Liberty's FL Series of submersible effluent pumps are designed for durability and versatility. These heavy duty pumps feature cast iron construction and a stainless steel rotor shaft. Each pump can handle solids up to 3/4". The Liberty FL family includes seven different series: FL30, FL50, FL60, FL70, FL100, FL150 and the FL200. The number designations denote the horsepower of each series; thus the FL30 is a 1/3 HP series, the FL70 is a 3/4 HP series, etc. The family is also divided according to the amount of head each series can reach for a given application. The FL30 series is specifically designed for low head applications in STEP (Septic Tank Effluent Pumping) systems, LPP (Low Pressure Pipe) systems, mound systems, liquid waste transfer and commercial sump applications. The FL50, FL60 and FL70 series are designed for medium head applications, while the the FL100, FL150 and FL200 series are designed for high head purposes. Designations:

  • Models with the suffix "M" are manual models, while "A" denotes an automatic model.
  • The digit at the end of each model number represents cord length (2 for 25 ft., 3 for 35 ft., 5 for 50 ft.).
