Technical Specification & Payment and Trade Terms & Delivery and Packaging

The selection of materials for water pump accessories is very particular, not only considering material hardness and toughness, but also considering properties such as heat resistance and wear resistance. Reasonable material selection can increase the service life of water pumps and provide users with a high-quality product experience.
Cast iron materials
The carbon content of cast iron is generally between 2.5% and 4%, which belongs to iron carbon alloys. There are three main forms of cast iron, including gray cast iron, malleable cast iron, and ductile iron.
Malleable cast iron has strong toughness and plasticity, and is commonly used to cast the outer shell of water pumps. The water pump outer shell needs to have heat dissipation function, so many heat dissipation fins need to be cast. This requires extremely high toughness and plasticity of the material, and both too hard and too brittle can cause the pump shell to fracture.
Ductile iron is a type of cast iron with good comprehensive properties. Due to its mechanical properties being close to steel, and its casting and processing properties being better than steel, it is usually used as a substitute for cast steel. Commonly used for casting accessories such as pump bodies, impellers, and pump covers.
Stainless steel material
Stainless steel is the abbreviation of stainless steel and acid resistant steel. There are more than 100 types of stainless steel in the industrial field. Austenitic stainless steel is a commonly used material for casting water pump accessories, which has good corrosion resistance. It is commonly used for pump bodies and impellers that pass through water, avoiding water pollution and ensuring water transmission safety.
Stainless steel materials are widely used in water pump accessories, and they all have certain working conditions. In the field of special media such as chemical and petroleum, water pump materials are required to have properties such as wear resistance, corrosion resistance, and high temperature resistance.
Rubber materials
In addition to rigid metal materials, rubber materials are also indispensable in the assembly of water pumps, as they mainly play a role in sealing and buffering. For example, tetrafluoroethylene has corrosion resistance and high temperature resistance, and is commonly used in the manufacturing of mechanical seals. Its applicability is also very wide, suitable for almost all media up to 250 degrees Celsius.
In addition, fluororubber is also a commonly used sealing material, which is widely used in the application of O-rings to help fill the connection gap of water pumps, avoid connection leakage, and cause safety hazards. Fluorine rubber materials are also applied in some dynamic ring seals, whose toughness and wear resistance properties can compensate for the vibration caused by pump shaft movement, reduce the vibration of the entire machine, and extend the service life of the water pump.
