Zoeller M53 Mighty-mate Submersible Sump Pump

Zoeller is a well-known brand and their sump pumps are highly recommended by plumbers. The Zoeller M53 Sump Pump is a well-made, high performing and reliable pump that lives up to the brand’s reputation. It has a cast iron motor, housing and a casing, as well as a sturdy thermoplastic base and features a well designed impeller design with metal insert.




What to expect?

This electrically waterproof submersible pump is a real beast and the great thing is that it has features like a cast iron housing which protects it from corrosion and parts made of stainless steel and engineered thermoplastic material that also ensure that the pump remains corrosion free. Also, it has a float operated switch to shut the pump down whet the water has reached its lowest level.


This pump is a workhorse and does extremely well in all residential applications.  You can also put it to use in kids pools, septic systems in addition to flooded basements. It is unique in that it can be found servicing commercial or residential fountains, or doing normal sump pump operation, or serving as a plumber’s or homeowner’s utility pump.


This float operated submersible sump pump has the following great features:

  • – Cast iron motor and pump casing with an epoxy coat for better corrosion resistance.
  • – Engineered thermoplastic base
  • – It has an engineered plastic vortex styled impeller
  • – The screws, guard and all the strews are made of stainless steel
  • – Is equipped with a 1/3 HP motor that can pump up to 43 gallons of water per minute up to 5ft but can pump up to 34 gallons of water to 10ft.
  • – Runs on a 60 Hz, 1725 RPM oiled and hermetically sealed motor
  • – The motor has an automatic reset and thermal overload protection
  • – The 1 1/3 NPT discharge can pass spherical solids with a diameter of 13mm


This is a high performance pump that has a tried and tested design. Built to last for several years, this sump pump has a solid construction, synonymous with its great efficiency- it pumps out 2580 gallons of water per hour up to a 10ft vertical lift.

It is a great sump pump that works well for homeowners who have to deal with flooding during heavy rains as well as those who need to empty their pools, ponds and aquariums.  This pump is not loud so you will hardly know it is running.

With a cast iron casing, a volute made from engineered plastic, this pump is meant to last. The vortex impeller is designed not to clog allowing 12” spherical solids through. The pump is fitted with a powerful 60Hz 1775-RPM oiled-filled hermetically sealed motor.  Has the capacity to pump to a maximum head of 19.25 feet.

The clog free design is a great benefit. This pump is designed to allow ½ spherical solids easily. There is no screen that requires constant cleaning. The float is a great feature because it activates the pump to switch on or off when water levels rise or fall.


Even though it’s a reliable pump, a good warranty cover gives you the much-needed peace of mind. However, there is a caveat here. The warranty for the sump pump starts on the date of manufacturing and goes on until the said warranty period expires. So, be sure to check the date of manufacture before buying one.

Although they are easy to service and run reliably, you cannot just hook them up to power and forget about them.

Another disadvantage that most people have identified in their reviews is that the switch has to be replaced every few years. How often this will happen will depend on the number of times the pump is switched on and off. This is not a deal breaker as such because in any case a switch is not made to last forever regardless of how long the rest of the pump holds up.


If you don’t have a quality sump pump, you should think about purchasing and installing a good quality sump pump such as this one. Overall this is a great pump that is designed to survive the worst situations, and because it is a Zoeller, you know it is great quality.
