Product Selection Guide

The FluiDyne V20 Series models compared here differ primarily by flow rate, displacement per revolution, shaft configuration, port orientation, and rotation direction. All models are direct Vickers replacements with SAE ‘A’ 2-bolt flange mounting, 2500 PSI max pressure, and G1″/G1/2″ BSPP ports—making them 100% interchangeable in most applications.

?? 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
WF8201451 (Current)	11.5 GPM	2500 PSI	36.3 cm³/r (2.22 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)
WF8201424	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: Flow rates at 1200 RPM range from 6.2 GPM (WF8201410) up to 11.5 GPM (WF8201451), with corresponding displacement from 1.19 in³/r to 2.22 in³/r.

Selection Guide: Select higher displacement models (WF8201451) for systems requiring more hydraulic flow, such as larger actuators or quicker cycle times. Lower displacement models (WF8201410) are suitable for smaller systems with lower flow demand.

Shaft Configuration

Difference: Models offer 3/4″ straight keyed shafts (WF8201410, WF8201412) or 11-tooth splined shafts (WF820149, WF8201424), with some special shaft codes (WF8201451: Code 15; WF8201412: Code 23).

Selection Guide: Choose straight keyed shafts for standard couplings; opt for splined shafts in high-torque or heavy-duty applications. Match the shaft type to your coupling and torque requirements.

Port Position

Difference: WF8201451 and WF8201410 have ports at 90° counter-clockwise from inlet; WF820149 and WF8201412 have inline (0°) ports; WF8201424 has ports opposite (180°) from inlet.

Selection Guide: Select the port orientation that best fits your plumbing layout: 90° for compact installations, inline for straight-through connections, or 180° for opposite-side porting.

Rotation Direction

Difference: WF8201451, WF8201410, WF820149, and WF8201412 are right-hand (clockwise) rotation; WF8201424 is left-hand (counter-clockwise) rotation.

Selection Guide: Match pump rotation with your system drive. Left-hand rotation (WF8201424) is required for specific reverse-rotation applications.

Maximum Speed

Difference: WF8201410 operates up to 3400 RPM, WF820149 up to 3000 RPM, WF8201412 and WF8201424 up to 2800 RPM, WF8201451 up to 2500 RPM.

Selection Guide: For high-speed operation, select WF8201410. For normal speeds (up to 1200 RPM), any model is suitable.

Quick Selection Guide

If you need: Highest flow rate (11.5 GPM at 1200 RPM)

Choose: WF8201451

Because: Best for larger hydraulic systems or faster actuator movement.

If you need: Moderate flow with standard shaft and right-hand rotation

Choose: WF8201412 (8.4 GPM, 0° port position) or WF8201410 (6.2 GPM, 90° port position)

Because: Ideal for mid-size systems with standard plumbing layouts.

If you need: Splined shaft for high-torque coupling

Choose: WF820149 (7 GPM, right-hand, 0° ports) or WF8201424 (8 GPM, left-hand, 180° ports)

Because: Ensures reliable performance in demanding applications.

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

Choose: WF8201424

Because: Only model in this group designed for reverse rotation systems.

If you need: Maximum speed capability (up to 3400 RPM)

Choose: WF8201410

Because: Suited for high-speed pump drive applications.

Compatibility: All models are 100% Vickers interchangeable, use SAE ‘A’ 2-bolt flange mounting, and G1″/G1/2″ BSPP straight thread ports for seamless system integration.
