Fluidyne V101 V101B5B11D20R - 5 GPM 1.00 in³/r 2500 PSI SAE 'A' 2-Bolt Flange, 9-Tooth Splined Shaft - Direct Vickers V10 Replacement

Stop losing $1,250 daily to hydraulic downtime. The V101B5B11D20R delivers 5 GPM at 1200 RPM proven in 2,100 installations. 3-month ROI typical for operators switching from Vickers V10 failures.

Technical Specifications

Flow Performance

At 5 GPM, the V101B5B11D20R hits the efficiency sweet spot for compact loaders and balers. This matches Vickers V10 system requirements exactly. Operators save 4 hours weekly versus rebuilding worn pumps.

Efficiency & Durability

Performance stays consistent across 1,200-3,200 RPM. After 2,000 hours, efficiency remains at 91%. Comparable remanufactured pumps drop to 76% by then.

Installation

Installation takes 35 minutes using standard tools. The 2-bolt SAE “A” flange pattern fits John Deere 310, Case 580, and Bobcat 773 without adapters. ISO 32-68 oil compatibility prevents seal degradation over time.

Features and Benefits

Direct Fit: 100% Vickers V10 model interchangeability eliminates costly downtime. Equipment operators report 94% faster turnaround.
Pressure Handling: 2,500 PSI max rating prevents blown seals in high-shock cycles. Fleet managers see 37% fewer warranty calls.
Shipping Speed: Same-day shipping on in-stock units slashes lead time from 8 days to 1. Maintenance teams reduce backup inventory by 32%.

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 five FluiDyne V101 models are part of our vane pumps portfolio and are direct Vickers V10 replacements with identical displacement (16.4 cm³/r or 1.00 in³/r), pressure rating (2500 PSI), and standard SAE ‘A’ 2-bolt mounting. The critical differences are in shaft type, port orientation, and pump rotation direction—features that directly impact installation compatibility and drivetrain matching in your equipment.

Key Differences

Shaft Type

Difference: V101B5B11D20R is equipped with a 9-tooth splined shaft for higher torque, while V101B5B1A20R, V101B5B1C20R, and V101B5B1D20R feature a 3/4″ straight keyed shaft (1.75″ extension), and V101B5B41B20L uses shaft code 41 (details available on request).

Selection Guide: Select the 9-tooth splined shaft (V101B5B11D20R) for high-torque or splined-coupling drivetrains. Use straight keyed shafts when your equipment accepts keyed couplings. Confirm shaft code 41 details for V101B5B41B20L if unsure.

Port Position

Difference: V101B5B1A20R has ports 180° apart (opposite), V101B5B1C20R has ports inline (0°), V101B5B11D20R and V101B5B1D20R have ports 90° clockwise from inlet, and V101B5B41B20L has ports 90° counter-clockwise from inlet.

Selection Guide: Choose port position based on hose routing needs: inline (0°) and opposite (180°) for straightforward connections, 90° options for installations with space restrictions or to avoid hose interference.

Rotation Direction

Difference: All models except V101B5B41B20L rotate right-hand (clockwise). V101B5B41B20L rotates left-hand (counter-clockwise).

Selection Guide: Match pump rotation to your drive source: right-hand (R) for standard clockwise drives, left-hand (L) for applications requiring counter-clockwise operation.

Quick Selection Guide

If you need: A high-torque shaft or splined coupling compatibility

Choose: V101B5B11D20R

Because: The 9-tooth splined shaft is ideal for high-torque, spline-coupled drives, common in compact tractors and construction equipment.

If you need: Straight keyed shaft with 90° port orientation

Choose: V101B5B1D20R

Because: This model combines a standard keyed shaft with ports 90° from inlet—useful for common right-hand installations with side-facing hoses.

If you need: Inline port connections for direct, straight-through plumbing

Choose: V101B5B1C20R

Because: Ports are inline (0°), simplifying hose routing in compact, linear layouts.

If you need: Opposite-facing ports for applications requiring hoses on each side

Choose: V101B5B1A20R

Because: Ports are 180° apart, ideal for mounting between two hose runs.

If you need: Counter-clockwise (left-hand) pump rotation

Choose: V101B5B41B20L

Because: This is the only left-hand rotation model in this group, required for certain engine or PTO-driven systems.

Compatibility: All listed models are 100% Vickers V10 interchangeable, feature SAE ‘A’ mounting, and share G1″ BSPP inlet and G1/2″ BSPP outlet ports—ensuring direct fit and hassle-free replacement. For similar displacement but different port or shaft combinations, see our V101B2B1C20R model.
