[Three rain valve to recommend star products - mechanical seals] Introduction: ZW Self-priming sewage pump is self-priming pump sewage pump WQ25-35-5.5 achieve self-priming pump design time he was through idle will draw air from the air-containing medium WQ100-7-5.5 pump, you know the media will pump filled with complete self-absorption. Their structural difference is not very big, but not very different installation methods, then is the connection type impeller diameter, the motor and the pump, whether with the self-absorption devices. Automatic stir sewage pump automatic stir submersible sewage pump with cutting function, with more impurities in the waste water situation, such as a toilet paper WQ80-10-5.5 pumps, stool, or even women rushed to the toilet in the towel towel also can play broken, those are just different stainless steel materials extend the life of the functionality essentially no difference. The main parameters of submersible sewage pump for the main control parameters selected pump flow, head, power, efficiency, work pressure, NPSH and so on.
