development of pump energy saving products.Self-priming centrifugal pump, the pump and other pump does not have the self-priming capacity, etc.Such as corrosion resistant mechanical seals and stainless steel material can call some of the chemical, pharmaceutical acid and alkali medium. 
Second, the product features
 
1, the pump with self-priming function, do not need to install the bottom valve in pipeline, only to ensure storage in pump body before work are quantitative liquid can have "a drainage, life-long self-priming" function.So both simplifies the pipeline system, and improved the working conditions.
2, has a compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life. 
Three, use the product
 
1) suitable for urban environmental protection, construction, fire control, chemical, pharmaceutical, dyes, and dyeing, brewing, electric power, electroplating, papermaking, oil, mining, equipment cooling, tanker unloading, etc. 
(2) apply Yu Qingshui, sea water, chemical liquid medium with acid, alkalinity and with general mushy slurry (medium viscosity 100 mile, or less under the solid content of 30%). 
(3) mount a rocker arm sprayer, the water can go into the air, a small drips to spray, is a good tool for farm, nursery, garden, tea garden. 
And (4) can be matched with pressure filter of any model and specifications, sending size belt filter to filter the most ideal auxiliary pump.  
Fourth, working conditions
