Overview

The $1,200 problem of unplanned downtime? Solved. V201P11P18B11R’s 100% Vickers interchangeability delivers fast swaps and proven uptime. Most operators report 2-month payback after installation.

Technical Specifications

Flow Performance

At 11 GPM, the V201P11P18B11R hits the efficiency sweet spot for mid-size loaders and presses. This output matches Vickers V20 demands exactly. Operators save 3 hours weekly on maintenance compared to retrofits.

Efficiency & Durability

Performance stays consistent from 1200 to 2800 RPM. After 2,000 hours, efficiency remains at 95%. Comparable gear pumps drop to 85% by then, costing more in energy and downtime.

Installation

Installation takes 35 minutes using standard tools. The 2-bolt SAE “A” flange fits Caterpillar, John Deere, and Komatsu units without adapters. Broad fluid compatibility prevents seal failure from oil changes.

Features and Benefits

Mounting Design: 2-bolt SAE “A” flange cuts install time to 35 minutes—47% faster than typical Vickers swaps.
Pressure: 2,500 PSI max rating handles 15% higher load surges, reducing risk of line bursts.
Port Layout: 90° outlet orientation fits tight engine bays, improving hose life by 22% on average.

Operational Information

Cold starts succeed at 10°F. Continuous operation rated for 2,000 hours at 2,500 PSI. Handles 10% 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.
