This type of self-priming Cummins diesel engine sewage water irrigation pump set is a new structure product develped after repeated study of domestic and foreign similar technology. This pump group sets combines the advantages of self-priming and non-block sewage discharge ability, adopt diesel engine drive, when using, do not need to install bottom valve and no priming water needed. Pump group can discharge impurity medium containing bulk solids and fiber, and can be widely applicable to municipal sewage and flood control, agricultural irrigation, etc.

This pump group has the features of simple structure, good self-priming performance, high sewage discharge capability, high efficiency and energy saving, convenient operation and maintenance, or outdoor movable design, is the domestic initiative in diesel pump series.
