Housing for all VISUN water pump is produced by VISUN it self , high quality metal is used in cast iron water pump housing , Never use recycled materials instead.Shell casting is designed in strict accordance with OEM sample, obeying OE structure and wall thickness to ensure the strength and weight of shell . The shell is finished by precision machining, and the machining surface reaches the designed dimension tolerance, shape and position tolerance and surface roughness to ensure the good coordination between the shell and the bearing and the sealing of the installation
The pump impeller is made of cast iron.The blade on the pump impeller plays a major role. The shape and size of the pump impeller are closely related to the performance of the pump.The impeller is the core part of the pump, and it is the main factor affecting the working efficiency.Under specific working conditions, if the impeller design is not good, there will be hydraulic loss and clearance loss at the pump inlet and blade.
As the engine as the core of the automobile is developing towards the direction of high power and high efficiency, higher performance requirements are put forward to the pump bearing.For example, it has higher thermal resistance, greater bearing capacity and good sealing performance,VISUN use C&U bearing for our water pump , biggest bearing supplier in China , Under the same radial size condition, its bearing capacity is greater than the general type of bearing,Good rigidity, rotation, simple structure, convenient assembly and disassembly.
For water seal,high quality Silicon carbide-graphite Seal is widely used in VISUN water pump , with advantage of High hardness, high wear resistance, low coefficient of friction, good oxidation resistance, good thermal stability, low coefficient of thermal expansion, high thermal conductivity and thermal shock resistance and chemical corrosion resistance .
