Product features

High-efficiency energy saving: the hydraulic model is designed by 3-D flow theory and calculated by CFD computational simulation,with the best performance in theory.HYdraulic components are made of metal mold,cast precisely guide blade mould is machined by CNC;guide blade shell and suction cone blank are cast by resin sand,solid flow channel is completely in accordance with design drawings,with efficiency higher, and wide high efficiency zone

High reliability:the design of the inlet flow channel is reasonable, the inlet water is uniform without vortex, with smooth running, the absolute concentricity o the pump shaft, and the excellent static balance of the rotor parts ensure that the pump has low vibration and low noise when running at high speed

Advanced technology:All parts using metal mold,precision casting,parts quality is reliable

Low maintenance: Reasonable structure,convenient assembly and disassembly, and simple maintenance

Inventory management:Reasonable inventory management,short lead time,fast delivery

Automatic monitoring:Equipped with intelligent water pump system independently developed,with automatic monitoring function

Structural feature

1. Special submersible motor

the whole series of F/H grade insulation,B grade temperature rise assessment, protection grade is IP68;the motor has low energyConsumption, low temperature rise, and high stability.It has better heat resistance and longer life than ordinary motors.the wiring cavity is sealed from the stator and rotor of the motor, with double insurance.the motor bearing adopts the auxiliary oil tank structure toIncrease the service life of the bearing.

2. Motor 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 bearding 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.

3. Hydrodynamic parts

the 3-D flow theory design and CFD computational simulation are adopted,with high efficiency and wide high-efficiency zone, and good cavitation performance;

Independently developed hydraulic model,high efficiency area is wide

Adopt metal mould, precision casting

4. Cable locking sealing system

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

5.BEarings

at the pump end is equipped with a thrust spherical roller bearings(the oil lubrication),withstand the axial thrust of pump,There are one cylindrical roller bearding and one deep groove ball bearing(grease lubrication)equipped with the top and bottom of the motor, withstand the radial force of rotor.The bearing running stable,and the motor shaft will not movement,so the bearing has little heat and no noise during the operation of the pump

5. Sealing system

the product applies a patented structure, the pump end adopts a combined double cartridge mechanical seal,and the motor side also adopts a single end mechanical seal.the structure makes the sealing performance of the pump reliable and running stable.
