Product Selection Guide
These FluiDyne V2020 double vane pumps are all direct Vickers replacements, sharing core specs like max pressure (2500 PSI), displacement (1.19 in³/rev) — see full hydraulic pumps family for broader selection., and port sizes. Key differences are in total flow rate, pump speed limitations, shaft type/rotation, port orientation, and mounting flanges. For alternative single stage vane pumps, browse our dedicated section. These distinctions determine suitability for various hydraulic system layouts, flow demands, and drive arrangements.
?? 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.

Key Differences
Total Flow Rate
Difference: WF8251089 and WF8251074 deliver 18.0 GPM; WF8251091 offers 17.0 GPM; WF8251014 and WF8251052 provide a lower total flow at 14.0 GPM.
Selection Guide: Use WF8251089 or for applications demanding higher combined flow; and fit systems where lower flow is sufficient.
Rear Pump Flow and Speed
Difference: WF8251089 and have 7 GPM rear pumps (max 3000 RPM); ‘s rear pump is 6 GPM (max 3400 RPM); and have 2 GPM rear pumps (max 1800 RPM).
Selection Guide: Choose if you need a slightly faster rear section; select WF8251089 or for more balanced high flow front and rear; opt for or for applications with minimal rear flow.
Maximum Speed (RPM)
Difference: WF8251089, , and max out at 2500 RPM; and are limited to 1800 RPM by their rear pump.
Selection Guide: Pick WF8251089, , or for applications with higher drive speeds; use or where lower speeds are acceptable or preferred.
Mounting Flange
Difference: WF8251089 uses SAE ‘A’ 2-bolt; others use SAE ‘B’ 4-bolt.
Selection Guide: Choose based on your system’s flange compatibility—WF8251089 for SAE ‘A’, others for SAE ‘B’.
Port Orientation
Difference: WF8251089 and have both outlets opposite the inlet (180°); and have both outlets inline with inlet (0°); has the front outlet at 90° CCW and rear opposite (180°).
Selection Guide: Select the port orientation that aligns with your plumbing—’inline’ for straight-through connections, ‘opposite’ for back-to-back, ’90°’ for tight or side-entry spaces.
Shaft Type and Rotation
Difference: uses a 13-tooth splined shaft and is left-hand (CCW); all others have a straight keyed shaft (most right-hand, except , which is left-hand).
Selection Guide: Pick splined shaft () for higher torque or splined couplings; choose rotation to match your drive direction.
Quick Selection Guide
If you need: Highest total flow (18.0 GPM) with right-hand rotation and SAE ‘A’ mounting
Choose: WF8251089
Because: It offers the highest combined flow with a common keyed shaft and standard port orientation—ideal for systems using SAE ‘A’ 2-bolt flanges.
If you need: High flow (18.0 GPM) with left-hand rotation and splined shaft
Choose:
Because: It supports applications requiring CCW drive and splined coupling, with inline port orientation for direct plumbing.
If you need: A compact double pump with slightly reduced rear flow (6 GPM) and 90° outlet
Choose:
Because: Its 90° front port is helpful in tight layouts; higher rear pump speed can suit fast auxiliary circuits.
If you need: Lower total flow (14.0 GPM) with minimal rear pump demand
Choose: (left-hand) or (right-hand)
Because: Both are suitable for systems where the rear section is for pilot or low-flow circuits; choose rotation and port orientation to match your setup.
Compatibility: All models are 100% interchangeable with Vickers equivalents and meet SAE J744 standards. For a full list of Vickers replacement pumps, see our compatibility section. Port sizes and displacement are consistent across the range, simplifying system integration and replacement.
