Liberty Pumps 451 1/2 HP Automatic Submersible Sump Pump with Wide-Angle Float
Brand: Liberty Pumps | SKU: 451
Product Overview
The Liberty Pumps 451 is a 1/2 HP submersible sump pump with an integrally wired, mercury-free wide-angle float switch for automatic operation. Its powder-coated aluminum motor housing and polypropylene components keep the pump lighter than a comparable all-cast-iron build, while the vortex-style impeller handles small solids in a residential sump application. Check basin diameter, float clearance, and discharge plumbing before ordering.
