 3. Consider Material and Design

 4. Check Pump Performance Curves

In firefighting systems, propeller pumps also play a crucial role. They provide the necessary pressure and volume of water needed to combat fires effectively. Their capability to move large quantities of water quickly makes them a reliable choice for fire departments, particularly in high-risk areas where rapid response is critical.

   - Review the performance curves for the selected pump models to ensure they meet your flow rate and head requirements.

In addition to its shape and size, the material used for the volute's construction is also important. Typically, materials such as cast iron, stainless steel, or thermoplastics are employed, chosen based on factors like fluid characteristics, temperature, and pressure. For example, corrosive fluids may necessitate the use of more durable materials to prevent degradation and ensure longevity.

   - Verify that the pump operates efficiently at the desired operating point (usually within the best efficiency range).
