Little Giant submersible effluent pumps are ideal for removing effluents, dewatering and transferring gray water (household wastewater ejected from sink or bath) into a septic or sewage system for water treatment. These pumps are made of cast iron / polypropylene base material for excellent deformation & wear resistance. They further have high head design for pushing treated greywater out to a faraway drain field. They feature PSC (permanent split capacitor) motors with thermal overload protection to dissipate heat generated during the operation and produce low starting current & torque, thereby saving energy costs. Choose from a wide range of these pumps, designed to handle effluent, available in 1750 and 3450 RPM motor speed variants.
