Comprehensive Performance Curve
1. Seal of cable
Unique cable seal design eliminates the hidden trouble of cable leakage.
High quality disposable lubrication bearing offers worry-free operation.
3. Mechanical seal
Multi-tandem mechanical seal provides reliable and durable sealing performance and Max. abrasion and impact resistance.
4. Terminal box
Terminal box is completely separation sealed with independent seal assembly to the surrounding liquid to effectively avoid leakage caused by cable damage.
Squirrel cage induction motor, stator insulation class F (155 C) and each with overheating and overload protection, internal leakage and bearing temperature rise protection.
Shaft is made of high quality stainless steel, rotor part to be balance tested.
7. Oil chamber
Oil chamber lubricates and cools the mechanical seal unit and also is extra leakage protection (internal leakage protection unit)
8. Hydraulic model
Smooth geometric profile, excellent hydraulic model ensure accurate hydraulic performance.
