Product Selection Guide
These FluiDyne V2020 double vane pumps are all direct Vickers replacements, ideal for hydraulic systems needing dual flows in a compact footprint. The primary differences among models are in total flow rates, individual front/rear pump outputs, maximum allowable speeds, port orientation, rotation direction, and shaft type. Choosing the right model ensures optimal performance for specific circuit requirements and installation layouts.
?? 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 |
|---|---|---|---|---|
| WF825253 (Current) | 13 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825258 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825257 | 12 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825252 | 6 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825251 | 9 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Total Flow Rate
Difference: Models offer total flows from 12.0 to 20.0 GPM. WF825258 provides the highest at 20.0 GPM (11 GPM front + 9 GPM rear), while WF825252 is lowest at 12.0 GPM (6 GPM front + 6 GPM rear).
Selection Guide: Select higher flow models (WF825258, WF825257, WF825251) for larger actuators or higher system demand. Choose WF825252 for smaller systems or where lower flows are sufficient.
Individual Pump Flow
Difference: Front/rear pump combinations vary: WF825253 is 13/1 GPM, WF825258 is 11/9 GPM, WF825257 is 12/6 GPM, WF825252 is 6/6 GPM, WF825251 is 9/9 GPM.
Selection Guide: Pick a model with a higher front or rear pump flow depending on which circuit requires more volume. For example, WF825253 suits applications needing a high primary flow and low secondary flow.
Maximum Speed (RPM)
Difference: WF825252 supports the highest RPM at 3400; WF825253 is limited to 1800 RPM (by rear pump). Others range from 2400 to 2800 RPM.
Selection Guide: Select WF825252 if your application requires higher speed operation or variable speed drives.
Port Orientation
Difference: WF825253 and WF825251 have outlets opposite the inlet (180°); WF825258 and WF825252 have outlets inline with inlet (0°); WF825257 has front/rear outlets at 90°.
Selection Guide: Match port orientation to your plumbing layout: choose 180° for opposite connections, 0° for inline, and 90° for side exits in tight installations.
Rotation Direction
Difference: WF825253, WF825252, and WF825251 are left-hand (CCW); WF825258 and WF825257 are right-hand (CW).
Selection Guide: Match rotation to your drive motor direction. Incorrect rotation can damage the pump.
Shaft Type
Difference: WF825253 and WF825258 use straight keyed shafts; WF825257, WF825252, and WF825251 use 13-tooth splined shafts.
Selection Guide: Choose splined shafts for higher torque or when using splined couplings. Use straight keyed for standard keyed connections.
Quick Selection Guide
If you need: Maximum total flow (20.0 GPM) and balanced dual outputs
Choose: WF825258
Because: It provides 11 GPM front and 9 GPM rear, ideal for high-demand dual-circuit systems.
If you need: High primary flow with minimal secondary flow
Choose: WF825253
Because: It delivers 13 GPM front and 1 GPM rear—suited for Hi-Lo circuits where a brief high flow is required.
If you need: Equal flow to two circuits with high speed capability
Choose: WF825252
Because: Both pumps deliver 6 GPM and support up to 3400 RPM—good for balanced, high-speed applications.
If you need: Medium, balanced flow with splined shaft and left-hand rotation
Choose: WF825251
Because: It offers 9 GPM from both sections, left-hand rotation, and a splined shaft for robust coupling.
If you need: Medium total flow with different front/rear outputs and right-hand rotation
Choose: WF825257
Because: It gives 12 GPM front, 6 GPM rear, 90° port orientation, and a splined shaft.
Compatibility: All models are 100% interchangeable with Vickers equivalents, use SAE ‘B’ 4-bolt flange mounting, meet SAE J744 standards, and feature standardized G1″/G1/2″ BSPP or 1-1/16″-12 UN-2B threaded ports for straightforward replacement.
