Product Selection Guide

These FluiDyne V20 Series vane pumps are all direct Vickers replacements, sharing common mounting, port sizes, and pressure ratings. The key differences between models are flow rate, displacement, shaft type, rotation, port orientation, and maximum speed. These factors determine suitability for various hydraulic systems, directions of drive, and installation requirements.

?? 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: WF8201902 provides 6.2 GPM (1.19 in³/rev), WF8201912, WF8201958, and WF8201949 provide 8.4 GPM (1.62 in³/rev), and WF8201950 delivers 13.5 GPM (2.60 in³/rev), all at 1200 RPM. For an alternative 26.6 cm³/r model with a different cover, see V201P8P10D11R – FluiDyne V20 Pump.

Selection Guide: Select WF8201950 for higher-demand systems needing up to 13.5 GPM; choose WF8201902 for lower flow requirements or when precise, low-volume delivery is critical.

Rotation Direction

Difference: WF8201902 and WF8201949 are left-hand (counter-clockwise); others are right-hand (clockwise).

Selection Guide: Choose left-hand rotation models for equipment with counter-clockwise drive; right-hand for standard clockwise drive shafts.

Port Position

Difference: WF8201912 has 90° counter-clockwise port orientation; WF8201950 and WF8201902 have ports opposite (180°); WF8201958 and WF8201949 have inline (0°) ports.

Selection Guide: Use 90° ports (WF8201912) to simplify plumbing in tight or corner installations; use inline or opposite ports for straightforward, linear connections.

Shaft Type

Difference: WF8201912, WF8201950, and WF8201958 use splined shafts; WF8201902 and WF8201949 use straight keyed shafts; WF8201949 has a special shaft configuration.

Selection Guide: Select splined shafts for high-torque or precision coupling; straight keyed shafts for standard, cost-effective setups. For additional series options, review our V201P13P39C11R – FluiDyne V20 Pump.

Maximum Speed

Difference: WF8201902 supports up to 3400 RPM; others range from 2400 to 2800 RPM.

Selection Guide: Pick WF8201902 for high-speed systems or variable-speed drives.

Quick Selection Guide

If you need: The highest flow at 1200 RPM (up to 13.5 GPM)

Choose: WF8201950

Because: It delivers the highest displacement and flow, ideal for large cylinders or rapid actuator cycles.

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

Choose: WF8201902

Because: Its 6.2 GPM flow and 3400 RPM max speed suit smaller systems or applications where pump speed varies.

If you need: Standard 8 GPM flow with clockwise rotation

Choose: WF8201912 or WF8201958

Because: Both offer 8.4 GPM at 1200 RPM with right-hand rotation; select based on port orientation and shaft type.

If you need: Standard 8 GPM flow with counter-clockwise rotation

Choose: WF8201949

Because: It provides 8.4 GPM at 1200 RPM with left-hand rotation for non-standard drives.

Compatibility: All models feature SAE ‘A’ 2-bolt flange mounts and G1″/G1/2″ BSPP straight thread ports, ensuring direct Vickers interchangeability and easy installation.
