Submersible Sump Pump Advantage:
1, Everflowing NJQ series submersible Sump pumps have self mixing agitating fuction.Besides the main impeller, there is the agitation impeller which can agitate the sludge deposited on the water bottom into turbulent flow and pump the sand out.
2 .Higher efficiency and wear resistance .Impeller is closed type impeller, higher efficiency than open impeller.
All wear parts are made of high wear abrasive chrome alloy.
3. Low rotation speed ,980rpm, better wear resistance and long service life.
4.The motor is anti over-loaded motor with water-proof function.
5.No limited by suction lift. sand suction efficiency is high, dredging is more thorough.
6. If the sand is compacted, high pressure gun or excavator can be added to agitate and increase the medium concentration.
Sump pump service conditions
1.The power source is 50Hz/380V three-phase alternating-current supply, and the capacity of the substation transformator is two to three times of the rated capacity of the motor.
Power source can be ordered to design to match different frequency&voltage of different country/location or under your requirement.
2.The temperature of the medium cannot exceed 60 Celsius,If temperature is higher than 60 Celsius,jacket can be added to cooling by water.The medium does not contain inflammable or explosive gases.
3.The maximum weight concentration of the solid particles in the medium: the maximum weight concentration of the ash is 45% and the maximum weight concentration of the slag is 60%.
4.The submerged depth of the unit is not more than 30 meters, and not less than 1 meter.
5.The unit works in the medium vertically, and the working status is continuous.
