Pumps are essential for liquid HVAC systems. They circulate the hot water and chilled water to where it is needed to keep us comfortable. After you calculate the system flow and pressure drop, the next most important step is selecting the pump with paper pump curves or web-based selection applications. We will review the information on the pump curves and how they will help you make a better selection.

The second section of our training will cover Net Positive Suction Head (NPSH). Every pump has a minimum inlet pressure to avoid detrimental cavitation. We will review the principles of NPSH, calculate NPSH available and how we can avoid pump problems.

Finally, we will review the different pump options and configurations. What works and what provides the most value? We will review circulators, inline pumps, base mounted end suction pumps, horizontal split case pumps, and vertical turbines pumps.
