Power Cord with 1 1/2 inch Discharge Port.Review Reveals Zoeller Model M57 1/3 HP Cast Iron Pump Is Durable. Consumers and Plumbers Rate It Highly.
The M57-001 Mighty Mate housing, volute, and impeller are cast iron. Cast iron provides heat dissipation to keep the motor cooler when running continuously and provides strength to the impeller as it spins around during heavy rainstorms. The vortex design keeps the impeller from clogging. A vortex design allow solids up to 1/2 (one-half) inch to flow through the impeller.
The M57 Submersible Sump also has a puncture proof float. The float is buoyant and made of solid polypropylene. Thus a puncture does not cause the float to fill with water and become inoperable.
In addition the motor operates on less RPMs (revolutions per minute) than many sump pumps. This reduces motor wear and provides higher pumping performance. Its pumping capacity as a 1/3 HP pump is equal to many competitors 1/2 HP pumps.
These are some of the reasons consumers and plumbers recommend the M57 Mighty Mate. Shop and Compare M57 with other models. Discover the quality and value of Model 57.
Well Built Mighty Mate M57
Pump Housing
The housing, volute (base) and impeller are cast iron and a higher grade than other pumps. It weighs twenty-eight pounds so will remain quite stationary during continuous pumping. Epoxy coating keeps the cast iron from rusting.
Pump Motor
The motor and housing are built as a unit therefore there is not an extra layer of material between the motor and outside housing. Competitors who buy canned motors from another source and slip them into their pump housing find the motor runs hotter during continuous pumping.
Buoyant Solid Float is Puncture Proof
The float is buoyant and made of solid polypropylene; therefore if it does get punctured it will not fill with water and fail to operate. The float itself is protected by a protruding stainless steel guard which protrudes from the switch box at the top. The guard keeps the float from touching the basin wall and getting hung up. The float is two pole – one at the bop and one at the bottom. The float does not move up and down on a rod so will not get stuck in the ‘on’ position.
Like all sump pumps the switch will eventually need to be replaced. Replacement is recommended every four to seven years depending upon the pumping frequency. Switches are easy to purchase online.
Pumping Performance Comparable To Many 1/2 HP
Zoeller motors are known for their efficiency. Since they rotate one-half as many times per minute as most competitors motors, the motor does not work as hard and thus lasts longer. Zoeller 1/3 HP pumps performance is equal to many competitors 1/2 HP pumps. Likewise the 1/2 HP pumps like M98 and M137 are known to have as much pumping capacity as a competitors 3/4 HP pump.
Clog Resistant Design
Zoeller does not use a screen to catch debris or small pebbles. Instead it uses a vortex impeller which allows solids up to one-half inch to flow through the impeller. This eliminates the need to periodically clean a screen.
Impeller Is Cast Iron
The cast iron impeller is extremely durable. Cast iron will handle continuous whirling during heavy rainstorms and not be impacted by small solids which may flow through. The volute is cast iron as well which adds additional durability and weight to the pump so it stays relatively stationary during heavy operation.
FAQ (Frequently Asked Questions)
What horse power do I need?
✔ Do you know how many inches of water flow into the basin in 30 seconds? If not, during a heavy rain, stick a ruler in the basin and see how many inches come into the pit during 30 seconds or 15 seconds or 60 seconds depending upon how fast the pit fills up.
To calculate how many gallons flow into the basin per minute (system capacity), measure the diameter of your sump pit, then take the number of inches the water rose on the ruler. For an 18 inch diameter pit, one inch of water equals to one gallon. For a 24 inch diameter pit, one inch of water is roughly two gallons.
If the water rose 8 inches in fifteen seconds in an eighteen inch pit, the pump would need to pump at a rate of 32 GPM. Eight inches in fifteen seconds is 32 inches in 60 seconds. Thirty-two inches in an eighteen inch diameter pit is 32 gallons of water. In this case the M57 would be an ideal sump pump for your needs.
Can M57 be used as an outdoor pump?
✔ Yes, the Zoeller M57 electrical mechanisms are waterproof. The pump is built for outdoor use. It is necessary to ensure the electrical outlets and connections into which the pump would be plugged are waterproof. can be used outdoors. Never use an extension cord.
Do I need to put a vent hole? If so, where should it go?
✔ A vent hole is recommended because it will reduce the amount of water pushing back on the pump.
✔ The hole should be below the basin lid and below the check valve. It can be even with the top of the pump.
Should the pump operate independently off a 15 amp breaker?
✔ Yes, Never plug two sump pumps into the same electrical socket. The fuse will blow. Do not use an extension cord either.
Will this pump fit into an 11 inch diameter pit that is not very deep?
✔ Yes. It will fit. The pump is 10 1/8 inches at the widest part. The pump discharge port is about two one-half inches from the bottom of the pump. The pump is about 10.3 inches high.

As with any sump pump the float switch will eventually need replacement. Unlike the built to throw away upon failure pumps, replacement float switches are available for the M57 and are easy to replace. If the sump pump will be used frequently it is a good idea to change it every three or four years. If the pump is not used much, the switch will probably last seven years or more.
