Liberty’s cast-iron series of pumps feature a durable unibody casting and range from 1/4 hp to 3/4 hp. The 230 and 450 series pumps feature a finned aluminum motor housing providing 225% more cooling capacity than cast-iron and range from 1/3 hp to 1/2 hp. Both series feature powder coating for corrosion resistance, permanently lubricated upper and lower bearings and quick-disconnect power cords. The S30 builders-series are 1/3 hp submersible pumps featuring higher inlet ports to reduce potential for debris to enter the pump. Additional features include oil-filled motors with thermal overload protection, vortex-style impellers which reduce clogging and a three-year limited warranty.
