We are offering submersible sewage pump.Outlinedbearing: skf chooses import bearings or ntn bearing. The reasonable bearing configuration, to prolong the service life of the pump. Cooling: built-in cooling system, no matter in liquid surface or motor is in liquid surface, all can make pump working normally. Pumping the liquid from the body part of pump cycle to cooling tube and cabinet take the heat generated between motor. Need external cooling, cooling set can be separated, and with the pump body and individual cooling system connected. Motor: motor for class f insulation, the highest working temperature of 155 , effective sealing make motor protection grade for ipx8. Mechanical seal: choose burgmann germany mechanical seal, two way mechanical seal series independent work. Make motor and pump seal to space, for motor provides double protection. Pump side for tungsten carbidetungsten carbide materials, motor side for graphitesilicon carbide. Oil room: oil lubrication and cooling mechanical seal can be, and can prevent liquid penetrant to motor of the additional security function. A certain amount of air inside can reduce indoor pressure in the accumulation of oil rise.Applicationwq series submersible sewage is mainly used for municipal engineering, industrial building, hotel, hospital, civil air defence, mining and other industries, can be used to send row with solid particles and all kinds of long fiber sewage and waste water, rain and city life in the water.Working conditionsflow is 10 to 6000 m3 hhead is 6-62 mfor 0 temperature of the liquid-60 the maximum pressure 16 barproduct features1, with big port anti-clogging hydraulic parts design, greatly improving sewage capacity, can effectively through the pump fibre material 5 times of pump diameter and about 50% of the solid particles.2, design reasonable, reasonable motor, high efficiency and energy saving effect.
