Product Selection Guide

These single stage vane pumps in the Fluidyne V20 Series are all direct Vickers replacements with SAE ‘A’ 2-bolt mounting, but differ primarily in flow rate, displacement, shaft type, rotation direction, port positions, and port thread styles. Choosing the right model depends on your required flow, system rotation, space constraints for port orientation, and shaft/coupling compatibility.

?? 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
WF8203004 (Current)	9.4 GPM	2500 PSI	29.7 cm³/r (1.81 in³/r)	2-Bolt Flange (SAE “A” size)
WF8203060	9.4 GPM	2500 PSI	29.7 cm³/r (1.81 in³/r)	2-Bolt Flange (SAE “A” size)
WF8203031	5.7 GPM	2500 PSI	18.0 cm³/r (1.10 in³/r)	2-Bolt Flange (SAE “A” size)
WF8203009	6.2 GPM	2500 PSI	19.5 cm³/r (1.19 in³/r)	2-Bolt Flange (SAE “A” size)
WF8203013	10.4 GPM	2500 PSI	32.8 cm³/r (2.00 in³/r)	2-Bolt Flange (SAE “A” size)

Key Differences

Flow Rate & Displacement

Difference: WF8203013 offers the highest flow (10.4 GPM, 32.8 cm³/r, see V201P13P39C11R – FluiDyne V20 Pump), WF8203004 and WF8203060 are mid-range (9.4 GPM, 29.7 cm³/r), while WF8203009 (6.2 GPM, 19.5 cm³/r) and WF8203031 (5.7 GPM, 18.0 cm³/r) serve lower-flow needs.

Selection Guide: Select higher GPM/displacement models for larger actuators or faster cycle times; choose lower ones for smaller loads or precise control.

Shaft Type

Difference: WF8203060 uses an 11-tooth splined shaft (for higher torque and coupling flexibility); the others use a 3/4″ straight keyed shaft.

Selection Guide: Choose splined shaft if your system demands higher torque transmission or you use splined couplings; straight keyed shafts fit most standard couplings.

Rotation Direction

Difference: WF8203004, WF8203060, and WF8203009 are right-hand (clockwise); WF8203013 and WF8203031 are left-hand (counter-clockwise).

Selection Guide: Match pump rotation to your drive motor and existing plumbing; incorrect rotation can damage the pump.

Port Position

Difference: WF8203004 has ports at 90° counter-clockwise from inlet; WF8203060 at 180° (opposite from inlet); the rest are inline (0°).

Selection Guide: Select port orientation to simplify hose routing and fit within your installation space.

Port Thread Style

Difference: WF8203004 and WF8203060 have 1-1/4″ NPT inlets and 1-1/16″ or 3/4″ NPT outlets; WF8203013 uses straight thread inlets/outlets; all provide G1″/G1/2″ BSPP straight thread ports.

Selection Guide: Choose NPT for standard pipe fittings; straight thread for leak-resistant O-ring connections or if matching existing plumbing.

Maximum Speed

Difference: WF8203009 can run up to 3400 RPM (highest); WF8203031 up to 3000 RPM; WF8203004 and WF8203060 up to 2800 RPM; WF8203013 up to 2500 RPM.

Selection Guide: For high-speed drives, select a model with suitable max RPM. Lower max RPM may limit pump output at faster motor speeds.

Quick Selection Guide

If you need: Highest flow rate and largest displacement

Choose: WF8203013

Because: It delivers 10.4 GPM (32.8 cm³/r) and is ideal for large actuators or rapid operations, with left-hand rotation.

If you need: Standard flow with right-hand rotation and keyed shaft

Choose: WF8203004

Because: It offers 9.4 GPM at 1200 RPM, right-hand rotation, and a straightforward 3/4″ keyed shaft for general applications.

If you need: Standard flow with splined shaft for higher torque coupling

Choose: WF8203060

Because: It matches WF8203004 in flow and displacement, but offers an 11-tooth splined shaft for applications requiring robust torque transfer.

If you need: Lower flow with right-hand rotation

Choose: WF8203009

Because: It delivers 6.2 GPM (1.19 in³/r), right-hand rotation, and higher max RPM (3400), making it suitable for smaller actuators or systems with high-speed drives. For similar displacement and port options, see V201P8P10D11R – FluiDyne V20 Pump.

If you need: Lower flow with left-hand rotation

Choose: WF8203031

Because: It provides 5.7 GPM (1.10 in³/r), left-hand rotation, and higher speed capability (3000 RPM), fitting compact or reverse-rotation systems. For applications with similar requirements, review V201P13P3A11R – FluiDyne V20 Pump.

Compatibility: All models are 100% Vickers interchangeable, share SAE ‘A’ 2-bolt mounting, and G1″/G1/2″ BSPP straight thread ports for easy retrofit or replacement within existing systems. Explore our full range of Vickers replacement pumps for additional compatibility. Pressure ratings are 2500 PSI across the board.
