Looking for more hydraulic pumps? Northern Hydraulics offers a full range of proven solutions for industrial and mobile applications, with 40+ years of field experience and customer success stories.
These FluiDyne V20 Series vane pumps are all direct Vickers replacements, featuring the same SAE ‘A’ 2-bolt flange mounting and G1″/G1/2″ BSPP porting for straightforward interchangeability. The key differences are in flow rate, displacement, pressure rating, port/thread style, shaft configuration, and port orientation. Selection depends on your system’s required flow, available mounting, port thread compatibility, and shaft/coupling needs. For more detailed specifications, browse our single stage vane pumps for additional options and technical resources.
?? 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 |
|---|---|---|---|---|
| WF8202261 (Current) | 6.2 GPM | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8202297 | 13.5 GPM | 2500 PSI | 42.6 cm³/r (2.60 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820229 | 13.5 GPM | 2500 PSI | 42.6 cm³/r (2.60 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8202267 | 6.2 GPM | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820228 | 8.4 GPM | 2500 PSI | 26.6 cm³/r (1.62 in³/r) | 2-Bolt Flange (SAE “A” size) |
Difference: Flow rates range from 6.2 GPM (1.19 in³/rev) to 13.5 GPM (2.60 in³/rev).
Selection Guide: Select higher GPM/displacement models (WF820229, WF8202297) for systems needing faster actuator movement or higher volume. Choose lower GPM/displacement (WF8202261, WF8202267) for smaller circuits or more precise control.
Difference: All models are rated up to 2500 PSI, except the base descriptions for WF820229/WF8202297 show 2200 PSI (but specs list 2500 PSI). Max speed varies: 2400–3000 RPM.
Selection Guide: Pick models with higher RPM ratings (WF8202261, WF8202267) for high-speed drives. For standard pressure needs, any model is suitable.
Difference: Some models have NPT threads, others BSPP. Port positions are either opposite from inlet (180°) or inline (0°).
Selection Guide: Choose matching port threads for your plumbing (NPT or BSPP). Inline ports (WF8202297) suit straight-through plumbing; opposite ports (others) work where right-angle connections are preferred.
Difference: Some models use a standard 3/4″ straight keyed shaft, others have a special (Code 15) shaft; shaft extension length varies slightly.
Selection Guide: Standard keyed shaft fits most couplings. If your system requires a specific shaft, match the code and extension length.
If you need: Highest flow (13.5 GPM) for large cylinders or rapid cycling
Choose: V201P13P39C11R or WF8202297
Because: These offer the highest displacement (2.60 in³/rev) and flow at 1200 RPM.
If you need: Medium flow (8.4 GPM) with standard mounting and ports
Choose: WF820228
Because: Balances flow and displacement (1.62 in³/rev) for mid-sized applications.
If you need: Compact flow (6.2 GPM) for precision circuits or lower volume systems
Choose: WF8202261 or WF8202267
Because: Lowest displacement (1.19 in³/rev) and flow for small actuators or fine control.
If you need: Inline port orientation for streamlined plumbing
Choose: WF8202297
Because: Port position is inline (0°), minimizing bends in piping.
If you need: Special shaft configuration
Choose: WF8202297 or WF8202267
Because: These models note a ‘special shaft (Code 15)’, check if your coupling requires this.
Compatibility: All models are 100% interchangeable with Vickers replacement pumps and follow SAE J744 mounting—ensuring direct drop-in replacement. BSPP and NPT porting options available.
