ZX series self-priming pump

product description
ZX self-priming pump is a self-priming centrifugal pump. It has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming capacity. There is no need to install a bottom valve in the pipeline. Before work, you only need to ensure that the pump has a fixed volume of fluid. This simplifies the piping system and improves working conditions.

Product features <br /> There is no need to install a bottom valve in the pipeline, just need to ensure that the pump body has a fixed amount of water diversion before work. According to the customer's use of the material is cast iron and 304, 316L material, the medium temperature is -20 ℃ -120 ℃ , Flow: 3.2-600m3 / h Head: 10-80m Speed 1450-2900r / min

Product use <br /> Mainly used in urban environmental protection, construction, fire protection, chemical industry, pharmaceutical, printing and dyeing, brewing, electricity, electroplating, papermaking, petroleum, mining, equipment cooling and so on. It is suitable for clean water, sea water, chemical medium liquid with acidity and alkalinity, and slurry with general paste. The viscosity of the medium is 100 centipoise, and the solid content can reach less than 30%.
