Product Selection Guide

These FluiDyne V20 Series hydraulic vane pumps all offer direct Vickers interchangeability and are built to SAE J744 standards, but differ in flow rate, displacement, max speed, port orientation, shaft type, rotation, and inlet/outlet sizing. Choosing the right model depends on system flow demand, piping layout, available mounting space, and drive direction. For a broader selection, see our hydraulic pumps catalog.

?? 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
WF8201139 (Current)	5.7 GPM	2500 PSI	18.0 cm³/r (1.10 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201138	13.5 GPM	2500 PSI	42.6 cm³/r (2.60 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201144	8.4 GPM	2500 PSI	26.6 cm³/r (1.62 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201179	9.4 GPM	2500 PSI	29.7 cm³/r (1.81 in³/r)	2-Bolt Flange (SAE “A” size)

Key Differences

Flow Rate & Displacement

Difference: WF8201138 offers the highest flow (13.5 GPM, 2.60 in³/r); WF8201139 is lowest (5.7 GPM, 1.10 in³/r); WF8201144, WF8201171 (8.4 GPM, 1.62 in³/r), WF8201179 (9.4 GPM, 1.81 in³/r)

Selection Guide: Select higher displacement/flow models for systems with large actuators or multiple functions; use lower flow models for compact or lower-demand systems

Max Speed

Difference: WF8201139/1138 rated for 1200 RPM, WF8201144/1171/1179 up to 2800 RPM

Selection Guide: Choose WF8201144, WF8201171, or WF8201179 for high-speed drive applications

Rotation

Difference: WF8201179 is Left-Hand (Counter-Clockwise); other models are Right-Hand (Clockwise)

Selection Guide: Choose WF8201179 when your prime mover requires counter-clockwise pump rotation

Port Orientation

Difference: WF8201139/1138 have ports inline with inlet (0°); others are opposite (180°)

Selection Guide: Inline (0°) orientation suits straight-through piping; 180° is preferred if piping must exit on opposite sides

Shaft Type and Extension

Difference: WF8201139 has 9-tooth splined shaft; others use 3/4″ straight keyed shaft, with extension lengths varying (1.75″ or 2.66″). For a similar 18.0 cm³/r (1.10 in³/r) option, see V201P5P18C11R – FluiDyne V20 Pump.

Selection Guide: Select the splined shaft for higher-torque or splined coupler drives; straight shaft for standard keyed coupling

Inlet/Outlet Thread Size

Difference: WF8201139/1138/1144: 1-1/4″ NPT inlet; WF8201171: 1″ NPT inlet; WF8201179: 1-1/4″ NPT inlet. Outlet is typically 3/4″ NPT except WF8201179 (1-1/16″-12 straight)

Selection Guide: Match inlet/outlet size to your system piping to minimize flow restriction

Quick Selection Guide

If you need: Highest flow for large or multi-cylinder systems (over 9 GPM)

Choose: WF8201138

Because: Delivers 13.5 GPM at 1200 RPM, highest in this group

If you need: Compact flow and lower displacement for controlled motion or low-demand circuits

Choose: WF8201139

Because: Provides 5.7 GPM at 1.10 in³/r, minimizing heat and energy use

If you need: Medium flow with high drive speed (up to 2800 RPM)

Choose: WF8201144, WF8201171, or WF8201179

Because: Rated for 8.4–9.4 GPM and higher RPM, ideal for faster driven systems

If you need: Left-Hand (CCW) rotation for reverse drive applications

Choose: WF8201179

Because: Specifically designed for counter-clockwise rotation

If you need: Inline ports for straightforward plumbing

Choose: WF8201139 or WF8201138

Because: Feature 0° port orientation for simple pipe routing

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

Choose: WF8201139

Because: Only model in this group with 9-tooth splined shaft

Compatibility: All models meet SAE J744 mounting and are 100% Vickers interchangeable. G1″/G1/2″ BSPP straight thread ports and 2-bolt SAE ‘A’ flanges are consistent for easy replacement and integration.
