Notes:
  • Test results are averaged, and therefore should be considered approximate.
  • Tests performed with 316ss head, Teflon® diaphragm, 1/4 inch diameter hose x 5 ft. line at 75° F, using a std. 1725 rpm motor at 60 Hz.
  • These test results are for reference only, and are intended to help provide information to the user when determining which pump to buy. Actual pump performance will depend upon the users' applications.
  • For 50 Hz operation, reduce output by 17%
