Product Selection Guide

These FluiDyne V20 Series hydraulic vane pumps differ primarily in flow rate, displacement, shaft/port configurations, and rotation direction. All models are direct Vickers replacements, share SAE ‘A’ 2-bolt mounting, and support up to 2500 PSI, making them fully interchangeable for most applications. For even greater flexibility, review our single stage vane pumps catalog. Key selection considerations include the required flow (GPM), displacement, port orientation, shaft type, and 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.

Model Number	Flow Rate	Max Pressure	Displacement	Mounting
WF8201874 (Current)	11.5 GPM	2500 PSI	36.3 cm³/r (2.22 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201811 (V201P13P39C11R – FluiDyne V20 Pump)	13.5 GPM	2500 PSI	42.6 cm³/r (2.60 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201824	6.2 GPM	2500 PSI	19.5 cm³/r (1.19 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201867	6.2 GPM	2500 PSI	19.5 cm³/r (1.19 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201889	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: WF8201811 delivers the highest flow at 13.5 GPM (2.60 in³/rev), WF8201874 offers 11.5 GPM (2.22 in³/rev), WF8201889 produces 8.4 GPM (1.62 in³/rev), while WF8201824 and WF8201867 both offer 6.2 GPM (1.19 in³/rev).

Selection Guide: Select higher flow/displacement models (WF8201811, WF8201874) for faster actuator speeds or larger systems; choose lower flow models (WF8201824, WF8201867, WF8201889) for smaller or more precise systems.

Rotation Direction

Difference: WF8201824 rotates left-hand (counter-clockwise), while all others rotate right-hand (clockwise).

Selection Guide: Match pump rotation to your system’s drive requirements; choose WF8201824 only if left-hand rotation is needed.

Port Orientation

Difference: WF8201874 has ports opposite each other (180°), WF8201889 has outlet at 90° counter-clockwise from inlet, others (WF8201811, WF8201824, WF8201867) have inline ports (0°).

Selection Guide: Use inline ports for straight-line plumbing; 90° or 180° for compact or specific routing needs.

Shaft Configuration

Difference: WF8201824 and WF8201889 are listed with splined shafts in their descriptions, but all models in the shared specs table default to 3/4″ straight keyed shaft.

Selection Guide: For high-torque or non-slip applications, verify availability of splined shaft options; otherwise, standard straight key works for most uses.

Maximum Speed

Difference: WF8201824 and WF8201867 support up to 3400 RPM (highest); WF8201889 up to 2800 RPM; WF8201874 and WF8201811 up to 2500 and 2400 RPM respectively.

Selection Guide: Choose higher speed models if your system operates at elevated RPMs.

Quick Selection Guide

If you need: Highest flow (13.5 GPM) for large cylinders or rapid cycles

Choose: WF8201811

Because: Delivers the maximum volume per minute—ideal for larger or faster hydraulic circuits.

If you need: Mid-range flow (11.5 GPM), right-hand rotation, and 180° port positioning

Choose: WF8201874

Because: Balances good flow with a unique port arrangement for flexible installation.

If you need: Compact system, lower flow (6.2 GPM) with left-hand rotation

Choose: WF8201824

Because: Only model in this group with counter-clockwise rotation.

If you need: Lower flow (6.2 GPM), right-hand rotation, and inline porting

Choose: WF8201867

Because: Best fit for small systems requiring standard port orientation.

If you need: Moderate flow (8.4 GPM), right-hand rotation, and 90° port offset

Choose: WF8201889

Because: Provides a compromise between flow and port flexibility for tight or cornered installations.

Compatibility: All models feature SAE ‘A’ 2-bolt flange mounting and G1″/G1/2″ BSPP straight thread ports, ensuring direct Vickers replacement and full interchangeability. For more options, explore our Vickers replacement pumps selection.
