The Columbia Tall Boy mud pump is designed to fill mud easily by standing upright without bending, minimising back strain while loading pump.  As standard features for all Columbia Mud Pumps, the Tall Boy is built to extracting air-tight standards, making them the easiest to pump to prime.

Fabricated with an anodized aluminium cylinder, durable stainless steel shaft, a precision machined cast aluminium head, and a tough, smooth solid aluminium leg. The Tall Boy pump has larger capacity, extra height for use in a 30 gallon pale for those who want to cut down on mixing time. It has increased gooseneck diameter for faster filling.
