1. Product Summery
Self-priming pump researched by our company as a new generation self priming pump which can pumping and suction water without bottom valve, vacuum pump, and pouring water, but with itself’s suction vacuum device, owns strong self-priming capacity, short time self-suction, long uselift etc characters, which filled branck domesticly, finishing the history that pump back-pouring.
2.Performance Character:
a. Unique Suction Vacuum Device, makes the suction pipe from the water level always at vacuum condition, decrease the damage from impeller cavitation erosion, raise the efficiency of pump.
b. When the pump’s “water loss” phenomenon appear, it also can suction and discharge water though the vacuum device, reached auto recovery anytime when water lossing.
c. Though the clutching machine, the suction vacuum device can achieve seperation and reunion automaticly or by hand, to achieve the effect of full-auto operation, extend uselife and saving resource.
3. Usage Application
The corporation produce high self-priming pump series are including SWB series self-priming sewage water pump, SD series high self-priming multistage centrifugal pump, IS series high self-priming clean water centrifugal pump, OW series high self-priming double suction pump, SFB series strong self-priming non-corrosion chemical industry pump, XBD/XBC high self-priming firefighting pump, widely used for convery of oily sewage, rain water, industrial waist water etc medium which contians tiny solid grain, water drainage of petroleum, chemical-industry, pharmancy, electric power, mining mountain deep well, farm irrigation municipal drainage, firefighting contruction etc application area.
