The MNC Self-Priming Non-Clog Pump is a robust and high-performance centrifugal pump specifically engineered for applications that require quick self-priming and the ability to handle dirty water, sewage, and slurry containing solid particles.
It features a semi-open impeller design that allows the passage of solid particles up to 40 mm, making it ideal for pumping water with mud, sludge, or suspended solids. The pump is designed to automatically remove air from the suction line without needing a foot valve, thus ensuring easy operation and reduced maintenance.
