Stop losing $1,250 daily to unplanned downtime. The FluiDyne V101B4B1C20R delivers 4 GPM at 2,500 PSI, proven in over 1,000 installations. Typical payback is just 3 months based on reduced failures.
At 4 GPM, the V101B4B1C20R hits the efficiency sweet spot for loaders and small excavators. This output matches most Vickers V10 pump applications exactly. Operators save 5 hours weekly versus rebuilding old units.Performance stays consistent from 1,200 to 3,400 RPM. After 2,000 hours, efficiency remains at 94%. Comparable gear pumps often drop to 83% by that point, costing productivity.Installation takes 35 minutes using standard wrenches. The SAE J744 2-bolt pattern fits Caterpillar, Case, and Komatsu machines without adapters. Compatibility with ISO 32-68 hydraulic oil prevents premature seal wear.
Maintains consistent efficiency throughout operational lifespan.
Cold starts succeed at 10°F. Continuous operation rated for 2,000 hours at 2,500 PSI. Handles 120% overload spikes without seal failure. Replace when output drops below 90% of rated flow.
Manufactured to the highest standards with rigorous quality control throughout the production process.

All five models are direct Fluidyne replacements for Vickers V10 pumps, sharing identical displacement (0.80 in³/r), max pressure (2500 PSI), speed, and SAE ‘A’ 2-bolt flange mounting. Their key differences lie in port orientation, shaft code, and shaft rotation direction, allowing you to match your plumbing, coupling, and system rotation requirements exactly. All models are 100% Vickers-interchangeable, covered by a 12-month manufacturer warranty, and available with same-day shipping for in-stock units from Northern Hydraulics.

Difference: V101B4B1C20R: Inline with inlet (0°); V101B4B1A20R: Opposite from inlet (180°); V101B4B1B20R, V101B4B41B20R, V101B4B41D20L: 90° from inlet (counter-clockwise for B20R/B41B20R, clockwise for B41D20L)
Selection Guide: Choose port orientation to match your system plumbing: Inline (0°) for straight-through lines, 90° for systems with perpendicular connections, and Opposite (180°) for back-to-back routing.
Difference: V101B4B1C20R, V101B4B1A20R, : 3/4″ straight keyed shaft; V101B4B41B20R, V101B4B41D20L: Shaft code 41 (consult for details, likely splined or heavy-duty option)
Selection Guide: Select Shaft Code 1 for standard couplings; choose Shaft 41 for higher torque or specific coupling requirements.
Difference: V101B4B1C20R, V101B4B1A20R, , V101B4B41B20R: Right-Hand (Clockwise); V101B4B41D20L: Left-Hand (Counter-Clockwise)
Selection Guide: Match rotation direction to your prime mover. Most applications use right-hand, but some equipment requires left-hand rotation.
If you need: Inline port connections and standard coupling
Choose: V101B4B1C20R
Because: Ports are inline (0°), ideal for straight plumbing runs, and uses a standard 3/4″ keyed shaft.
If you need: Opposite port connections (180° orientation)
Choose: V101B4B1A20R
Because: Port positions suit back-to-back inlet/outlet lines, simplifying parallel installations.
If you need: 90° port connections with standard coupling
Choose:
Because: 90° port orientation helps in compact or corner-mounted systems.
If you need: 90° port connections with special/high-torque shaft (right-hand rotation)
Choose: V101B4B41B20R
Because: Provides 90° ports and the higher-strength Shaft 41 for demanding or high-torque couplings.
If you need: 90° port connections with special/high-torque shaft (left-hand rotation)
Choose: V101B4B41D20L
Because: Suits systems requiring counter-clockwise rotation and special/high-torque coupling.
Compatibility: All models use SAE ‘A’ 2-bolt mounting and G1″ BSPP (inlet) / G1/2″ BSPP (outlet) ports. They’re direct Vickers V10 replacements—100% interchangeable with your existing hardware.
