Choose: WF825538
Because: It offers significant front and rear pump output and supports higher speed for demanding systems.
If you need: Minimal rear flow with right-hand (clockwise) rotation and splined shaft
Choose: WF825539
Because: This model suits systems requiring clockwise drive and enhanced torque transfer.
If you need: Minimal rear flow, left-hand (counter-clockwise) rotation, and both outlets inline with inlet
Choose: WF825533
Because: It simplifies installation where straight-through porting is ideal. For more information on similar applications, see V201P13P3C11R – FluiDyne V20 Pump (42.6 cm³/r (2.60 in³/r)).
If you need: Flow control cover for additional circuit management and rear tank/pressure ports
Choose: WF825535
Because: Ideal for applications needing integrated flow control and unique porting.
If you need: Lowest flow (10.0 GPM) with left-hand rotation and splined shaft
Choose: WF825975
Because: Designed for compact, single-section applications requiring robust shaft connection.
Compatibility: All models are direct Vickers replacements and use SAE ‘B’ 4-bolt flange mounting with G1″ and G1/2″ BSPP straight thread ports for straightforward interchangeability.
