The pump you choose must have the required GPH flow at the HEAD indicated in order to achieve that size display. The GPM flow at specific HEAD heights will be indicated in the manual or advertising for the pump in question TIP #1 - for multiple nozzles multiply the GPM required by the total number of nozzles desired. It is not necessary to increase the HEAD when adding multiple nozzles. Tip #2 - If the pump you are viewing indicates flow in GPH (gallons per hour) instead of GPM (gallons per minute) you can divide by 60. 900 GPH equals 15 GPM. Tip #3 - Try to select a pump that is slightly more powerful than required to allow for errors in calculation Tip #4 - All charts assume pump to be positioned at or near the nozzles. If the distance between pump and nozzle/ nozzles is greater than 10 foot additional HEAD will need to be factored in. Have Questions? We have answers! Use the "Contact Seller" link above!
