Let’s check closer the details!
It’s easier for one to understand the reliability and overall value of the Zoeller M53 when checking all the details of the sump pump.
- Build and design features
With the sump pump having to run correctly in damp conditions, it’s natural that the outer part of the sump pump to be able to take the constant flow of water. It’s pretty standard for the internal components to handle an impressive load of pressures.
Unlike other competitors, the Zoeller M53 comes with a cast iron covering that protects the entire structure of the motor. The cast-iron makes the heat dissipate instantly into the water, fast and efficiently. The cast iron also protects the internal elements. Coated and dried with epoxy that eliminates the risk for corrosion (long time submerging in water causes corrosion), the cast iron impresses with the build.
A small hole on the bottom of the sump pump is going to let small amounts of water go through, without entering inside the body of the sump pump. Therefore, the risk for an air pocket developing between the switch guard level and the discharge above is rather low.
- Main outer elements: handle, discharge, and power cord
The Zoeller M53 is rather easy to carry around as it features a stainless steel handle. The power cord is almost 10ft long and has a strong and durability feel to it. Thanks to the sturdy build, the risk for electrical accidents is quite low.
The sump pump includes a 1-1/2in NPT discharge that takes most of the standard PVC or other pipes.
The 4pole motor helps the sump pump capable to deliver 1/3 horsepower with 1550RMP of maximum speed. According to the experts, it’s the highest power to obtain from a sump pump. We also notice an overheating switch that makes the longtime use safe with low risk for overheating.
The pump is entirely sealed hermetically, whereas a shaft seal made of carbon and ceramic doesn’t allow oil leaking from the motor. It also keeps the water or debris away from the inside of the sump pump.
- Impeller, switch, and safety features
You may go with a cast iron impeller or a plastic impeller (glass-filled metal insert). There is no clogging, and the performance is uniform. The grooves of the impeller help the motor draw water effectively, with minimal chance for blockage from the solid particles or the high water pressure.
Another great thing about the Zoeller M53 is the ability to switch on/off, through the switch assembly automatically. Afloat links to the two-pole switch (a vertical extrusion on the sides) — the motor switches on when the float rises due to the rise of water level. The float is made with long-lasting polypropylene, ensuring smooth operation in numerous situations.
The sump pump also features a switch guard for free operation without the common issues of the enclosure. The switch guard sticks out like a handle, providing free service. You need to change the switch guard from time to time, but it’s rather easy to do.
