Product Selection Guide
These FluiDyne V2020 double vane pumps differ primarily in total flow output, front/rear pump flow balance, port orientation, shaft type, rotation direction, and speed limits. All are direct Vickers replacements with SAE ‘A’ mounting and G1″/G1/2″ BSPP ports, making them fully interchangeable for most applications.
?? 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 specifications applications before ordering or review our vane pump technical resources to ensure compatibility with your application. We cannot accept returns due to specification mismatches.
| Model Number | Flow Rate | Max Pressure | Displacement | Mounting |
|---|---|---|---|---|
| WF825116 (Current) | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8251121 | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825111 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825115 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |

Key Differences
Total Flow Rate
Difference: WF8251115 delivers the highest total flow at 20.0 GPM; WF825116 is next at 19.0 GPM; WF8251121 offers 15.0 GPM; WF825111 and WF825115 provide 12.0 GPM each.
Selection Guide: Select WF8251115 or WF825116 when higher system flow is needed, such as for larger actuators or faster cycle times. Choose WF8251121, WF825111, or WF825115 if your application requires lower combined flows or tighter flow control.
Front/Rear Pump Flow Split
Difference: WF825116 and WF8251115 offer balanced high flows on both sections (11+8 and 12+8 GPM); WF8251121, WF825111, and WF825115 have a larger difference between front and rear (e.g., 11+1 GPM).
Selection Guide: Use balanced models (WF825116, WF8251115) for circuits needing similar flow rates to two functions; choose unbalanced models for Hi-Lo circuits or where a small secondary flow is needed.
Maximum Speed
Difference: WF8251115 allows up to 2400 RPM; WF825116 up to 2500 RPM; others are limited by the rear pump to 1800 RPM (WF8251121, WF825111, WF825115).
Selection Guide: Choose WF825116 or WF8251115 for high-speed drives or where pump speed flexibility is required.
Rotation Direction
Difference: WF825116 and WF825115 are right-hand (clockwise); WF8251121, WF825111, and WF8251115 are left-hand (counter-clockwise).
Selection Guide: Select according to your drive rotation—ensure the pump matches your motor/engine direction.
Port Orientation
Difference: WF825116: both outlets 90° CCW from inlet; WF825115: both outlets 90° CW from inlet; WF8251121: front outlet opposite, rear inline; WF825111 and WF8251115: both outlets opposite inlet.
Selection Guide: Match port orientation to your piping layout for easiest installation.
Shaft Type
Difference: WF825116, WF8251121, WF8251115: straight keyed shaft; WF825111 and WF825115: 13-tooth splined shaft.
Selection Guide: Choose splined shafts (WF825111, WF825115) for high-torque or splined coupler setups; use straight keyed shafts for standard couplings.
Quick Selection Guide
If you need: Highest total flow and balanced output to two circuits
Choose: WF8251115 (20.0 GPM, 12+8 GPM, 2400 RPM, left-hand) or WF825116 (19.0 GPM, 11+8 GPM, 2500 RPM, right-hand)
Because: These models maximize available flow for demanding machinery and support flexible mounting.
If you need: A moderate total flow with greater front pump output
Choose: WF8251121 (15.0 GPM, 10+5 GPM, left-hand)
Because: Best for applications with one main circuit and a smaller secondary function.
If you need: Very low secondary flow (e.g., pilot or lube circuit)
Choose: WF825111 or WF825115 (12.0 GPM, 11+1 GPM, 1800 RPM, splined shaft)
Because: Ideal for Hi-Lo circuits or applications needing minimal flow to a second function.
If you need: Right-hand rotation and high speed
Choose: WF825116 or WF825115
Because: Both support clockwise drive, with WF825116 offering the highest speed.
If you need: Left-hand rotation and high flow
Choose: WF8251115
Because: Provides 20.0 GPM at 2400 RPM with CCW rotation.
Compatibility: All models are 100% interchangeable with Vickers V2020 series, use SAE ‘A’ 2-bolt mounting, and G1″ / G1/2″ BSPP straight thread ports. They meet SAE J744 standards for easy swap-in replacement.
