Product Selection Guide
These Fluidyne V20 Series hydraulic vane pumps are all single stage vane pumps as direct Vickers replacements with 100% interchangeability, following SAE ‘A’ 2-bolt mounting and G1″/G1/2″ BSPP port standards. The main differences lie in flow rate, displacement, shaft type, port orientation, rotation direction, and specialized covers such as flow control. Selecting the right model depends on your required flow, available system pressure, port configuration, shaft compatibility, and control needs.
?? 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 |
|---|---|---|---|---|
| WF820552 (Current) | 8.4 GPM | 2500 PSI | 26.6 cm³/r (1.62 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820556 | 5.7 GPM | 2500 PSI | 18.0 cm³/r (1.10 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820553 | 11.5 GPM | 2500 PSI | 36.3 cm³/r (2.22 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820551 | 12.5 GPM | 2500 PSI | 39.5 cm³/r (2.41 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF820559 | 6.2 GPM | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Flow Rate
Difference: Models offer flow rates from 5.7 GPM (WF820556) up to 12.5 GPM (WF820551) at 1200 RPM.
Selection Guide: Choose higher GPM models, like WF820551 (12.5 GPM), for large actuators or higher system speeds; opt for WF820556 (5.7 GPM) for smaller cylinders or slower operation.
Displacement
Difference: Displacement ranges from 18.0 cm³/r (1.10 in³/r, WF820556) to 39.5 cm³/r (2.41 in³/r, WF820551).
Selection Guide: Select larger displacements for systems requiring more oil per revolution or larger volume per cycle.
Shaft Type and Extension
Difference: Most models use a 3/4″ straight shaft with key (1.75″ extension), while WF820552 and WF820559 list an 11-tooth splined shaft (with different extensions).
Selection Guide: Choose the straight keyed shaft for standard couplings; select splined shafts for high-torque or precision couplings.
Port Position
Difference: Port orientation varies: inline with inlet (0°, WF820556, WF820559), opposite from inlet (180°, WF820552, WF820551), and 90° clockwise from inlet (WF820553).
Selection Guide: Select port orientation based on plumbing layout—inline for straight-through piping, 90° or opposite for compact or custom installations.
Rotation Direction
Difference: Most models are right-hand (clockwise), but WF820551 and WF820559 are left-hand (counter-clockwise).
Selection Guide: Match pump rotation to your existing drive—right-hand for standard, left-hand for reverse rotation setups.
Special Covers & Controls
Difference: WF820559 includes a flow control cover (6 GPM) and relief valve (2000 PSI); all others have standard covers.
Selection Guide: Choose WF820559 if you need integrated flow control or pressure relief in one compact unit.
Maximum Pressure & Speed
Difference: Most models are rated for 2500 PSI; maximum speed varies (WF820556: 3000 RPM, WF820553: 2500 RPM, others up to 2800 RPM).
Selection Guide: Use higher speed models for faster cycling systems; always check your application’s max pressure and speed requirements.
Quick Selection Guide
If you need: Low flow for compact circuits (under 6 GPM)
Choose: WF820556 (5.7 GPM, 1.10 in³/r, right-hand, inline ports)
Because: Best suited for small actuators or low-speed operation; high max speed (3000 RPM) allows flexibility.
If you need: Medium flow and standard controls (8–12 GPM)
Choose: WF820552 (8.4 GPM, 1.62 in³/r, right-hand, 180° ports, splined shaft) or V201P8P10D11R – FluiDyne V20 Pump (26.6 cm³/r, 1.62 in³/r) or WF820553 (11.5 GPM, 2.22 in³/r, right-hand, 90° ports)
Because: Ideal for typical industrial equipment; select port orientation and shaft type to match your installation.
If you need: Highest displacement/flow in this range
Choose: WF820551 (12.5 GPM, 2.41 in³/r, left-hand, 180° ports)
Because: Suited for large cylinders or systems requiring maximum volume; verify left-hand rotation compatibility.
If you need: Integrated flow control and relief protection
Choose: WF820559 (6.2 GPM, 1.19 in³/r, left-hand, inline ports, flow control cover)
Because: Offers built-in 6 GPM flow control and 2000 PSI relief valve—useful for circuits where external valves are limited.
Compatibility: All models are Vickers replacement pumps with SAE J744 ‘A’ 2-bolt mounting and G1″/G1/2″ BSPP ports. All are 100% interchangeable with Vickers models, ensuring easy retrofit or replacement.
