Product Selection Guide
These FluiDyne V20 Series vane pumps are all direct Vickers replacements, offering standardized SAE ‘A’ 2-bolt mounting and similar port sizes, but differ mainly in flow rate, displacement, shaft type, rotation, port orientation, and special cover features. Selecting the right model depends on your flow/pressure demands, shaft compatibility, rotation direction, and any need for integral flow control. For a full overview of available hydraulic pumps, explore our main product selection.
?? 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 |
|---|---|---|---|---|
| WF820487 (Current) | 9.4 GPM | 2500 PSI | 29.7 cm³/r (1.81 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820488 | 9.4 GPM | 2500 PSI | 29.7 cm³/r (1.81 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820481 | 9.4 GPM | 2500 PSI | 29.7 cm³/r (1.81 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820489 | 11.5 GPM | 2500 PSI | 36.3 cm³/r (2.22 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8201811 | 13.5 GPM | 2500 PSI | 42.6 cm³/r (2.60 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Flow Rate & Displacement
Difference: WF820487, WF820488, and WF820481 deliver 9–9.4 GPM at 1.81 in³/rev; WF820489 increases to 11.5 GPM at 2.22 in³/rev; WF8201811 delivers the highest at 13.5 GPM/2.60 in³/rev.
Selection Guide: For higher system demand, choose WF8201811 (13.5 GPM); for moderate demand, select WF820489 (11.5 GPM); for standard flows, use WF820487, WF820488, or WF820481.
Shaft Type
Difference: WF820487 and WF820481 use a 3/4″ straight keyed shaft; WF820488 and WF820489 have an 11-tooth splined shaft; WF8201811 uses a special shaft (Code 39).
Selection Guide: Use splined shaft models (WF820488, WF820489) for higher torque or spline couplings; straight keyed shaft models (WF820487, WF820481) suit standard keyed couplings.
Rotation Direction
Difference: WF820487, WF820488, WF820489 are left-hand (counter-clockwise); WF820481, WF8201811 are right-hand (clockwise).
Selection Guide: Match the rotation to your drive motor—select left-hand for counter-clockwise drives, right-hand for clockwise.
Port Orientation
Difference: WF820487, WF820488, WF8201811 have inline ports (0°); WF820481 has 90° clockwise ports; WF820489 has 90° counter-clockwise ports.
Selection Guide: Choose inline for straightforward plumbing; 90° ports suit installations with limited space or specific hose routing needs.
Pump Cover/Features
Difference: WF820489 features a flow control cover (includes relief valve and flow control); others have standard covers. For more options with integrated control, explore our pumps with integral valves.
Selection Guide: Use WF820489 when you need integrated flow and pressure control to simplify your circuit.
Maximum Pressure & Speed
Difference: Most models rated 2500 PSI and 2800 RPM max; WF8201811 maxes at 2200 PSI and 2400 RPM; WF820489 (with flow control) is limited to 2500 RPM.
Selection Guide: For highest pressure and speed demands, avoid WF8201811 and WF820489—choose other models for full 2500 PSI/2800 RPM operation.
Quick Selection Guide
If you need: Standard 9 GPM pump with left-hand rotation and keyed shaft
Choose: WF820487
Because: Matches most common Vickers V20 applications with direct interchangeability.
If you need: Standard 9 GPM, left-hand rotation, high-torque or splined coupling
Choose: WF820488
Because: Offers same performance as WF820487 but with a splined shaft for high-torque or spline couplings.
If you need: Standard 9 GPM, right-hand rotation, 90° port orientation
Choose: WF820481
Because: Best for systems needing clockwise rotation and side port configuration. Alternatively, for similar applications with slightly lower displacement, see our V201P8P10D11R model.
If you need: Higher flow (11.5 GPM), left-hand rotation, integrated flow control
Choose: WF820489
Because: Ideal for circuits that require controlled flow and built-in pressure relief.
If you need: Maximum flow (13.5 GPM), right-hand rotation
Choose: WF8201811
Because: Provides the highest output for demanding applications, with right-hand rotation. For related high-performance models, see the V201P13P3A11R pump.
Compatibility: All models are 100% interchangeable with Vickers V20 series, use SAE J744 ‘A’ 2-bolt mounting, G1″/G1/2″ BSPP ports, and fit standard hydraulic system footprints for easy integration.
