Product Selection Guide
These FluiDyne V2020 double vane pump models differ mainly in their front/rear pump flow combinations, rotation direction, shaft type, port orientation, and maximum speed. Compare with our V201P5P18C11R – FluiDyne V20 Pump for similar specs in single-section configurations. All are direct Vickers replacements, offer up to 2500 PSI, and share SAE ‘A’ mounting and G1″/G1/2″ BSPP ports, ensuring easy interchangeability. Choosing the best model depends on your system’s required total flow, rotation direction, and installation constraints. For more options in multi-circuit and single-stage setups, review our collection of vane pumps.
?? 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 |

| WF8251134 (Current) | 13 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8251121 | 10 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825111 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF825115 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |

Key Differences
Front/Rear Pump Flow (Total Flow)
Difference: WF8251134 and WF825116 both deliver 19.0 GPM total (WF8251134: 13+6 GPM, WF825116: 11+8 GPM), WF8251121 provides 15.0 GPM (10+5 GPM), WF825111 and WF825115 offer 12.0 GPM (11+1 GPM each).
Selection Guide: Choose a higher total flow model (WF8251134 or WF825116) for applications demanding more hydraulic power or dual circuits with higher flow needs. Select lower flow models for smaller actuators or systems with modest requirements.
Maximum Speed
Difference: WF825116: 2500 RPM, WF8251134: 2400 RPM, WF8251121: 1800 RPM, WF825111/WF825115: 1800 RPM (limited by rear pump).
Selection Guide: Select WF825116 or WF8251134 if your application requires higher pump speeds. Use WF8251121, WF825111, or WF825115 for lower-speed systems.
Rotation Direction
Difference: WF8251134, WF825115, WF825116 are right-hand (clockwise); WF8251121, WF825111 are left-hand (counter-clockwise).
Selection Guide: Match the pump rotation to your prime mover or existing system—choose right-hand for clockwise drive, left-hand for counter-clockwise.
Shaft Type
Difference: WF8251134, WF825111, WF825115, WF825116 use 13-tooth splined shafts (except WF8251121: straight keyed shaft).
Selection Guide: Select splined shafts for high-torque or flexible coupling systems; choose straight keyed (WF8251121) for standard keyed couplings. If your application requires higher displacement, consider the V201P13P3A11R – FluiDyne V20 Pump.
Port Orientation
Difference: WF8251134, WF825116: both outlets 90° CCW from inlet; WF825115: both outlets 90° CW; WF825111: both outlets 180° (opposite) from inlet; WF8251121: front outlet 180°, rear inline (0°).
Selection Guide: Use 90° port orientation for tight installations or side exits; 180° for direct, straight connections.
Quick Selection Guide
If you need: Highest total flow with balanced front/rear outputs and high speed
Choose: WF825116 (11+8 GPM, up to 2500 RPM, right-hand, 90° CCW ports)
Because: Ideal for dual circuits needing substantial flow to both sides at higher speeds.
If you need: Highest front section flow and high speed
Choose: WF8251134 (13+6 GPM, up to 2400 RPM, right-hand, 90° CCW ports)
Because: Best when primary circuit needs maximum flow, with moderate rear circuit demand.
If you need: Lower total flow and left-hand (counter-clockwise) rotation
Choose: WF8251121 (10+5 GPM, up to 1800 RPM, straight keyed shaft, front/rear ports at 180°/0°)
Because: Suited for systems where space or drive configuration requires left-hand rotation.
If you need: Compact flow with matched left-hand rotation and splined shaft
Choose: WF825111 (11+1 GPM, up to 1800 RPM, splined, both ports 180°)
Because: For applications with minimal secondary flow and specific porting/rotation needs.
If you need: Compact flow with right-hand rotation and 90° CW ports
Choose: WF825115 (11+1 GPM, up to 1800 RPM, splined, both ports 90° CW)
Because: For installations requiring clockwise rotation and ports exiting to the side.
Compatibility: All models are direct Vickers replacements, 100% interchangeable, follow SAE ‘A’ mounting, and use G1″/G1/2″ BSPP straight thread ports. For more information about compatible alternatives, see our Vickers replacement pumps page. All support up to 2500 PSI and are covered by a 12-month warranty. Volume pricing is available starting at 4 units. Same-day shipping is offered on in-stock items.
