Product Selection Guide

These Fluidyne V20 Series vane pumps offer the same core mounting and displacement, but differ primarily in flow rate, rotation direction, port and shaft configuration, and cover type. Choosing the right model depends on your required flow, desired rotation, available space for port orientation, and whether flow control is needed in your 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
WF820488 (Current)	9.4 GPM	2500 PSI	29.7 cm³/r (1.81 in³/r)	2-Bolt Flange (SAE “A” size)
WF820487	9.4 GPM	2500 PSI	29.7 cm³/r (1.81 in³/r)	2-Bolt Flange (SAE “A” size)
WF820481	9.4 GPM	2500 PSI	29.7 cm³/r (1.81 in³/r)	2-Bolt Flange (SAE “A” size)
WF820489	11.5 GPM	2500 PSI	36.3 cm³/r (2.22 in³/r)	2-Bolt Flange (SAE “A” size)
WF8201811	13.5 GPM	2500 PSI	42.6 cm³/r (2.60 in³/r)	2-Bolt Flange (SAE “A” size)

Key Differences

Flow Rate & Displacement

Difference: WF820488, WF820487, and WF820481 deliver 9.4 GPM (1.81 in³/r), WF820489 increases output to 11.5 GPM (2.22 in³/r), and WF8201811 provides the highest at 13.5 GPM (2.60 in³/r).

Selection Guide: Select WF8201811 for larger actuators or faster cycle times; choose WF820488/WF820487/WF820481 for standard medium-duty needs.

Rotation Direction

Difference: WF820488, WF820487, and WF820489 are left-hand (counter-clockwise); WF820481 and WF8201811 are right-hand (clockwise).

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

Port Position

Difference: WF820488, WF820487, and WF8201811 have inline (0°) ports; WF820481 has ports 90° clockwise, WF820489 has ports 90° counter-clockwise.

Selection Guide: Use inline ports for direct, straight-line plumbing; choose 90° ports for installations with space constraints or specific routing needs.

Cover Type

Difference: WF820489 features a Flow Control Cover with built-in relief (2000 PSI) and flow control (11 GPM); others have Standard Covers.

Selection Guide: Choose WF820489 for circuits requiring integral flow control and pressure relief—ideal for systems needing precise flow regulation.

Shaft Configuration

Difference: WF820488 and WF820489 have 11-tooth splined shafts (1.25″ extension), WF820487 and most others use 3/4″ straight keyed shafts (1.75″-2.66″ extension), and others specify special shaft codes.

Selection Guide: Use splined shafts for high-torque, heavy-duty drives; straight keyed shafts suit most standard couplings.

Maximum Pressure & Speed

Difference: All models except WF8201811 are rated to 2500 PSI; WF8201811 specifies 2200 PSI in description (but 2500 PSI in specs)—confirm required system pressure. Max speed varies: up to 2800 RPM for standard models, 2400-2500 RPM for high-flow or flow control versions.

Selection Guide: For systems with intermittent high pressure, any model except possibly WF8201811 is suitable; for continuous high flow, verify pressure and speed requirements match your system.

Quick Selection Guide

If you need: Standard 9.4 GPM flow, left-hand rotation, inline ports, and a splined shaft

Choose: WF820488

Because: Best for standard Vickers V20 replacements where a splined shaft is preferred for torque transmission.

If you need: Standard 9.4 GPM flow, left-hand rotation, inline ports, and a straight keyed shaft

Choose: WF820487

Because: Select when a straight key shaft is required for your coupling style.

If you need: Standard 9.4 GPM flow, right-hand rotation, 90° port orientation

Choose: WF820481

Because: Ideal for systems needing right-hand rotation and 90° port orientation for tight plumbing layouts.

If you need: Higher flow (11.5 GPM), left-hand rotation, integrated flow control & relief

Choose: WF820489

Because: Provides built-in flow regulation and relief valve for precise system control.

If you need: Maximum flow rate (13.5 GPM), right-hand rotation, inline ports

Choose: WF8201811

Because: Best for high-output systems needing increased speed or larger cylinder actuation.

Compatibility: All models are direct Vickers V20 replacements, fully interchangeable in mounting (SAE ‘A’ 2-bolt flange) and port sizing (G1″/G1/2″ BSPP straight threads), making upgrades or replacements seamless.
