Product Selection Guide

These FluiDyne V20 Series single stage vane pumps are all direct Vickers replacements, sharing SAE ‘A’ 2-bolt flange mounting and BSPP porting for straightforward interchangeability. Their main differences are flow capacity, displacement, shaft type, rotation, port orientation, and certain connection details—each influencing suitability for specific hydraulic system requirements.

?? Important: The specifications shown are for reference and comparison purposes. For more options, see our full range of hydraulic pumps. 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
WF8201116 (Current)	11.5 GPM	2500 PSI	36.3 cm³/r (2.22 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)
WF8201139	5.7 GPM	2500 PSI	18.0 cm³/r (1.10 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

Difference: Models range from 5.7 GPM (WF8201139) up to 13.5 GPM (WF8201138) at 1200 RPM.

Selection Guide: Select higher flow models (WF8201138) for systems requiring faster actuator movement or greater hydraulic output; choose lower flow models (WF8201139) for applications needing precise, lower volume control.

Displacement

Difference: Displacement varies from 18.0 cm³/r (1.10 in³/r, WF8201139) to 42.6 cm³/r (2.60 in³/r, WF8201138).

Selection Guide: Larger displacement (WF8201138) delivers more volume per revolution—ideal for high-output circuits. Smaller displacement (WF8201139) is best for fine control or low-demand functions.

Shaft Type and Size

Difference: Models offer either a 9-tooth splined shaft (WF8201116, WF8201139), a 3/4″ straight shaft with key (all models), or a 7/8″ threaded shaft with Woodruff key (WF8201138 only).

Selection Guide: Choose splined shafts (WF8201116, WF8201139) for higher torque and robust coupling; threaded shafts (WF8201138) may suit retrofits; straight keyed shafts are standard and widely compatible.

Rotation

Difference: WF8201116 and WF8201179 are left-hand (counter-clockwise), the others are right-hand (clockwise).

Selection Guide: Match pump rotation to your drive direction—incorrect rotation will prevent operation.

Port Position

Difference: WF8201116 has ports at 90° clockwise from inlet; WF8201139 and WF8201138 have inline ports (0°); WF8201144 and WF8201179 have ports opposite (180°) from inlet.

Selection Guide: Choose port positions that best fit your plumbing layout to minimize hose bends and installation space.

Maximum Pressure and Speed

Difference: All models rated to 2500 PSI; maximum speeds range from 2400 to 3000 RPM. For detailed technical specifications, visit our vane pumps applications resource page.

Selection Guide: If your application runs at higher RPMs, select models like WF8201139 (3000 RPM).

Quick Selection Guide

If you need: Highest flow and displacement (13.5 GPM, 2.60 in³/r) at 1200 RPM

Choose: WF8201138

Because: It delivers maximum output among these models and suits high-demand systems.

If you need: Most compact, low-flow solution (5.7 GPM, 1.10 in³/r)

Choose: WF8201139

Because: It’s ideal for precise, low-volume circuits and allows up to 3000 RPM operation.

If you need: Intermediate flow (9.4 GPM, 1.81 in³/r) with left-hand rotation

Choose: WF8201179

Because: It offers moderate volume and left-hand rotation for compatible drives.

If you need: Mid-range flow (8.4 GPM, 1.62 in³/r) with right-hand rotation and 180° porting

Choose: WF8201144

Because: It balances size and output, suitable for installations needing opposite port orientation.

If you need: Standard left-hand rotation with splined shaft (11.5 GPM, 2.22 in³/r)

Choose: WF8201116

Because: Best fit for left-hand drive applications needing high torque shaft coupling.

Compatibility: All models feature SAE ‘A’ 2-bolt flange mounting and G1″/G1/2″ BSPP straight thread ports, ensuring direct Vickers interchangeability and easy replacement in existing systems.
