Cast iron multistage pumps are widely used in various industrial and commercial applications where high pressure and fluid transfer are required. These pumps consist of multiple impellers (or stages) arranged in series to increase the pressure of the fluid being pumped. The use of cast iron for the pump casing makes these pumps durable and reliable, capable of handling different types of fluids, including water, chemicals, and oils.

The key benefit of a multistage pump is its ability to achieve higher pressure outputs compared to single-stage pumps. Each stage increases the fluid pressure progressively, making multistage pumps ideal for applications such as water supply systems, boiler feed pumps, and irrigation systems.

These pumps are often chosen for their robustness and efficiency, particularly in industries such as agriculture, municipal water systems, and power plants. Their corrosion-resistant and long-lasting cast iron construction also contributes to their popularity in demanding environments where wear and tear are frequent.
