Product Selection Guide
These FluiDyne V2020 double vane pumps are all direct Vickers replacements, sharing core specs. For additional V2020 models, see V20201F10S10S11AA30L – FluiDyne V2020 for similar displacement and mounting. like 2500 PSI max pressure, SAE ‘A’ 2-bolt mounting, and G1″/G1/2″ BSPP ports. Key differences lie in total flow rates, rear pump sizes, rotation direction, port orientation, and shaft type—factors that determine suitability for various hydraulic system layouts and required flow combinations.
?? 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 |

Key Differences
Total Flow Rate
Difference: WF8251075 delivers the highest total flow at 21.0 GPM (front: 12 GPM, rear: 9 GPM); WF8251091 outputs 17.0 GPM (front: 11 GPM, rear: 6 GPM); WF8251074 offers 18.0 GPM (front: 11 GPM, rear: 7 GPM); WF8251014 and WF8251052 each provide 14.0 GPM (front: 12 GPM, rear: 2 GPM).
Selection Guide: Choose WF8251075 for high-flow dual-circuit requirements; opt for WF8251014 or WF8251052 when a small secondary flow is needed. For other high-displacement models, consider the V201P5P18C11R – FluiDyne V20 Pump.
Rear Pump Size
Difference: Rear pump on WF8251075 is 9 GPM; WF8251091 is 6 GPM; WF8251074 is 7 GPM; WF8251014 and WF8251052 are 2 GPM.
Selection Guide: Select models with larger rear pump (WF8251075, WF8251074, WF8251091) for applications needing significant secondary flow. For minimal secondary requirements, WF8251014 or WF8251052 suffice.
Rotation Direction
Difference: WF8251075, WF8251091, and WF8251052 are right-hand (clockwise); WF8251074 and WF8251014 are left-hand (counter-clockwise).
Selection Guide: Match pump rotation to your drive system—use right-hand for standard engine drives, left-hand for reverse or special applications.
Port Orientation
Difference: WF8251075 and WF8251014: both outlets opposite inlet (180°); WF8251091: front outlet 90° CCW, rear 180°; WF8251074 and WF8251052: both outlets inline with inlet (0°).
Selection Guide: Choose 180° for installations with rearward plumbing; 0° (inline) for side-by-side connections; 90° for corner or tight-fit scenarios.
Shaft Type
Difference: WF8251074 uses a 13-tooth splined shaft (good for high-torque needs); other models have straight keyed shafts.
Selection Guide: Select splined shaft for higher torque or when using splined couplings; straight keyed for standard setups.
Maximum Speed (RPM)
Difference: WF8251075: 2400 RPM; WF8251091 and WF8251074: 2500 RPM; WF8251014 and WF8251052: 1800 RPM (limited by rear pump).
Selection Guide: Use higher RPM models for faster cycling systems or where drive speed is critical; lower RPM models for slower, high-torque operations.
Model Number Patterns
Difference: WF82510XX: The last two digits reflect front/rear pump size combinations and features. ’75’ (WF8251075) has the largest rear pump (9 GPM), ’91’ and ’74’ mid-range, ’14’ and ’52’ the smallest (2 GPM).
Selection Guide: Select model numbers ending in ’75’ for max rear flow, ’14’ or ’52’ for minimal rear flow.
Quick Selection Guide
If you need: Maximum combined flow and substantial dual-circuit capability
Choose: WF8251075 (21.0 GPM, 12+9 GPM, 2400 RPM, right-hand, 180° ports)
Because: Best for systems needing high flows on both circuits, such as industrial presses with separate high/low functions.
If you need: Moderate dual flow with flexible port orientation
Choose: WF8251074 (18.0 GPM, 11+7 GPM, 2500 RPM, left-hand, inline ports)
Because: Suited for mid-size machines requiring two moderate flows and a splined shaft for high-torque connections. For higher displacement in similar applications, see V201P13P3A11R – FluiDyne V20 Pump.
If you need: Compact dual flow with higher RPM drive
Choose: WF8251091 (17.0 GPM, 11+6 GPM, 2500 RPM, right-hand, 90°/180° ports)
Because: Ideal for applications with limited rear flow requirements and unique porting needs.
If you need: Major flow on one circuit, minimal on the second
Choose: WF8251014 (14.0 GPM, 12+2 GPM, 1800 RPM, left-hand, 180° ports) or WF8251052 (14.0 GPM, 12+2 GPM, 1800 RPM, right-hand, inline ports)
Because: Best for scenarios where a primary circuit needs the majority of flow, with a small secondary requirement.
