Stop losing $1,200 daily to unplanned hydraulic downtime. The V101S4R1A20R FluiDyne V10 delivers 4 GPM at 1200 RPM, proven in over 2,000 field installations. Typical payback is under 3 months for operators replacing Vickers pumps.

Technical Specifications

Flow Performance

At 4 GPM flow, the V101S4R1A20R hits the efficiency sweet spot for shop presses and small machine tools. This output matches Vickers V10 requirements exactly. Operators report saving up to 6 hours weekly on maintenance versus generic pumps.Performance stays consistent across 1200–3400 RPM speed range. After 1,500 hours, efficiency remains at 92%. Competing vane pumps drop to 82% or lower by this point.Installation takes 35 minutes with standard tools. The 2-bolt SAE “A” mounting pattern fits Vickers-equipped presses and compact tractors without adapters. Compatibility with anti-wear hydraulic oil prevents premature seal failure from fluid mismatch.

Efficiency & Durability

Maintains consistent efficiency throughout operational lifespan.

Features and Benefits

Direct Vickers Interchangeability: 100% drop-in fit slashes downtime. Operators report 65% faster replacements.
High Pressure Rating: 2,500 PSI max enables heavier loads. Machine uptime rises by 18% over lower-rated pumps.
Same-Day Shipping: In-stock units ship out within hours. Production lines stay moving with zero added lead-time.

Operational Information

Cold starts succeed at 10°F. Continuous duty is rated for 3,400 hours at 2,500 PSI. Handles 25% overload spikes without internal damage. Replace when output drops below 85% of rated flow.

Quality Assurance

Manufactured to the highest standards with rigorous quality control throughout the production process.

Product Selection Guide

These FluiDyne V10 (V101 Series) single vane pump models are direct, fully interchangeable replacements for Vickers replacement pumps, sharing core dimensions but differing primarily in displacement, flow rate, port position, shaft code, and pressure rating. Selecting the right model depends on matching flow/pressure needs, space constraints, and port orientation with your application.

?? 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

Displacement & Flow Rate

Difference: V101S4R1A20R delivers 0.80 in³/r (4 GPM at 1200 RPM); V101S6S1D20R, V101S6S27A20R, and V101S6S27C20R deliver 1.19 in³/r (6 GPM at 1200 RPM).

Selection Guide: Select V101S6S models for higher hydraulic flow needs (larger cylinders or faster cycle times); use V101S4R1A20R for compact systems or lower flow requirements.

Maximum Pressure Rating

Difference: V101S4R1A20R supports up to 2500 PSI; V101S6S models are rated to 2200 PSI.

Selection Guide: Choose V101S4R1A20R if your system operates near or above 2200 PSI for added margin.

Port Position

Difference: V101S4R1A20R: Ports opposite (180°); V101S6S1D20R: 90° clockwise from inlet; V101S6S27A20R: Ports opposite (180°); V101S6S27C20R: Ports inline (0°).

Selection Guide: Match port orientation to your plumbing layout—’opposite’ for straight-through lines, ’90°’ or ‘inline’ for tight or specific routing needs.

Shaft Code

Difference: V101S4R1A20R and V101S6S1D20R use standard 3/4″ keyed shafts; V101S6S27A20R and V101S6S27C20R use shaft code 27 (specifically keyed or splined).

Selection Guide: Use standard shaft for typical couplings; select shaft code 27 if your drive system requires a specific interface.

Maximum Speed

Difference: V101S4R1A20R: 3400 RPM; V101S6S models: 3000 RPM.

Selection Guide: If your drive motor runs above 3000 RPM, select V101S4R1A20R.

Quick Selection Guide

If you need: Lower flow, higher pressure, or higher speed (up to 3400 RPM)

Choose: V101S4R1A20R

Because: It provides up to 2500 PSI, handles higher speeds, and outputs 4 GPM—ideal for compact, higher-pressure systems.

If you need: Higher flow (6 GPM), moderate pressure (up to 2200 PSI)

Choose: Any V101S6S model

Because: All deliver 6 GPM at 1200 RPM and are suited for larger actuators or faster cycles at standard pressures.

If you need: Specific port orientation

Choose: V101S6S1D20R for 90° ports, V101S6S27A20R for opposite (180°), or V101S6S27C20R for inline (0°)

Because: These options align with unique plumbing layouts and space constraints.

If you need: Custom shaft interface

Choose: V101S6S27A20R or V101S6S27C20R

Because: Shaft code 27 supports specialized drives.

Compatibility: All models feature SAE ‘A’ 2-bolt mounting and G1″/G1/2″ BSPP straight thread ports, ensuring direct Vickers V10 interchangeability.
