Product Selection Guide

The FluiDyne V20 Series models compared here differ mainly in flow rate, displacement, shaft type, port position, and rotation direction. All are direct replacements for Vickers pumps, feature SAE ‘A’ 2-bolt flange mounting, and are rated up to 2500 PSI. Selection depends on your system’s required flow, speed, shaft and porting preferences, and direction of rotation.

?? 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.

Key Differences

Flow Rate & Displacement

Difference: V201P13P39C11R offers the lowest flow (6.2 GPM, 1.19 in³/r); WF8201405 has the highest (12.5 GPM, 2.41 in³/r); others (WF820149, V201P13P3A11R, WF8201424) are mid-range (7–8.4 GPM, 1.39–1.62 in³/r).

Selection Guide: Choose WF8201405 for higher flow applications; for smaller actuators or reduced flow needs; and WF8201424 for moderate flow requirements.

Shaft Type

Difference: WF8201405 and WF8201424 use an 11-tooth splined shaft; , WF820149, and use a 3/4″ straight keyed shaft.

Selection Guide: Select splined shafts (WF8201405, WF8201424) for high-torque, heavy-duty coupling; use straight keyed shafts for standard installations.

Port Position

Difference: WF8201405 and WF820149: inline (0°); : 90° counter-clockwise from inlet; : inline (0°); WF8201424: opposite from inlet (180°).

Selection Guide: Choose inline ports for straightforward hose routing; 90° or 180° ports for tight or complex installations.

Rotation Direction

Difference: WF8201405 and WF8201424 are left-hand (counter-clockwise); , WF820149, are right-hand (clockwise).

Selection Guide: Match pump rotation to your drive motor direction—select left-hand for CCW systems, right-hand for CW systems.

Max Speed

Difference: allows the highest speed (3400 RPM); others range from 2400–3000 RPM.

Selection Guide: is best if high-speed operation is required.

Port Thread Types

Difference: WF8201405: 1-5/8″-12 (inlet), 1-1/16″-12 (outlet); : 1-1/4″ NPT (inlet), 1-1/16″-12 (outlet); WF820149, , WF8201424: 1-1/4″ NPT (inlet), 3/4″ NPT (outlet). All have G1″/G1/2″ BSPP straight thread options.

Selection Guide: Confirm port threads match your system; NPT for standard pipe, straight threads for high-pressure or leak-free connections.

Quick Selection Guide

If you need: Highest flow (12.5 GPM) and displacement (2.41 in³/r)

Choose: WF8201405

Because: Best for large actuators or systems needing rapid movement; also features splined shaft and inline ports.

If you need: Lowest flow (6.2 GPM) and highest speed capability (3400 RPM)

Choose:

Because: Ideal for compact systems, smaller cylinders, or high-speed drives.

If you need: Moderate flow with right-hand rotation

Choose: WF820149 or

Because: Offer 7–8.4 GPM with right-hand rotation and different port positions for flexible installation.

If you need: Moderate flow with left-hand rotation

Choose: WF8201424

Because: Provides 8.4 GPM, left-hand rotation, and splined shaft for high-torque applications.

If you need: High-torque shaft connection

Choose: WF8201405 or WF8201424

Because: Both feature 11-tooth splined shafts suitable for demanding drives.
