1.Balance disc
Axial force is dynamic balanced that has excellent and reliable balance result
Spiral seal construction is designed that leakage is small and volumetric efficiency is high
2.Inducer,first stage impeller,impeller,diffuser
High cavitation resist design that satisfies with low cavitation requirementsExcellent hydro model is adopted that have high efficiency and wide high efficient range
Metal mould,accurate roughcast and digital machining are adopted
3.Seal
Good quality mechanical seal without any leakage while starting,running and stopping
Self circulating cooling design,have long operation life,convenience in assembly and disassembly,and simple maintenance
4.Bearing
Rolling bearing support with thin oil lubricated and water seal construction
Axial limits design for rotor in non driven end that improves operation life of mechanical seal
Temperature and vibration monitoring nozzle is preserved for bearing box,which can be provided according to requirements
5.Supporting method
Center support is suitable for delivering media with high temperature
Even thermal expansion,rotor without bend,and operation is stable
6.Rotor part
Design thickened that have good rigidness and high critical speed
Strictly balance tested that operation is more stable
