Is your Mud Hog diaphragm pump losing suction or slowing down? Don’t risk job-site downtime or lost production.
Ken’s Distributing Company supplies OEM-fit Mud Hog replacement diaphragms designed for trash and dewatering diaphragm pumps used across construction, municipal, industrial, and agricultural operations.
The diaphragm is the flexible wear component that separates the air and liquid chambers, creating the vacuum and pressure needed to move water, slurry, and debris. Replacing worn diaphragms restores full suction lift, flow consistency, and overall pump performance.
We supply both individual replacements and bulk orders of 15 units or more, with discounted pricing for contractors, distributors, and rental companies nationwide.
