IS series single-stage end-suction (axial intake) centrifugal pump is an energy-saving pump designed by teamwork in the whole nation, it is improved on a basis on model BA, B and other single-stage water centrifugal pump. The advantages: its hydraulic capability is distributed reasonably, wide option for user, conveniently check and repair, the efficiency and throw is up to advanced international level.

Precautions for use of clean water pump:
1. Check whether the seals of exhaust hole, clean water pump, drain hole, oil drain hole and cable joint are loose, and it is necessary to tighten them.
2. Check the clean water pump cable, such as a broken or cracked one, it should be replaced to avoid leakage.
3. Before starting, check all circuits and switches, check whether the connection is correct and reliable, and then turn over the ground for 3 to 5 minutes (the time should not be too long to avoid damaging parts or burning motor windings), and check whether the rotation direction of the motor is correct. Assuming that there is no doubt above, it can only be used in water.
4. Use a 500 volt megger to check the insulation resistance, which should not be less than 0.5 ohm, assuming it is lower than this value to initiate drainage and vent, monotone or dry.
5. New or changed completely closed box of clean water pump, use for 50 hours, should check whether the seal is excellent, and then check once a month, check the sealing between the motor stator and rotor of the shielding sleeve together is an excellent condition.
6. After one year's operation, the corrosion of the pump should be monitored to remove rust and paint. If the water pump is not used for a long time, it should be carefully checked by the housekeeper with monotonous ventilation.
7. In the use of clear water pump into the water, can not do the cable force. The gallows tethered it to the mouth of the well with a rope. Electric pump in 3 meters, 0 minimum depth, maximum depth of water. 5 m (from the center of the sun impeller).
8. In the operation of the clean water pump, it is necessary to check the change of water level at wells. The motor should not be on the water surface or mud, so as to avoid damaging the motor winding cooling. Should be in the well water level change, lift the pump at any time, such as cut water or interrupted, it is necessary to stop the machine immediately to find out the cause, or check. The cable shall not collide with the wall, so as to avoid the wear of the well water along the cable core into the motor.
