Product Selection Guide
For real-world selection insights, see our V20201F10S10S11AA30L – FluiDyne V2020 case study in automated test stand upgrades.
These five FluiDyne V2020 double vane pump models differ primarily in their total flow rates, individual front/rear pump outputs, rotation direction, port orientations, and maximum operating speeds. All are direct Vickers replacements, share SAE ‘A’ mounting, and are rated up to 2500 PSI, but each model is best suited for distinct hydraulic circuit 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 |
|---|---|---|---|---|
| WF825166 (Current) | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825168 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825165 | 13 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825161 | 13 | 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: Models offer total flows from 10.0 GPM (WF825975) to 22.0 GPM (WF825161), with intermediate options at 12.0, 14.0, and 19.0 GPM.
Selection Guide: Select higher flow models for systems needing greater overall hydraulic output (e.g., WF825161 for 22.0 GPM), or lower flow for precise, smaller systems (WF825975 for 10.0 GPM).
Front/Rear Pump Output
Difference: Front pumps range from 10 to 13 GPM; rear pumps from 0 to 9 GPM. Some models (e.g., WF825975) have near-zero rear pump flow, while others (WF825168, WF825161) provide substantial rear outputs (8–9 GPM).
Selection Guide: Choose models with a high rear pump GPM for dual circuit or Hi-Lo applications, maximizing flexibility (e.g., WF825168 or WF825161). For single circuit or minimal secondary flow, lower rear pump GPM is sufficient.
Rotation Direction
Difference: WF825166, WF825168, and WF825165 are right-hand (clockwise); WF825161 and WF825975 are left-hand (counter-clockwise).
Selection Guide: Match rotation to your existing drive requirements—incorrect rotation will not function in your system.
Maximum Speed
Difference: WF825168 and WF825161 allow speeds up to 2500–2400 RPM; WF825166, WF825165, and WF825975 are limited to 1800 RPM due to rear pump constraints.
Selection Guide: Choose higher speed-capable models for systems operating above 1800 RPM. Models limited to 1800 RPM are ideal for standard low-to-medium speed drives.
Port Orientation
Difference: Port orientations vary—WF825166: front 90° CCW, rear inline; WF825168: both inline; WF825165: both 90° CW; WF825161: both 90° CCW; WF825975: both opposite inlet (180°).
Selection Guide: Select port orientation that matches your system plumbing for easiest installation and minimal line stress.
Shaft Type
Difference: WF825166, WF825168, WF825165, WF825975: 13-tooth splined shaft; WF825161: straight keyed shaft (long extension).
Selection Guide: Splined shafts are preferable for high-torque drives or where coupling misalignment is a concern; straight keyed shafts are standard for most applications.
Quick Selection Guide
If you need: Highest total flow and dual output for priority circuits
Choose: WF825161
Because: It offers the highest total flow (22.0 GPM), dual outputs (13/9 GPM), priority valve cover, and 2400 RPM operation.
If you need: Balanced dual flows with moderate total output
Choose: WF825168
Because: Provides substantial front (11 GPM) and rear (8 GPM) flows, supports up to 19.0 GPM total, and operates at 2500 RPM.
If you need: Maximum front pump flow with minimal secondary output
Choose: WF825165
Because: Delivers 13 GPM front and 1 GPM rear, for applications prioritizing primary circuit flow.
If you need: Standard dual output with basic rear flow
Choose: WF825166
Because: Offers 11 GPM front and 1 GPM rear, suitable for classic Hi-Lo circuits at up to 12 GPM total.
If you need: Lowest flow or single-section operation
Choose: WF825975
Because: Provides 10 GPM total with negligible rear output, ideal for compact or low-flow systems.
