AMT Sprinkler/Booster pumps feature 300 Series Investment cast stainless steel impellers for resistance against erosion caused by abrasive particles. All models self-prime to 20 feet. Single stage models feature dual volute design to reduce radial load on motor and a built- in check valve to ensure fast priming after initial liquid is added to the pump. Cast iron construction provides durability and low maintenance. Easy cleanout design includes replaceable dual 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 7-1/2 HP with Open Drip Proof (ODP) or Totally Enclosed Fan Cooled (TEFC) motors. • Single Stage Models Feature Removable Dual Volute Design • Available with 3/4 to 7-1/2 HP Single or Three Phase Motors Self-Priming Sprinkler/Booster Pumps • Cast Iron Construction with 300 Series Investment Cast Stainless Steel Impellers • Buna-N Mechanical Seal and O-Ring • Optional Viton ® Seal, Check Valve and O-Ring Available on Single Stage Models • 1-1/2˝ or 2˝ NPT Ports Sizes • Maximum Temperature 180° F • Maximum Flow 157 GPM • Maximum Head 180 Ft. • Self-Priming to 20 Ft. • Single Stage (379/365 Series) Two Stage (478 Series) Construction
