Webthe pump. It is sum of discharge head, suction lift and friction loss. Total Head is a measure of a pump's ability to push fluid through a system. This parameter (with the flow) is a more useful term than the pump discharge head since it is independent of a specific system. The Total Head produced by a pump is independent of the nature of the ... WebAssuming that system calls for 100,000 BTU/hr, a circulator pump should have a minimum 10 Gallons Per Minute flow rate at a given pressure drop. For snow melt systems with a 50/50 mix of glycol and water, the above equasion is slightly different: 1 GPM = 11,000 BTU/hr. The next step is to calculate the head loss, or pressure drop in the system.
