4 inch self-priming sewage pump

Product Description

SP-4 self-priming sewage pump is our latest generation product base on US technology and craftwork. It is designed for economical & trouble-free operation in handling solid-laden liquids and slurries.


The self-priming centrifugal SP Series is the standard for industrial and sewage applications. The heavy duty construction and easy-to-service design have made T Series pumps the standard in the industry. The combination of different sized pumps, impeller trims and speed variations ensure that the correct capacity pump will be matched to the exact requirements of your system, whether it's a small sub-division or a large waste collection system. These pumps feature a large volute design that allows them to reprime automatically in a completely open system without the need for suction or discharge check valves - and they can do it with the pump casing only partially filled with liquid and a completely dry suction line.
