Product Selection Guide
The WF8251xx series of FluiDyne V2020 double vane pumps are part of our extensive hydraulic pumps offering and are all direct Vickers replacements, featuring 100% interchangeability and SAE mounting. Key differences between models are based on the flow rates of the front and rear pumps, total displacement, maximum speed, port orientation, and shaft type. For a broader overview of vane pumps, see our technical category. These differences impact suitability for various hydraulic system requirements—particularly where specific flow, speed, or mounting configurations are critical. For applications requiring single stage vane pumps, see our dedicated range for more options.
?? 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 |
|---|---|---|---|---|
| WF825124 (Current) | 8 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825125 | 13 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825127 | 6 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825121 | 7 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825129 | 9 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Front & Rear Pump Flow Rates
Difference: Front pumps range from 6 to 13 GPM, rear pumps from 6 to 8 GPM.
Selection Guide: Choose higher front pump GPM (e.g., WF825125 at 13 GPM) for applications needing greater primary flow; select models with matched flows (e.g., WF825127 at 6+6 GPM) for balanced circuits.
Total Flow & Displacement
Difference: Total flow ranges from 12.0 GPM (WF825127) up to 20.0 GPM (WF825125); displacement from 2.38 to 4.00 cu.in./rev.
Selection Guide: Use higher total flow/displacement models for larger actuators or faster cycle times; lower flows for precise or lower-volume needs.
Maximum Speed
Difference: Maximum speeds vary: up to 3400 RPM (WF825127), with others limited to 2400–3000 RPM.
Selection Guide: Select WF825127 for high-speed drive systems; others for standard-speed hydraulic power units.
Port Orientation
Difference: WF825124 has outlets opposite the inlet (180°); WF825125, WF825127, WF825129 have outlets inline (0°); WF825121 has outlets at 90° to the inlet.
Selection Guide: Choose port orientation to best match your plumbing layout—inline for straight-through circuits, 180° for opposite line runs, 90° for corner or compact installations.
Shaft Type
Difference: WF825124, WF825125, WF825121 use straight keyed shafts; WF825127 and WF825129 use 13-tooth splined shafts.
Selection Guide: Use splined shafts (WF825127, WF825129) for higher-torque or non-keyed coupling applications.
Mounting Flange
Difference: WF825129 uses an SAE ‘A’ 2-bolt flange; WF825124, WF825125, WF825127, WF825121 use SAE ‘B’ 4-bolt flanges.
Selection Guide: Check your system’s mounting style—select SAE ‘A’ (WF825129) for smaller frames, SAE ‘B’ for standard V2020 replacements.
Quick Selection Guide
If you need: Balanced dual flows at high RPM
Choose: WF825127
Because: Offers 6+6 GPM at up to 3400 RPM with splined shaft—ideal for compact, high-speed circuits requiring equal flows.
If you need: Maximum total flow
Choose: WF825125
Because: Provides 20 GPM (13+7 GPM) for systems demanding high volume, with standard keyed shaft and inline porting.
If you need: Standard mid-range flow with opposite porting
Choose: WF825124
Because: Delivers 8+8 GPM, 16 GPM total, with outlets opposite the inlet—suitable for layouts requiring 180° port orientation.
If you need: Compact mounting with splined shaft
Choose: WF825129
Because: Features 9+7 GPM flow, SAE ‘A’ 2-bolt flange, and splined shaft—best for space-limited, high-torque drives.
If you need: Balanced moderate flow with 90° ports
Choose: WF825121
Because: Offers 7+7 GPM, with 90° port orientation—suits right-angle plumbing in confined installations.
Compatibility: All models are direct Vickers replacements applications, 100% interchangeable, and meet SAE J744 mounting with G1″/G1/2″ BSPP ports for straightforward retrofit or upgrade.
