AMT Self-Priming Sprinkler PumpAmerican Machine & Tool Series Self-Priming Sprinkler Pump

INDUSTRIAL DUTY = NO PLASTIC PARTS

AMT Sprinkler/Booster pumps feature 300 Series Investment Cast Stainless Steel closed impellers for high efficiency and resistance against erosion caused by abrasive particles. All models self-prime to 20 ft. Single stage models feature dual volute design to reduce radial load on motor and 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 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.

Select the pump curve from the charts on the right.
Total Head in feet is calculated as follows:
(Desired Pressure x 2.31) + elevation difference from water to highest point in the system.
For example: 5' elevation difference from water to pump and 10' elevation difference from pump to highest point in the system with 30 PSI desired at the end on the system would be calculated as follows:
5 + 10 + (30 X 2.31) = 89.3
Pump Curve E would be able to supply about 20 GPM

NOTE: If you are running a large amount of water line then friction losses can cause additional head.

Sizing a pump system can be tricky, Please contact us if you need any assistance in the sizing of your pump system.
