The ZB series self-priming centrifugal pumps of our company, short for self-priming pump ,manufacture in strict accordance with the standard JB/T6663.1-93,which mainly consist of impeller,casing,sealing,bearing body etc, apply to convey clear water or others whose properties similar to water.

The medium temperature can’t exceed 176°F.

It has two type of drive, one is the power machine connect with the pump directly by a Coupling, another is the power machine and pump rotate through the pulley. The power machine can be the diesel engine or electric engine, the user can select as required.

Scope

Primarily supporting the use of light-small sprinkling machine, and fixed permanent or semi-permanent sprinkler system, widely applied to irrigation of various farmlands, orchards, vegetable farms and nursery garden, it can also use in pump unit for water supply and drain of urban construction, factory and mine.

principle

Self-priming pump is different with centrifugal pump, you should fill the pump with water before start, then the impeller rotate with high speed under the engine, when the impeller turns,the water pressure at the entrance of impeller reducing and the entrance of the impeller lower than atmosphere pressure. While the water pressure along the direction of impeller radius ceaselessly rising and outdistance atmosphere pressure, formed a certain suction in water inlet. Under atmosphere pressure, the lower water push the inflow valve, enter into pump case along water inlet, dumped into water outlet by impeller. While the self-priming pump needn’t to be filled with water, but the source water must be fast-flowing and has fall head. It is exactly use the impulse of falling and flowing water, drive the impeller to pump up water. The suction of the self-priming pump is not exceed one atmos, around 11meters.
