Why is cast iron the best choice for making pumps? Cast iron is used for many purposes, including the manufacture of pumps. Cast iron is ideal for sump pumps and centrifugal pumps. Cast iron has some mechanical and physical properties that make it ideal for pump manufacturing. Three factors determine the right metal for high-temperature applications. 1. Corrosion resistance The liquid becomes more corrosive as the temperature rises. Cast iron is relatively resistant to corrosion. Cast iron is the preferred choice for pumps that are used in high temperatures. 2. Maximum temperature A thermal shock is an abrupt temperature change that causes metal to suffer. This can happen when you pour hot oil into a cold-pump to start it up or spray cold water on it during cleaning. Cast iron pumps can be satisfied at temperatures below 650 degrees Fahrenheit. They are able to withstand thermal shock below this temperature with a good degree of success. Ductile iron that has been heat treated can withstand failures up to 800 degrees Fahrenheit. 3. Thermal expansion coefficient: Thermal expansion can cause dimensional changes in external parts of the pumps which could lead to the failure of the pump. Dimensional changes can affect the running clearances of the pump and interfere with the fittings. Parts such as the bushing, idler pins and bushings in the casing will become interfering with each other and may be forced out of place. This could lead to pump failure or an explosion of hot liquid. Cast iron has a coefficient of thermal expansion of only 6.5, which is lower than that of steel or ductile iron (which have a coefficient of 7.0). It is therefore ideal for pump manufacturing. Both malleable and ductile iron are very machinable, resistant to wear, vibration damping, and have low notch sensitivity. They are also resistant to heat, strong, tough, and ductile. Cast iron pumps also have thicker walls that are more durable. Cast iron pumps are resistant to knocks and shocks. Cast iron is easy to maintain and repair in the event of damage. Cast iron has an acid pH of 6 0r high. It corrodes and forms a coating on its surface. This protects the pump against further corrosion. Cast iron is more durable than cast steel and has better casting performance. It also offers mobility and wear resistance. Sump pumps generate heat, and a sump made of cast iron distributes heat evenly to the motor. This increases the life expectancy of the pump. Cast iron is resistant to high temperatures and has a low risk of internal shock. Cast iron is cheaper than other metals, and parts can be made quickly. Cast iron increases the overall pump's capacity.
