Product Selection Guide
These FluiDyne V2020 double vane pump models are all direct Vickers replacements, but they differ in flow output per section, overall flow, shaft style, port orientation, rotation direction, and maximum speed. These variations allow you to match the pump closely to your circuit’s flow demands, mounting, and installation constraints.
?? 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 |

| 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) |

Key Differences
Front/Rear Pump Flow Rate & Total Flow
Difference: WF8251045 delivers 7 GPM (front) + 7 GPM (rear) = 14 GPM total; WF8251091 provides 11 GPM (front) + 6 GPM (rear) = 17 GPM total; WF8251074 outputs 11 GPM (front) + 7 GPM (rear) = 18 GPM total; WF8251014 and WF8251052 offer 12 GPM (front) + 2 GPM (rear) = 14 GPM total.
Selection Guide: Choose higher total flow models (WF8251074: 18 GPM, WF8251091: 17 GPM) for circuits requiring greater volume, or opt for 12+2 GPM splits (WF8251014, WF8251052) if you need high primary flow with minimal secondary flow. See our complete range of vane pumps for more selection guidance.
Maximum Speed
Difference: WF8251045 and WF8251074: 3000 RPM max; WF8251091: 2500 RPM max; WF8251014 and WF8251052: 1800 RPM max.
Selection Guide: Select WF8251045 or WF8251074 where higher pump speed is necessary; use WF8251014 or WF8251052 for lower-speed applications.
Rotation Direction
Difference: WF8251045, WF8251074, WF8251014: Left-Hand (CCW); WF8251091, WF8251052: Right-Hand (CW).
Selection Guide: Match pump rotation to your drive—select left-hand for CCW, right-hand for CW shafts.
Shaft Type
Difference: WF8251074 uses a 13-tooth splined shaft; all others use a straight keyed shaft.
Selection Guide: Select splined shaft (WF8251074) for high torque or splined couplings; use straight keyed for standard couplings.
Port Orientation
Difference: WF8251045: outlets 90° CW from inlet; WF8251091: front 90° CCW, rear 180°; WF8251074: both inline (0°); WF8251014: both 180° (opposite inlet); WF8251052: both inline (0°).
Selection Guide: Choose port orientation for ease of plumbing—inline ports (WF8251074, WF8251052) simplify straight-line connections, while 90° or 180° orientations can solve tight-space or specific manifold layouts.
Displacement
Difference: WF8251045: 2 x 1.39 in³/rev; WF8251091: 2.22 + 1.19 in³/rev; WF8251074: 2.22 + 1.39 in³/rev; WF8251014 & WF8251052: 2.41 + N/A in³/rev.
Selection Guide: Higher displacement supports higher flow at lower RPM. For applications needing steady flow at low speeds, prioritize models with larger displacement per rev.
Port Threads
Difference: Pump bodies all offer G1″/G1/2″ BSPP threads.
Selection Guide: All models fit standard BSPP hydraulic plumbing.
Quick Selection Guide
If you need: Balanced dual flow for equal circuits (e.g., two actuators with similar demand)
Choose: WF8251045
Because: Both front and rear pumps provide 7 GPM at up to 3000 RPM, suitable for parallel operation.
If you need: Higher total flow with a higher primary circuit demand
Choose: WF8251074 (11 + 7 GPM, splined shaft) or WF8251091 (11 + 6 GPM, keyed shaft)
Because: They offer more total flow, ideal for systems with a primary actuator and a secondary lower-demand circuit.
If you need: Maximum flow to one section with minimal flow to the other (e.g., high/low circuit)
Choose: WF8251014 (left-hand, inline 180° ports) or WF8251052 (right-hand, inline 0° ports)
Because: These provide 12 GPM to the front pump and 2 GPM to the rear, optimizing for a main function with a low-flow auxiliary.
If you need: High-torque drive compatibility
Choose: WF8251074
Because: Uses a 13-tooth splined shaft for improved torque transmission.
If you need: Specific port orientation to suit tight installation or manifold requirements
Choose: WF8251074 or WF8251052 for inline ports, WF8251045 for 90° CW, WF8251091 for mixed orientation, WF8251014 for 180°
Because: Matching port orientation reduces plumbing complexity and potential for leaks.
Compatibility: All models feature SAE ‘B’ 4-bolt flange mounting and G1″/G1/2″ BSPP ports, ensuring direct interchangeability with Vickers V2020 models and seamless integration into existing systems.
