Zoeller M53 Sump Pump is built with quality.
High quality epoxy coated cast iron is used for the motor and pump housing and switch case. This protects again corrosion.
♦ The 3/10 HP pumping capability is comparable to most competitors 1/2 horse power pumps because Zoeller motors are very efficient. They are not canned motors with a housing slide into another pump housing. Zoeller motors are built directly in the pump housing. This aids in dissipating heat and thus reduces overheating.Zoeller Pump Manufacturer provides the following Product Description for the M53 Mighty Mate.

Measurements
Zoeller Pump Manufacturer provides the following Pumping Performance Flow Rate Specifications.
M53 has quality features and is a work horse for homeowners with an average amount of water during a heavy rainstorm.
This sump pump is built to last for average water conditions. This pump is cast iron - pump housing. The volute is engineered plastic and the impeller is glass-filled with a metal insert to provide additional strength.
This sump pump will not clog. It has a vortex impeller design which prevents clogging. It is also build to pass 1/2 inch spherical solids. Many competitive brands do not provide this feature. It has no screen to clog.
The vertical float switch assembly is encased in cast iron. The float is buoyant and made of polypropylene, solid and made to last. Like any other sump pump the switch will not last forever and needs to be changed every 2-3 years depending upon amount of usage. The design of the float switch decreases its tendency to get hung up.
The 1/3 HP efficient motor is powerful. It can pump 43 gallons per minute (or 2,580 GPH) at 5 foot lift and 34 gallons per minute at 10 foot lift (or 2,040 GPH). It has a greater pumping capacity than competitor 1/2 HP brands. Maximum head it will operate at is 19.25 feet.
The motor is 60 Hz, 1725 RPM, oil-filled, hermetically sealed, has automatic reset thermal overload protection. Voltage is 115V. Amps rating 9.7. The sleeve bearings run in a bath of oil. It has a carbon and ceramic shaft seal. It can handle a maximum temperature of 130 degrees F.
The screws, bolts, pump handle, guard, arm, and seal assembly are stainless steel. The cord is 9 foot, UL Listed 1-wire neoprene cord and plug.
The size of the pump is a smaller footprint with height of 10 1/16 inches and maximum diameter of 10 3/32 inches. It will easily fit into an 18 inch diameter pit along with a backup sump pump.

As for the cost, the price is very competitive with other name brand pumps of same pumping capacity. In fact Zoeller is a better deal since it has more quality features. A glass filled metal insert in the impeller, the non-clog vortex impeller, solid vertical float system are some of the examples of additional quality.
The cost of the pump is somewhere around $200. This is a good deal!
Consumers give the M53 Mighty Mate a well above average rating (4.6 stars in a 5 Star Rating Scale) as a submersible sump pump selection. Of the over four hundred online consumer reviews, 86% of consumers rated it 4 stars and above with 76% giving it 5-stars.
14% rated it 3 stars or lower. The most common reason for a lower rating was because of float switch failure. The switch and gasket last somewhere between three and eight years depending upon usage and pit conditions. The float is puncture proof and therefore cannot fail because of filling with water. The switch will fail after so many uses. It is best to change the switch between three and five years. The switch costs around $30 and is easy to replace.
The pump is not light - twenty-one pounds. The weight prevents the pump from moving around during operation. It may take some effort to remove it from the pit when replacing the switch.
The solids handling design is good. There is no bottom or top screen to remove. The impeller is made to handle up to 1/2 inch solids. If you have a pit frequently filled with debris, it is recommended you remove the base of the pump periodically to check on the impellers free movement; otherwise cleaning should not be necessary. When checking the impeller also check the two small holes by the impeller and the discharge port to make sure they are not clogged. Clogged holes could cause an airlock which means the impeller would move freely but the air pocket would prevent the pushing of the water.

Here's what some consumers are saying about the Zoeller M53.
Finally had to replace my Zoeller M53-D pump after 12 years of service, actually I didn't really replace it I just bought another one, I will put a new switch in the old and keep as a spare. We have a very high water table here and the pump runs every 2-3 minutes most of the year. You won't find a much better pump out there that can run like this for 12 years and only need a $20 switch. Oil filled for long life, quiet and reliable. I'll never run anything other than Zoeller.
I recommend buying the Zoeller M53 Mighty-mate Submersible Sump Pump, 1/3 HP with check valve if you are replacing your sump pump.
The valve keeps the water from backing up adding needed extra life and proper working order to the sump pump itself. I have had it now for 2 months, installed it myself and it was very easy to do (if you know what you are doing) and works problem free. I love the solid construction. Good buy for the money!
If you need a sump then the Zoeller M53 Mighty-mate submersible is what you want. I work in new construction and this pump goes in 99 out of 100 houses. I have never had a problem with it.
It pumps water from the sump with ease, March 25, 2014
By Scott T (Bellevue, WA) - I did a lot of research before I bought the Zoeller M53. This had the best reviews of all the pumps I looked at. So far it has been pumping the water from my underground sump with no problem. It pumps the water both quickly and quietly and is solidly built.
Well tonight I thought it was finally time to replace my sump pump (Zoeller M53) after 18 years! The float was sticking in the up position and it wasn't shutting off. Well after some messing with it the issue was a piece of debris stuck under the float so I moved it and now it's working fine. Don't go out and buy something from China from a local store, go with a Zoeller! Maybe it is time to replace it after 18 years but since it's working fine I think I'll just let it keep going! Really a quality product!
I just installed the M53 today and it is working great, no surprise. My review is really on my great previous experience with the M57, and I hope to get the same out of this one. The M57 is identical to the M53 in specifications.
The new M53 is running like a champ already right now, and I'm hoping to get another 15 years out of this one!
The M53 Switch needs to be replaced every 3 - 5 years depending upon how often the pump runs. It is very easy to replace the switch using a screw driver.
Check the rubber boot/seal where the float lever enters the pump cap assembly because it will harden over time. Keeping this lubricated with a bit of silicone grease will help prevent or solve this problem. Do not use a petroleum based grease. If the rubber/boot seal does fail the cap assembly will need to be replaced for around $30 - part #004703.
Check the impeller periodically. Just remove the base of the pump (they are several screws to remove) and to scrape/clear out any built up debris or buildup, clear the area by the exit pipe and make sure the check valve operates properly.
Remember to check the air hole in the disccharge pipe. It can get plugged. If it is blocked it can cause air lock and the pump will run but pump no water. The hold can be cleared with a small name.
Performing periodic maintenance for Zoeller sump pumps is not unique to Zoeller. All sump pumps require periodic maintenance. In fact, sump pumps with bottom screens or top suction may require more maintenance. Keeping the screen clean can be challenging.
Available parts for the M53 submersible sump pump includes the float switch (part-no: 004892). This is good because the motor is built to outlast the float switch. In fact a float switch should be replaced every two to five years depending upon how often the sump pump runs.
Replacing the Zoeller M53 float switch is a perfect solution to a failed sump pump switch. It makes sense to replace the switch rather than throw the pump away because of the following reasons.
