Sprinkler pumps are used when the pump is located above the water draws vertically from 20' depth water or less. Sprinkler pumps use a single suction pipe to draw water from wells, multiple driven points or surface water such as from lakes, rivers and canals. Due to larger pumping volumes, pipe sizes on both suction and discharge ends are larger than that found in typical water pressure systems. To select a pump first determine the suction lift: the number of sprinkler heads going on at one time. Multiply the number of heads (x 3) for total demand. Review pump performance charts and find the pump that will deliver total demand or greater at 30 PSI. For transfer applications, select the pump with the best performance for your needs.
