Fluidyne V10 V101B4B1A20R - 4 GPM (0.80 in³/r), 2500 PSI, SAE A 2-Bolt Flange, 3/4" Keyed Shaft - Direct Vickers Replacement Pump

Stop losing $1,250 daily to unplanned downtime. The V101B4B1A20R delivers 4 GPM at 1200 RPM, proven in over 3,400 field installations. Typical payback is under 2 months—with direct Vickers compatibility and same-day shipping from Northern Hydraulics.

Technical Specifications

Flow Performance

At 4 GPM flow, the V101B4B1A20R hits the efficiency sweet spot for loader and press circuits. This matches Vickers V10 system requirements exactly. Operators save 3.5 hours weekly versus using generic fit pumps.

Efficiency & Durability

Performance stays consistent across 1200–3400 RPM. After 2,000 hours of operation, efficiency remains at 93%. Comparable aftermarket vane pumps drop to 81% by that time, requiring early replacement.

Installation

Installation takes 35 minutes using standard hand tools. The 2-bolt SAE “A” flange pattern fits Vickers, John Deere, and Komatsu equipment without adapters. ISO 32–68 hydraulic oil compatibility prevents premature seal degradation and extends service intervals.

Features and Benefits

Direct Vickers Interchange: 100% model code match eliminates retrofit costs. Fleet managers report 28% fewer installation errors.
Pressure Handling: 2,500 PSI max rating prevents seal leaks during heavy duty use. Operators see 19% less downtime.
Same-Day Shipping: Orders placed by 3 PM MST ship out the same day. Maintenance teams reduce waiting time by 58%.

Operational Information

Cold starts succeed at 0°F. Continuous operation rated for 2,000 hours at 2,500 PSI. Handles 15% overload spikes without damage. Replace when efficiency drops below 85%.

Quality Assurance

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

Product Selection Guide

All listed models are FluiDyne V10 Series single vane pumps directly interchangeable with Vickers V10, sharing identical displacement (0.80 in³/r), pressure (2500 PSI), mounting (SAE ‘A’), and port sizes. Explore more options in our hydraulic pumps product family. The key differences are port orientation, shaft configuration, and rotation direction, which impact installation flexibility and equipment drive requirements.

Key Differences

Port Orientation

Difference: Port positions vary: V101B4B1A20R (180° opposite), V101B4B1B20R (90° counter-clockwise), V101B4B1C20R (inline/0°), V101B4B41B20R (90° counter-clockwise), V101B4B41D20L (90° clockwise).

Selection Guide: Select port orientation that best matches your hydraulic hose routing—inline (0°) for straight plumbing, 90° or 180° for space or clearance constraints. For maintenance or cartridge replacements, see our vane pump cartridge kits.

Shaft Configuration

Difference: Most models use a 3/4″ straight shaft with key; models with shaft code 41 (V101B4B41B20R, V101B4B41D20L) may have a different shaft design.

Selection Guide: Choose the shaft option that matches your drive connection. For more technical details, visit our vane pumps technical resource page. Verify shaft code 41 with technical support for compatibility with couplings or high-torque applications.

Rotation Direction

Difference: Models V101B4B1A20R, V101B4B1B20R, V101B4B1C20R, and V101B4B41B20R are right-hand (clockwise); V101B4B41D20L is left-hand (counter-clockwise).

Selection Guide: Choose right-hand for standard engine or motor rotation; left-hand if your drive runs counter-clockwise.

Quick Selection Guide

If you need: Ports directly opposite each other (180°), right-hand rotation

Choose: V101B4B1A20R

Because: Ideal for equipment where hoses or fittings need to be on opposite sides for straight-line installation.

If you need: Ports at 90° counter-clockwise from inlet, right-hand rotation

Choose: V101B4B1B20R or V101B4B41B20R

Because: Best for installations with limited access or where hoses must turn 90° for routing.

If you need: Ports inline with each other (0°), right-hand rotation

Choose: V101B4B1C20R

Because: Simplifies plumbing when both ports are aligned for direct connection.

If you need: Ports at 90° clockwise from inlet, left-hand rotation

Choose: V101B4B41D20L

Because: Suited for equipment requiring counter-clockwise pump rotation.

Compatibility: All models are 100% interchangeable with Vickers V10, using SAE ‘A’ 2-bolt flange mounting and G1″/G1/2″ BSPP ports. See all Vickers replacement pumps for more compatibility options. Direct-fit for Vickers replacements.
