The Worthington D1011 4x3x10 Frame 3 all iron pump stands as one of Thelco’s most in-demand models for fluid-handling operations. Today’s build features an empty box configuration and an impeller trimmed and balanced at 8.25 inches in diameter—tailored to meet performance requirements without sacrificing durability.

Built entirely from iron, this D1011 configuration offers a robust solution for operations that demand continuous, reliable service. It’s perfect for plants running clean or dirty fluids where heavy-duty, low-maintenance pumps make the difference in uptime.

The empty box design gives your team flexibility. Whether you’re installing a mechanical seal, packed box, or custom seal assembly, the D1011’s adaptable configuration simplifies integration. We trimmed and balanced the impeller to 8.25 inches to ensure an optimal operating point and stable system performance.

Engineered for Endurance

The D1011 construction offers a longer bearing span, added rigidity, and higher horsepower handling. When matched with Thelco’s exact-fit components—like replacement shafts, casings, and bearing frames—this pump becomes a critical asset in your facility.

We keep all the core parts for the D1011 in stock. So, if you’re planning an upgrade, overhaul, or new install, you don’t have to wait weeks to get what you need.
