Thelco Pump of the Day: Worthington D814 6x4x8 with 7.70” T&B Impeller

When precision matters, the Worthington D814 6x4x8 steps up with confidence. This robust, all-iron pump features an impeller trimmed and balanced to 7.70 inches—just shy of its maximum capacity of 8.00 inches. Designed for reliability, it delivers consistent flow in demanding industrial applications. Whether you’re handling process water or moving slurry, this pump offers the performance you expect from a D814.

Engineered for Versatility

Because the D814 6x4x8 supports a range of impeller diameters, it can be tuned to meet specific flow and head conditions. At Thelco, we trimmed this impeller to 7.70 inches, optimizing its efficiency while staying within the design limits. This setup enables you to operate the pump closer to the Best Efficiency Point (BEP), ultimately reducing wear and increasing service life.

Why the D814 6x4x8?

The D814 is part of Worthington’s proven D800 series. Its design includes replaceable wear parts, a back pull-out feature, and compatibility with various sealing options, including mechanical seals and packing. That kind of flexibility makes it a preferred choice across municipal, commercial, and industrial sectors. When properly configured, the D814 minimizes downtime and streamlines maintenance.
