Single stage, horizontal, centrifugal, self priming, end suction, mud / sewage pumps are of non-clog type. These have semi-open type, dynamically balanced impeller for vibration free operation and hence have longer life. These are best suited for applications where self priming action is required such as pumping water from docks, ports, vessels; pumping petroleum products, chemicals, effluent water, filter press; dewatering foundations, trenches & pits, sewage pumping etc
