Structural features
Special submersible motor
● The whole series of motors are of H-class insulation,temperature
resistance reaching 180C°,protection level IP68,low energy consumption,low temperature rise,and high stability.Compared with ordinary motors,increase heat resistance by 60 degrees Celsius,extend the life,and the wiring chamber is sealed and separated from the stator and rotor of the motor,which brings double insurance. The motor bearing adopts the auxiliary oil tank structure,which increases the bearing service life.
Electric pump protection system
● The motor has a number of built-in warning sensors,including the
leakage in the wiring chamber,the motor cavity and the oil chamber, and the temperature rise of the bearing and the motor coil. The motor is equipped with water leakage monitoring,and the oil chamber is equipped with oil mixed water probes.There is comprehensive monitoring of motor operating conditions.
Impeller，volute
●The products adopt three-dimensional flow theory design.CFD calculation simulation,non-blocking,non-overload design,and are of high efficiency,wide efficient range,low energy consumption,and adopt double-flow channel non-blocking impeller.The passage of the pump body is wide,so the solids are easy to pass,and the fibers are not easy to entangle.The impeller is strictly balanced to minimize vibration and maximize the life of bearings and mechanical seals.
● Maximum flow capacity: The diameter of the solid in the medium should not be greater than 80% of the minimum size.
● Corrosive medium requirements: The products can not be used for pumping media that are highly corrosive or contain strong

● The cable outlet adopts special structure,which eliminates water leakage,electricity leakage,short circuit,and stator coil burnout caused by accidental factors such as artificial pulling,broken cable jacket,and cable aging,which effectively reduces the probability of failure caused by water in the upper part of the whole machine.
Cooling system
●The motor uses four sides to contact with water or air,which greatly improves its heat dissipation capacity. The motor bearing housing is in direct contact with water or air,which enhances the he at dissipation capacity of the bearing and greatly increases the service life of the bearing.According to the water level,cooling-jacket cooling system is provided to ensure that the motor can continue to run when it breaks the surtace of water.
Sealing system
● The products adopt patent structure,double sealed chamber structure,three sets of mechanical seals are used in the pump,and a buffer chamber is added. This greatly increases the reliability of the sealand completely guarantees the reliable operation of the products.The mechanical seal Adopts integrated installation.
