Thelco Pump of the Day: Worthington D1011 4x3x10 Frame 3 All Iron Build

Today’s featured pump is a robust Worthington D1011 4x3x10 Frame 3 in all iron construction. This unit comes equipped with an impeller trimmed and balanced to 8.25 inches in diameter, making it ready for high-efficiency service right out of the box. Designed for performance in demanding environments, this pump is a go-to solution when you need reliability that endures.

Precision in Every Build

We trimmed and balanced the impeller precisely to 8.25” to ensure maximum efficiency within a defined performance curve. The all-iron build provides strength and durability while simplifying maintenance. It’s engineered to meet the needs of industrial users who demand consistent results.

Why the D1011 4x3x10?

This model balances power and size perfectly for mid-range flow and head applications. Its 4-inch suction and 3-inch discharge accommodate a wide range of system configurations. The Frame 3 build ensures sturdy support for tough-duty cycles, while the open box design makes it easy to inspect and service internally.
