Compatibility & Applications

Direct Replacement Information

This Fluidyne unit serves as a direct replacement for Vickers V10F1P4P12A4E20L in systems requiring 13.1 cm³/r (0.80 in³/r) displacement and up to 2500 PSI max pressure..

• Mounting Pattern: SAE ‘A’ 2-bolt
• Inlet Port: G1″ BSPP
• Outlet Port: G1/2″ BSPP

Common Applications

Commonly used in marine applications, stationary power units, test stands. Explore V101S6S1D20R – FluiDyne V10 Pump for smaller displacement needs in similar environments. For other high-performance options in this displacement, see V10F1P4P11A2E20R – FluiDyne V10 Pump applications.

• marine applications
• stationary power units
• test stands

Important: Verify pump model V10F1P4P12A4E20L matches your existing Vickers unit before ordering. For technical assistance, contact (800) 823-4937.

Product Selection Guide

These FluiDyne V10 Series models are all direct Vickers V10 replacements, sharing the same displacement (0.80 in³/r), continuous pressure (2500 PSI), flow rate (4.2 GPM at 1200 RPM), and SAE ‘A’ 2-bolt mounting. The key differences lie in shaft type, flow control setting, relief valve setting, and rotation direction—each impacting installation and suitability for specific hydraulic circuits or machine 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

Rotation Direction

Difference: V10F1P4P12A4E20L and V10F1P4P11A4D20L are Left-Hand (Counter-Clockwise); V10F1P4P11A2E20R, V10F1P4P11A3D20R, and V10F1P4P11A4D20R are Right-Hand (Clockwise)

Selection Guide: Choose Left-Hand models for systems requiring counter-clockwise shaft input; choose Right-Hand models for clockwise-driven applications.

Flow Control Setting

Difference: V10F1P4P11A2E20R: 2 GPM; V10F1P4P11A3D20R: 3 GPM; V10F1P4P12A4E20L, V10F1P4P11A4D20L, V10F1P4P11A4D20R: 4 GPM

Selection Guide: Pick lower flow control (2 or 3 GPM) for precise or lower-demand circuits; select 4 GPM models for higher flow requirements or standard V10 applications.

Relief Valve Setting

Difference: V10F1P4P12A4E20L and V10F1P4P11A2E20R: 1250 PSI; V10F1P4P11A3D20R, V10F1P4P11A4D20L, V10F1P4P11A4D20R: 1000 PSI

Selection Guide: Opt for 1250 PSI relief for circuits needing higher overpressure tolerance; use 1000 PSI relief for lower system protection thresholds or to match downstream components.

Shaft Type

Difference: V10F1P4P12A4E20L: 13-Tooth Splined Shaft; other models: 9-Tooth Splined Shaft

Selection Guide: Select 13-Tooth Splined Shaft for higher torque transmission or specific coupling compatibility; use 9-Tooth for standard V10 installations.

Quick Selection Guide

If you need: Maximum flow (4 GPM) with higher relief setting and left-hand rotation

Choose: V10F1P4P12A4E20L

Because: Provides 4 GPM at 1200 RPM, 1250 PSI relief, 13-tooth splined shaft, and left-hand rotation for demanding or high-torque counter-clockwise drives.

If you need: Right-hand rotation with standard flow and lower relief setting

Choose: V10F1P4P11A4D20R

Because: Offers 4 GPM at 1200 RPM, 1000 PSI relief, 9-tooth splined shaft, and clockwise rotation—suitable for typical V10 replacements.

If you need: Precise low-flow control in a clockwise application

Choose: V10F1P4P11A2E20R (2 GPM) or V10F1P4P11A3D20R (3 GPM)

Because: Ideal for applications requiring reduced flow at the pump outlet, preventing excess heat or over-speeding actuators.

If you need: Standard V10 features with left-hand rotation and lower relief

Choose: V10F1P4P11A4D20L

Because: Provides 4 GPM at 1200 RPM, 1000 PSI relief, for counter-clockwise drive systems where lower overpressure protection is desired.

Compatibility: All models are 100% interchangeable with Vickers V10 pumps, using SAE ‘A’ 2-bolt mounting (see V10F1P4P11A2E20R applications for a right-hand rotation alternative) and G1″/G1/2″ BSPP ports for straightforward replacement in compact hydraulic applications.
