Reasons To Choose Cast Iron For Pump Production & Its Advantages

Casting is usually an essential method for producing parts that are used in machine applications where vibration is frequently a component. Casting parts can withstand vibration better than other methods. Cast steel has dampening capacity than cast iron, which can cause an excessive amount of disturbance and noise through clanging or screeching. Cast iron has a higher damping capacity than cast steel. When cast metals are unable to communicate sufficient strength and impact resistance, iron castings are used in their place. Casting companies that deal with iron make use of qualified engineers who are available to assist you in selecting metals, developing tools, prototyping products, and organizing manufacturing operations.Cast iron is utilized more frequently in the water supply and wastewater industries, whereas stainless steel is utilized more frequently applied in pharma sector.

Castings for pumps is a popular method used in the manufacturing industry for producing high-quality and precise parts for pumps. There are several reasons why pump casting is preferred over other methods of casting.

Why is cast iron the material that is most ideal for the production of pumps?

For many different applications, including the production of a variety of tools, cast iron is the material of choice. It is ideally suited for use in centrifugal pumps as well as bilge pumps. Cast iron develops certain mechanical and physical characteristics during the casting process that make it an ideal material for pump manufacturing. When pumps are manufactured for use in environments with high temperatures, the type of metal used is determined by looking at three different variables.

 The following are some advantages of Castings for Pumps

  1. Corrosion protection
  2. Maximum temperature limit
  3. The factor of expansion due to temperature
  1. Corrosion resistance:

The corrosiveness of the liquid will increase as the temperature continues to rise gradually. Cast iron has a weathering protection that is about average for a material. Therefore, cast iron is the material of choice for compressors used in applications that involve high temperatures.

  1. There is a maximum temperature limit

A thermal shock is something that can happen to the metal if there is an abrupt change in the temperature. This could occur if, for example, heated oil were poured into a chilly pump in order to start it up, or if cold water was sprayed on a hot pump while it was being cleaned. Pumps made of cast iron can perform to the user’s satisfaction at temperatures as high as 650 degrees Fahrenheit. They have a resilience that is significantly better than average to failure brought on by thermal stress below this temperature. Ductile iron that has been heat treated can withstand temperatures up to 1400 degrees Fahrenheit without failing.

  1. The rate of expansion due to temperature:

The temperature expansion causes the exterior components of the pump to undergo measurement changes, which can lead to the malfunction of the pump. Alterations to the pump’s dimensions have an effect on the operating tolerances as well as the interference fits. It is possible that components, such as the idler pins bushing in the casing and rotor bearing sleeve etc will lose their interference and be pushed out of position, which will result in the failure of the pump and the discharge of scalding liquid in the surrounding area. Cast iron has a thermal expansion coefficient of only 6.5, which is significantly lower than that of steel and malleable iron, which both have a coefficient of 7.0 for thermal expansion. Because of this, it is perfect for use in the manufacturing of pumps.

Due to its high precision, excellent surface polish, dimensional consistency, and cost-effectiveness, Castings for Pumps is an excellent option for a broad variety of applications and it is because of the overall quality of the casting.
