*CV-series are designed for solid handling submersible pumps, enclosed with vortex impeller with spherical clearance 35mm and 56 mm are ideal for pumping sewage, wastewater and fibrous solids. *Motors are protected to IP 68 and class F 155 insulation standards. Over-current and over- temperature protector prevents the motor from overheating and abnormal running. *Maintenance free C3 radial clearance deep groove ball bearing lubricated with special test high-quality lithium soap base greases are suitable for high speed running and long life service. *Double mechanical seals in a separate oil chamber can fully protect the motor from water infritration. *A high efficiency hydraulic section and dynamically balanced impeller can reduce the level of noise and vibration. *The reliability-base design and the strongest quality assurance keep the low-cost installation and minimum maintenance costs
