ZX stainless steel self-priming pump

Product Overview
ZX stainless steel self-priming pump is an energy-saving pump product developed after absorption, digestion and improvement according to relevant technical data at home and abroad. The pump is a self-priming centrifugal pump, which has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life and strong self-priming capability. There is no need to install the bottom valve in the pipeline. It is only necessary to ensure that the pump body has a quantitative liquid before the work. This simplifies the piping system and improves working conditions.
 
Product Features
There is no need to install the bottom valve in the pipeline. It is only necessary to ensure that the pump body has a certain amount of water diversion before work. According to the customer's medium, there are cast iron material and 304, 316L material, medium temperature -20 °C-120 °C, flow rate: 3.2-600m3 /h Head: 10-80m speed 1450-2900r/min
 
Product usage
Mainly used in urban environmental protection, construction, fire protection, chemical, pharmaceutical, printing and dyeing, brewing, electricity, electroplating, paper, oil, mining, equipment cooling. It is suitable for clear water, sea water and chemical medium liquid with acidity and alkalinity and slurry with general paste. The viscosity of the medium is 100 centipoise and the solid content is up to 30%.
