3HP 3P Sprinkler Booster pumps feature Investment Cast 316 SS closed impellers for high efficiency and resistance against erosion caused by abrasive particles. All models self-prime to 20 feet. Single stage models feature a built-in check valve to insure fast priming after initial liquid is added to the pump. Cast iron construction provides durability and low maintenance. Easy cleanout design includes replaceable volute/diffuser and casing o-ring for servicing.

Two-stage models provide additional pressure in fractional horsepower sizes for multi-sprinkler head applications. Type 21 mechanical seals handle maximum working pressure to 150 PSI. Pumps are available from 3/4 to 7-1/2HP with Open Drip Proof (ODP) or Totally Enclosed Fan Cooled (TEFC) motors. See Curve "G"
