The Zoeller M98 and M53 are top of the line sump pumps but each model has pros and cons. We put together in-depth research comparing both models to see which pump is best for your home. Keep reading to learn more about both the M98 and M53 Mighty Mate.
M53 and M98 Compared
Key Differences
While both Zoeller sump pumps are made by Zoeller there are a few key differences that set them apart. The M98 is more expensive than the M53 but both are affordable on any household budget (less than $200). With the higher cost, the M98 provides a higher flow rate of 72 gallons of water per hour thanks to the 1/2 HP motor compared to 43 GPH and 1/3 HP on the M53. This might not seem like a large difference but if you receive lots of groundwater or have a high head height you should invest in the extra horsepower.
Another key difference that sets these two pumps apart is the base material. The M53 Mighty Mate has a thermoplastic base that is not as durable as the solid cast iron base of the M98.
Keep in mind that both pumps will need a check valve to protect your basement!
