Benefits of Cast Iron in Submersible Pumps
Cost-Effectiveness
Material-wise, cast iron is generally less costly as compared to many other material options, providing an affordable choice for the cost-sensitive buyer to still have a good pump.
Its low entry cost does not, in any way, impinge on its performance; cast-iron pumps can, in general, handle various tasks efficiently.
This cost-effectiveness is the reason for the high demand for cast iron instead of people opting for a high-performance but quite expensive material.
Structural Integrity
Cast iron is strong and inherently provides a well-maintained structural integrity under heavy loads and high pressures.
This applies mainly in greater-scale processes where durability is imperative.
The pump life is increased by endowing cast iron with a proper stress-bearing capability, resulting in fewer replacements.
Vibration Damping Properties
It eliminates avibrinatural vibraitaonnal sources of reinforcement, which considerably improve the performance of submersible propellers.
