Product Selection Guide
The FluiDyne V20 Series models listed here are all direct Vickers replacements, sharing SAE ‘A’ 2-bolt flange mounting and G1″/G1/2″ BSPP ports for seamless interchangeability. Their key differences are flow rate, displacement, shaft type, port position, rotation, and cover design. Selection should focus on flow requirements, shaft/coupling compatibility, preferred port orientation, and maximum pressure ratings.
?? 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 |
|---|---|---|---|---|
| WF820858 (Current) | 9.4 GPM | 2500 PSI | 29.7 cm³/r (1.81 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820852 | 6.2 GPM | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820850 | 6.2 GPM | 2500 PSI | 19.5 cm³/r (1.19 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) |
| WF8201212 | 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: WF820858 and WF820850 offer 9.4 GPM at 1.81 in³/rev, WF820852 provides 6.2 GPM at 1.19 in³/rev, WF8201811 and WF8201212 deliver 13.5 GPM at 2.60 in³/rev.
Selection Guide: Choose higher displacement models (WF8201811, WF8201212) for faster actuator speeds or larger cylinders; select WF820852 for lower-flow, precision tasks.
Maximum Pressure Rating
Difference: All models rated up to 2500 PSI except WF8201811 and WF8201212, which specify 2200 PSI in descriptions but 2500 PSI in specs.
Selection Guide: For pressures above 2200 PSI, verify application and consult specs; most models support up to 2500 PSI.
Shaft Type
Difference: WF820858, WF820852: 3/4″ straight shaft with key; WF820850: 11-tooth splined shaft (1.25″ extension); WF8201212: 7/8″ threaded shaft with Woodruff key; WF8201811: special (code 39) shaft.
Selection Guide: Select splined or threaded shafts for high-torque or specific coupling needs; straight keyed for standard couplings.
Port Position
Difference: WF820858, WF8201811: inlet and outlet inline (0°); WF820852, WF8201212: ports opposite (180°); WF820850: outlet at 90° clockwise from inlet.
Selection Guide: Inline ports simplify straight plumbing runs; 90° or 180° suited for space-constrained or offset layouts.
Rotation
Difference: WF820858, WF820850: left-hand (CCW); WF820852, WF8201811, WF8201212: right-hand (CW).
Selection Guide: Match pump rotation to your drive motor’s direction for proper operation.
Cover/Valve Options
Difference: WF820850 features a flow control cover with integral relief valve (2000 PSI), others use standard covers. For more options, view our pumps with integral valves category.
Selection Guide: Choose flow control/relief cover for circuits needing built-in pressure/flow management.
Max Speed
Difference: WF820858, WF820850: up to 2800 RPM; WF820852: 3000 RPM; WF8201811, WF8201212: 2400 RPM.
Selection Guide: Select higher speed models for high-RPM drives; lower speed for larger displacement units.
Quick Selection Guide
If you need: Moderate flow (9.4 GPM), left-hand rotation, standard shaft, inline ports
Choose: WF820858
Because: Ideal for standard Vickers V20 replacement where 9 GPM at 1200 RPM is required.
If you need: Lower flow (6.2 GPM), right-hand rotation, opposite port orientation
Choose: WF820852
Because: Suited for smaller actuators or precise control, with 1.19 in³/rev displacement.
If you need: Moderate flow (9 GPM), left-hand rotation, splined shaft, 90° port orientation, built-in flow control and relief
Choose: WF820850
Because: Best for high-torque drives and circuits needing integrated pressure/flow management.
If you need: High flow (13.5 GPM), right-hand rotation, inline or opposite port orientation
Choose: WF8201811 (inline ports, special shaft) or WF8201212 (opposite ports, threaded shaft)
Because: Provide maximum flow for large cylinders or faster cycles; choose shaft/port to match installation.
Compatibility: All models are direct Vickers replacements, 100% interchangeable, and use SAE J744 mounting with standard BSPP ports for straightforward retrofits. Browse our single stage vane pumps applications for additional configurations.
