1、 Overview
The ZX self-priming pump is designed according to the requirements of users in the chemical industry. The pump adopts an external mixed self-priming structure. Before the first start, the pump body solution must be filled into the pump body, and frequent starts in the future do not require water injection or vacuum pumping. It is easy to operate, safe and convenient. Truly achieved one-time drainage and lifelong self-priming.
2、 Characteristics
ZX self-priming centrifugal pump has strong self-priming function and other advantages. There is no need to install a bottom valve in the pipeline. Before operation, it is only necessary to ensure that a certain amount of liquid is stored in the pump body. Suitable for urban environmental protection, construction, fire protection, chemical, pharmaceutical, dye, printing and dyeing, brewing, electricity, electroplating, papermaking, industrial and mining washing, equipment cooling, etc. With the rocker nozzle, the water can be washed into the air and dispersed into small raindrops for spray. It is a good machine for farms, nurseries, orchards and tea gardens. Suitable for clear water, seawater, chemical media liquids with acid and alkalinity, and slurries with general paste like properties. It can be used with any type and specification of filter press (medium viscosity ≤ 100 cP, solid content up to 30% or less), and is an ideal pump for feeding slurry to the filter press for pressure filtration.
