When selecting a centrifugal pump for an HVAC application, several key factors must be considered. These include the required flow rate, pressure head, and power consumption, as well as the fluid properties, such as temperature, viscosity, and density. The pump’s materials of construction, seal type, and bearing design must also be suitable for the application. Additionally, factors such as noise level, vibration, and maintenance requirements should be considered. A thorough understanding of the system’s requirements and the pump’s performance characteristics is essential to selecting the right centrifugal pump for the job.
