Product Selection Guide

These FluiDyne V20 Series hydraulic vane pumps are all direct Vickers replacements, but differ primarily in flow rate, displacement, shaft type, port orientation, and rotation. All models share SAE ‘A’ 2-bolt flange mountings and G1″/G1/2″ BSPP straight thread ports, ensuring full interchangeability within our full vane pumps range. Selection depends on required system flow, pressure, shaft compatibility, and rotation direction. For a complete overview of our hydraulic pumps selection, visit our main category.

?? 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
WF8201179 (Current)	9.4 GPM	2500 PSI	29.7 cm³/r (1.81 in³/r)	2-Bolt Flange (SAE “A” size)
V201P13P39C11R – FluiDyne V20 Pump (42.6 cm³/r)	13.5 GPM	2500 PSI	42.6 cm³/r (2.60 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201139	5.7 GPM	2500 PSI	18.0 cm³/r (1.10 in³/r)	2-Bolt Flange (SAE “A” size)
V201P8P10D11R – FluiDyne V20 Pump (26.6 cm³/r)	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: WF8201139 delivers the lowest flow at 5.7 GPM (1.10 in³/r), while WF8201138 offers the highest at 13.5 GPM (2.60 in³/r). WF8201179, WF8201144, and WF8201171 provide intermediate flows from 8.4 to 9.4 GPM (1.62–1.81 in³/r).

Selection Guide: Select WF8201138 for higher volume circuits, WF8201139 for compact/low flow applications, and WF8201179, WF8201144, or WF8201171 for medium flow needs.

Shaft Type & Size

Difference: WF8201139 uses a 9-tooth splined shaft (1.25″ ext.), WF8201138 a threaded shaft with Woodruff key, while the others use a 3/4″ straight keyed shaft (1.75–2.66″ ext.).

Selection Guide: Choose splined (WF8201139) for high-torque or splined-coupling systems; threaded (WF8201138) for compatibility with threaded couplings; straight keyed for standard couplings.

Port Position

Difference: WF8201179, WF8201144, and WF8201171 have outlets opposite the inlet (180°), while WF8201138 and WF8201139 have inline ports (0°).

Selection Guide: Opt for inline (0°) when inlet/outlet are on the same side for easy hose routing; choose 180° when ports need to be on opposite sides for system layout.

Rotation

Difference: WF8201179 is left-hand (CCW), others are right-hand (CW).

Selection Guide: Select pump rotation to match your system drive direction—incorrect rotation may cause pump failure.

Maximum Speed

Difference: WF8201139 supports up to 3000 RPM, while the rest are rated to 2400–2800 RPM.

Selection Guide: Use WF8201139 in higher-speed applications needing lower flow.

Inlet/Outlet Thread Type

Difference: WF8201171 uses a 1″ NPT inlet, others use 1-1/4″ NPT; outlet varies between 3/4″ NPT and 1-1/16″-12 straight thread.

Selection Guide: Match thread type and size to your existing plumbing for easy installation.

Quick Selection Guide

If you need: Highest flow at 1200 RPM (13.5 GPM)

Choose: WF8201138

Because: Delivers maximum volume, ideal for large actuators or fast cycling systems.

If you need: Compact, low-flow with high-speed capability

Choose: WF8201139

Because: Lowest displacement and highest max speed (3000 RPM), with splined shaft for high-torque.

If you need: Medium flow with left-hand (CCW) rotation

Choose: WF8201179

Because: 9.4 GPM, 1.81 in³/r, and left-hand rotation for specialized system requirements.

If you need: Medium flow, right-hand (CW), standard shaft, 180° ports

Choose: WF8201144 or WF8201171

Because: Both provide 8.4 GPM, straight keyed shaft, and opposite port layout for typical layouts.

Compatibility: All models are 100% interchangeable with Vickers V20 pumps, using SAE J744 ‘A’ 2-bolt mounting and standard BSPP ports, simplifying swap-outs and upgrades. For further product options, see our full Vickers replacement pump lineup.
