Important: Verify pump model WF8251040 matches your existing Vickers unit before ordering. For technical assistance, contact (800) 823-4937.
Product Selection Guide
These FluiDyne V2020 double vane pump models are all direct Vickers replacements, but differ in total flow rate, rear pump size, port orientation, shaft style, rotation direction, and maximum speed. Selection depends on your target system flow, desired port arrangement, shaft type for coupling, and rotation 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 |
|---|---|---|---|---|
| WF8251040 (Current) | 12 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8251091 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8251074 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8251014 | 12 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8251052 | 12 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Total Flow Rate
Difference: WF8251040 delivers 20.0 GPM, WF8251074 delivers 18.0 GPM, WF8251091 delivers 17.0 GPM, and WF8251014/WF8251052 deliver 14.0 GPM. If you require a similar flow in a single-stage design, consider the V201P5P18C11R – FluiDyne V20 Pump.
Selection Guide: Choose WF8251040 for highest system flow, WF8251014 or WF8251052 for lower flow requirements or smaller circuits.
Rear Pump Output
Difference: WF8251040: 8 GPM rear; WF8251074: 7 GPM rear; WF8251091: 6 GPM rear; WF8251014/WF8251052: 2 GPM rear.
Selection Guide: Select higher rear pump GPM (WF8251040, WF8251074) for applications needing substantial secondary flow, such as dual circuit or Hi-Lo systems. For pumps with integrated control options, explore our pumps with integral valves applications.
Maximum Speed
Difference: WF8251040, WF8251074, WF8251091: up to 2400–2500 RPM; WF8251014, WF8251052: 1800 RPM (limited by rear pump).
Selection Guide: Choose models with higher max speed for faster cycle rates or higher drive speeds.
Port Orientation
Difference: WF8251040, WF8251074, WF8251052: both outlets inline with inlet (0°); WF8251091: front 90° CCW, rear opposite (180°); WF8251014: both outlets opposite inlet (180°).
Selection Guide: Inline orientation (0°) simplifies straight plumbing; 90° or 180° may suit compact or custom layouts.
Shaft Type
Difference: WF8251040, WF8251074: 13-tooth splined; WF8251091, WF8251014, WF8251052: straight keyed shaft.
Selection Guide: Splined shafts (WF8251040, WF8251074) are best for high-torque or spline-coupled drives; keyed shafts (others) suit standard couplings.
Rotation Direction
Difference: WF8251040, WF8251074, WF8251014: left-hand (CCW); WF8251052, WF8251091: right-hand (CW).
Selection Guide: Match pump rotation to your drive motor direction.
Quick Selection Guide
If you need: Maximum combined flow and substantial secondary circuit (8 GPM rear)
Choose: WF8251040
Because: Delivers the highest total (20 GPM) and rear pump (8 GPM) output—ideal for dual-flow or Hi-Lo circuits needing strong secondary flow.
If you need: Moderate dual flow with higher primary GPM and left-hand rotation
Choose: WF8251074
Because: Offers 11 + 7 GPM split for balanced dual circuit applications.
If you need: Moderate dual flow with right-hand rotation and unique porting
Choose: WF8251091
Because: Provides 11 + 6 GPM with 90° CCW and 180° port orientation for custom mounting.
If you need: Lower secondary flow (2 GPM rear) and left-hand rotation
Choose: WF8251014
Because: Best for primary circuits that only need minimal secondary flow. For higher capacity single-stage circuits, review the V201P13P3A11R – FluiDyne V20 Pump. Both outlets are opposite the inlet.
If you need: Lower secondary flow (2 GPM rear) and right-hand rotation with inline ports
Choose: WF8251052
Because: Best for compact layouts requiring right-hand rotation and inline porting.
Compatibility: All models are 100% Vickers V2020 interchangeable, use SAE ‘B’ 4-bolt flange mounting, and accommodate G1″/G1/2″ BSPP straight thread ports. This ensures easy integration into existing Vickers systems.
