The AMT 33 Series is a line of diaphragm pump that feature a two-stage, heavy duty forged gear driven transmission. Also known as mud or sludge pumps, they are designed to pump mud, slurry, sewage, and thick liquids that have the ability to flow. These pumps are available with gasoline or electric motor driver options. The built-in check valve allows for self-priming to 20ft after initial prime. The heavy duty forged gear driven transmission is designed to operate the pump at 40 strokes per minute for electric motors and 60 strokes per minute for engine driven. Each unit contains a 2in or 3in NPT steel suction strainer, two NPT nipples, and a wheel kit for portability.
