ZCSB series of self-suction pump diesel generating units in the repeated study of similar technology at home and abroad based on the successful development of a novel structure of the product. Set the self-priming pumps and sewage in one plug, the use of diesel-driven mixed-type axial return outside, and through pump body, rotation Road leaves the unique design, when used at the end do not need to install valves and irrigation water. Suction pumps can be ranked with large particles of solid and liquid impurities filament, can be widely applied to municipal sewage and flood projects, such as agricultural irrigation. The pumps have a simple structure, good self-priming, sewage capacity, high efficiency and energy saving, the use of easy maintenance, all-in-one type of movable or outdoor design features of products in the diesel pump in an internal initiative.
