Our recommendation

Zoeller vs Liberty both stand out in the market. However, If you want to install a sump pump with a float switch that will outlast the popular M53, we recommend the Zoeller M63 one-horsepower and the M95 three-fourths horsepower.


The reasons behind these suggestions are:

They have the best warranty in the market, lasting 5 years. Cast iron is used throughout and lasts for more than 25 years. Cast iron gives the pump weight, allowing it to remain fixed in the pit during continuous solid pumping. 

The float is puncture-resistant due to its robust polypropylene construction. The switching head features sturdy stainless steel protection to prevent the float from being entangled on the basin wall; upgraded switch. A bar uses to lessen the friction created by positive and negative close circuit activity, which reduces wear on the control and allows it to last considerably longer.

When the gasket between the pump housing and pump head becomes thin with age, an additional boot encloses the button for extra protection against moisture entry. 

During regular pumping, just 80% of the motor’s power uses. The engine can activate its reserve power if more horsepower is needed. The M63 pumps 2,040 gph at a 10-foot vertical height, while the M95 pumps 3,660 gph at the same height. 

Because a vortex impeller is employed, tiny particulates can flow through the pump without clogging the screen. The plug-led light displays whether or not the power to the pump is working correctly.
