Product Selection Guide
These FluiDyne V2020 double vane pump models are differentiated primarily by their combined flow rates, individual front/rear pump capacities, shaft type, rotation direction, port orientation, and maximum speed. All models are direct Vickers replacements and adhere to SAE mounting and port standards for full interchangeability. Selection should be based on your system’s required total flow, preferred port orientation, shaft and rotation compatibility, and operating speed limitations.
?? 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 |
|---|---|---|---|---|
| WF8251009 (Current) | 7 | 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: WF8251074 delivers the highest combined flow at 18.0 GPM; WF8251091 offers 17.0 GPM; WF8251014 and WF8251052 provide 14.0 GPM; WF8251009 outputs 13.0 GPM.
Selection Guide: Select WF8251074 or WF8251091 for systems needing higher total flow, such as larger actuators or parallel circuits. Choose WF8251009, WF8251014, or WF8251052 for moderate flow requirements.
Front/Rear Pump Flow Split
Difference: WF8251009 (7 GPM front / 6 GPM rear), WF8251074 & WF8251091 (11 GPM front / 6 or 7 GPM rear), WF8251014 & WF8251052 (12 GPM front / 2 GPM rear).
Selection Guide: If you require a balanced split between two circuits, WF8251009 is suitable. For a high/low flow split (e.g., main/auxiliary functions), WF8251014 or WF8251052 are ideal.
Maximum Speed Limitation
Difference: WF8251009 and WF8251074 allow up to 3000 RPM; WF8251091 is limited to 2500 RPM; WF8251014 and WF8251052 are capped at 1800 RPM.
Selection Guide: Choose WF8251009 or WF8251074 for higher-speed systems. Use WF8251014 or WF8251052 for lower-speed, high-torque applications.
Shaft Type
Difference: WF8251009 and WF8251074 use a 13-tooth splined shaft; WF8251014 and WF8251052 use a straight keyed shaft; WF8251091’s shaft is code 5 (not further specified but likely straight keyed).
Selection Guide: Splined shafts (WF8251009, WF8251074) handle higher torque and are preferred for demanding applications. Choose straight keyed variants (WF8251014, WF8251052, likely WF8251091) if compatible with your couplings.
Rotation Direction
Difference: WF8251009, WF8251074, WF8251014 are left-hand (CCW); WF8251091, WF8251052 are right-hand (CW).
Selection Guide: Select the rotation direction that matches your motor or system requirements.
Port Orientation
Difference: WF8251009, WF8251014: Both outlets opposite inlet (180°); WF8251074, WF8251052: Both outlets inline with inlet (0°); WF8251091: Front outlet 90° CCW, rear outlet opposite (180°).
Selection Guide: Match port orientation to your plumbing layout. 180° is best for systems with straight-through lines; 0° or 90° may suit compact or complex installations.
Quick Selection Guide
If you need: The highest total flow (18.0 GPM) and higher-speed operation
Choose: WF8251074
Because: It offers 11 GPM front and 7 GPM rear at up to 2500 RPM, with a splined shaft for high-torque coupling.
If you need: A high main flow with a small auxiliary circuit
Choose: WF8251014 or WF8251052
Because: These provide 12 GPM front and 2 GPM rear, ideal for systems like Hi-Lo circuits, clamping functions, or similar multi-function applications.
If you need: Balanced flows for two similar circuits and high speed (up to 3000 RPM)
Choose: WF8251009
Because: It delivers 7 GPM front and 6 GPM rear at up to 3000 RPM, with a robust splined shaft.
If you need: A right-hand (CW) rotation pump with a high/low split and inline porting
Choose: WF8251052
Because: It combines 12 GPM front, 2 GPM rear, and 0° port orientation for compact installations.
If you need: Right-hand (CW) rotation with a 90° port for tight spaces
Choose: WF8251091
Because: The front outlet is 90° from the inlet, aiding installation in confined layouts.
Compatibility: All models are 100% interchangeable with Vickers V2020 pumps, mount with SAE ‘B’ 4-bolt flange, and use standard G1″/G1/2″ BSPP straight-thread ports. Volume pricing is available starting at 4 units, and each pump is covered by a 12-month manufacturer warranty.
