Mud Pump

Drywall Mud Pump

is a specialized tool that efficiently loads joint compound (mud) into automatic taping tools like flat boxes, nail spotters, and corner applicators, significantly reducing manual labor, fatigue, and time compared to hand-filling. These pumps work by placing a tube into a bucket of mud and using a plunger mechanism (manual or cordless-powered) to transfer the compound through a hose to the desired tool, often with attachments like a "gooseneck" or "box filler" for precise delivery.
