Thelco Pump of the Day: Worthington 3LLR-11 – Built for Flow, Backed by Stock

The Worthington 3LLR-11 standard fitted pump with a 9.80” trimmed and balanced impeller delivers reliable, high-capacity performance for demanding industrial operations. This double-suction horizontal split case pump is engineered for high-volume fluid movement while maintaining long-term mechanical stability.

High-Efficiency Fluid Handling

With its split-case design, the 3LLR-11 simplifies maintenance and minimizes wear. The double-suction impeller configuration evenly balances axial forces, reducing bearing stress and extending pump life. At Thelco, we precision trim and balance impellers like this one to 9.80 inches, enhancing efficiency and reducing vibration.

Whether installed in power plants, water treatment facilities, or heavy industrial systems, this pump moves fluid with consistency and confidence. Its iron construction ensures long-term durability in harsh conditions, while its design simplifies serviceability.
