Sanipump submersible sump pumps are designed in a highly-efficient manner that reduces clogging and power consumption. Heavy duty cast iron construction matched with stainless steel fittings and impeller plates for corrosion resistance improve the pumps life and performance, while top suction minimizes clogging and air lock. Available in 1/3 HP and 1/2 HP models, the Sanipump includes a flow shield that prevents drain pipe water from directly hitting the float and a non-wicking power cord that keeps water out of the motor. Upper and lower ball bearings permit quiet performance.
