Product Selection Guide

These five FluiDyne V20 Series hydraulic vane pumps are direct Vickers replacements, sharing the same SAE ‘A’ 2-bolt flange mounting, pressure rating (2500 PSI), and similar speed capabilities, but differ in flow rate, displacement, shaft type, port orientation, and rotation direction. For more detailed series options, see V201P13P39C11R – FluiDyne V20 Pump (2.60 in³/r) and V201P8P10D11R – FluiDyne V20 Pump (1.62 in³/r). Selection should be based on required system flow, shaft compatibility, port arrangement, and motor rotation.

?? 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
WF8201421 (Current)	9.4 GPM	2500 PSI	29.7 cm³/r (1.81 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201410	6.2 GPM	2500 PSI	19.5 cm³/r (1.19 in³/r)	2-Bolt Flange (SAE “A” size)
WF820149	6.2 GPM	2500 PSI	19.5 cm³/r (1.19 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201412	8.4 GPM	2500 PSI	26.6 cm³/r (1.62 in³/r)	2-Bolt Flange (SAE “A” size)

Key Differences

Flow Rate & Displacement

Difference: WF8201410 offers the lowest flow (6.2 GPM, 1.19 in³/r); WF8201421 is the highest (9.4 GPM, 1.81 in³/r); WF8201412 and WF8201424 are mid-range (8.4 GPM, 1.62 in³/r); WF820149 offers 7 GPM (1.39 in³/r).

Selection Guide: Select higher displacement (WF8201421) for faster cycling or larger actuators; choose lower displacement (WF8201410) where precise, lower flow is needed.

Shaft Type

Difference: WF8201421, WF8201410, and WF8201412 use a 3/4″ straight keyed shaft; WF820149 and WF8201424 use an 11-tooth splined shaft.

Selection Guide: Use splined shaft models (WF820149, WF8201424) for high-torque or splined coupling systems; keyed shaft models for standard couplings.

Port Position

Difference: WF8201421, WF820149, WF8201412 all have ports inline with the inlet (0°); WF8201410 has ports at 90° counter-clockwise; WF8201424 has ports opposite the inlet (180°).

Selection Guide: Choose inline port models for straightforward plumbing; 90° or 180° ports (WF8201410, WF8201424) for tight or custom installation layouts.

Rotation Direction

Difference: WF8201421, WF8201410, WF820149, and WF8201412 are right-hand (clockwise); WF8201424 is left-hand (counter-clockwise).

Selection Guide: Match pump rotation to your drive motor: right-hand for standard clockwise drives; left-hand (WF8201424) for counter-clockwise systems.

Port Thread Type

Difference: WF8201421, WF8201412, and WF8201424 have 1″ NPT inlet/3/4″ NPT outlet; WF8201410 and WF820149 offer 1-1/4″ NPT and alternate outlet threads.

Selection Guide: Verify port size and thread type for compatibility with your hydraulic lines; larger inlets (WF8201410, WF820149) suit higher suction requirements.

Maximum Speed

Difference: WF8201410 has the highest max speed (3400 RPM); WF8201421, WF8201412, WF8201424 are rated to 2800 RPM; WF820149 to 3000 RPM.

Selection Guide: Select higher speed models (WF8201410) for variable speed drives or high-RPM applications.

Quick Selection Guide

If you need: Highest flow and displacement for fast cycling or larger actuators

Choose: WF8201421

Because: Delivers 9.4 GPM at 1200 RPM and 1.81 in³/r displacement.

If you need: Compact flow for precise control or smaller cylinders

Choose: WF8201410

Because: Lowest displacement (1.19 in³/r) and highest rated speed (3400 RPM).

If you need: Splined shaft for high-torque or splined coupling applications

Choose: WF820149 or WF8201424

Because: Both offer 11-tooth splined shafts, with different port positions and rotation.

If you need: Left-hand (counter-clockwise) rotation

Choose: WF8201424

Because: Only model in this group with left-hand rotation.

If you need: Ports at 90° for installation flexibility

Choose: WF8201410

Because: Inlet and outlet are positioned 90° counter-clockwise from each other.

Compatibility: All models are 100% interchangeable with Vickers V20 series, use SAE ‘A’ 2-bolt flange mounting, and are rated to 2500 PSI.
