Compatibility & Applications

Direct Replacement Information

This Fluidyne unit serves as a direct replacement for Vickers replacement pumps, specifically WF8201144 in systems requiring 26.6 cm³/r (1.62 in³/r) displacement and up to 2500 PSI continuous operation. Engineered for seamless interchangeability, it follows SAE J744 mounting standards and offers the same port and shaft configurations as the original Vickers model..

Mounting Pattern: SAE ‘A’ 2-bolt
Inlet Port: G1″ BSPP
Outlet Port: G1/2″ BSPP

Common Applications

Commonly used in marine applications, stationary power units, test stands, and other medium-duty hydraulic systems. For similar specs in different mounting or port configurations, see the V201P8P10D11R – FluiDyne V20 Pump applications.

Important: Verify pump model WF8201144 matches your existing Vickers unit before ordering. For technical assistance, contact (800) 823-4937.

Product Selection Guide

These FluiDyne V20 Series hydraulic vane pump models differ primarily in flow rate, displacement, shaft type, rotation, port sizes, and port positions. All are direct Vickers replacements, fully SAE J744 compliant, and rated to 2500 PSI, but subtle differences affect suitability for your specific hydraulic system.

?? 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
WF8201144 (Current)	8.4 GPM	2500 PSI	26.6 cm³/r (1.62 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)
WF8201179	9.4 GPM	2500 PSI	29.7 cm³/r (1.81 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201171	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 (5.7 GPM, 1.10 in³/r), WF8201138 the highest (13.5 GPM, 2.60 in³/r), while WF8201144 and WF8201171 are mid-range (8.4 GPM, 1.62 in³/r); WF8201179 slightly higher (9.4 GPM, 1.81 in³/r).

Selection Guide: Select WF8201139 for smaller actuators or precise control; WF8201138 for high-demand systems; WF8201144, WF8201171, or WF8201179 for medium flow needs.

Shaft Type and Extension

Difference: WF8201138 uses a 7/8″ threaded shaft; WF8201139 has a 9-tooth splined shaft; others use a 3/4″ straight shaft with key (extension lengths vary).

Selection Guide: Choose splined (WF8201139) for high-torque couplings, threaded (WF8201138) for legacy or threaded couplers, and straight keyed (others) for standard applications.

Rotation Direction

Difference: WF8201179 is left-hand (counter-clockwise); all others are right-hand (clockwise) rotation.

Selection Guide: Select WF8201179 for systems requiring reverse (left-hand) shaft rotation; otherwise, choose right-hand models.

Port Size and Position

Difference: WF8201171 uses a smaller 1″ NPT inlet versus 1-1/4″ NPT on others. Port positions: WF8201144, WF8201171, and WF8201179 have ports opposite (180°); WF8201138 and WF8201139 are inline (0°). WF8201179’s outlet is 1-1/16″-12 straight thread, others use 3/4″ NPT.

Selection Guide: Match inlet/outlet size to your plumbing; choose inline port models (WF8201138, WF8201139) for straight-through layouts, or 180° models for opposite-side connections.

Maximum Speed

Difference: WF8201139 allows up to 3000 RPM; WF8201138 up to 2400 RPM; others up to 2800 RPM.

Selection Guide: Use WF8201139 for high-speed drive applications; other models if your prime mover operates below 2800 RPM.

Quick Selection Guide

If you need: Highest flow and displacement (13+ GPM, 2.60 in³/r)

Choose: WF8201138

Because: It supplies the most volume for large hydraulic cylinders or fast cycle times. For more options, explore our full vane pumps selection.

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

Choose: WF8201139

Because: It handles up to 3000 RPM and is ideal for smaller systems or precise metering.

If you need: Standard 8 GPM, right-hand rotation, 1-1/4″ NPT inlet

Choose: WF8201144

Because: Best overall fit for typical mid-size systems mirroring Vickers V20-8.

If you need: 8 GPM, right-hand rotation, but have only 1″ NPT plumbing

Choose: WF8201171

Because: It fits tighter inlet connections while matching other core specs.

If you need: Medium flow, but require left-hand (CCW) rotation

Choose: WF8201179

Because: It’s the only left-hand rotation option for matching non-standard drive direction.

Compatibility: All models are 100% Vickers interchangeable with SAE ‘A’ 2-bolt mounting and G1″/G1/2″ BSPP straight thread ports, ensuring drop-in replacement and simplified installation.
