    Look at the specification chart before you buy
  

*by J***. on Reviewed in the United States on May 31, 2019*

This pump only delivers 4309 GPM at 15 PSI according to the mfg. performance chart. Most irrigation sprinklers need 35 PSI minimum to operate.  At 35 PSI the delivery is 51 GPM or 3078 GPH.  Make sure your system will operate with these capacities and pressures.
