This is a sump pump, not a sewage pump like the M267 which handles waste water. If your pit has small pebbles or pieces of debris; however, the M63 can handle solids with a diameter of ½ inch.
M63 runs on 110-115V electric current and the motor turns at 1550 RPM (revolutions per minute). The RPM is lower than most one-third horse power sump pumps. Zoeller has built the motor to run at a lower RPM because the lower the RPM the longer the motor will last and only 80 percent capacity is used which also saves on the motor.
Will The Zoeller M63 Work In Your Basement?
Four factors determine if the Zoeller M63 will work in your basement. They are 1) The size of the pit 2) the vertical height of the discharge pipe 3) the amount of water entering the pit a minute or an hour 4) the length of the power cord will determine if the Zoeller M63 is the best sump pump for your water pumping needs.
The M63 measures 10-3/32 inches in width and 10-1/16 inches in height. Obviously it will fit very tight in a twelve inch diameter pit and may not won't fit because most basins narrow at the bottom so the bottom of the pit will measure less than 12 inches. The wider the basin, the better the fit.
Thought must also be given to installing a battery backup pump in the same pit. Fortunately the
Zoeller AquaNot 508 can be installed in line with the discharge pipe, that is to say the backup pump will sit in midair attached into the vertical discharge pipe above the primary pump. This eliminates the need for additional space.
The Zoeller M63 will function at a twelve foot vertical height easily. Going beyond fifteen vertical feet will decrease the amount of water that can be pumped in a minute or an hour during heavy rainstorms. The pump will still work but at a slower rate.
To find out how high the vertical height is, measure the inside height of the basin; then measure from the top of the basin to the top of the vertical discharge pipe where it joins the horizontal pipe that extends out from the basement. These two measurements give the vertical height. It is true that elbows in the discharge piping will slow the flow somewhat but if you have a standard setup with one 90 degree and two 45 degree elbows the resistance will not be increase too much.
The tested GPM (Gallons Pumped Per Minute) for M63 is 34 GPM (Gallons Per Minute) at a 10 foot vertical discharge pipe height or 2040 GPH (Gallons Per Hour). For a 12 foot vertical discharge pipe height it pumps 30 GPM or 1800 GPH. Obviously a lesser vertical height will yield a higher pumping GPM or GPH.
To know how much water enters the basin during a heavy rainstorm do the following steps.
- 1) Put a yardstick in the basin when the pump is not operating and determine the height of the water. The float switch is set to turn off when the water is less than three inches high on the float; however there is an additional height that must be added because the impeller must be sitting in water and the pump has a cast iron base height.
- 2) Measure the height of the water when the pump turns on. The float is set to turn on at 7-1/4 inches; however measure the total distance from the basin to the height of the water when the pump runs.
- 3) Measure the diameter of the basin. One inch of water height in an 18 inch diameter basin equals one gallon of water. In a 24 inch diameter basin one inch equals two gallons of water.
- 4) Count the number of times the pump turns on in 15 seconds.
- 5) Calculate the above. Let's say the water height in the basin is 5 inches when the pump is not running and 9 inches when the pump runs. So 9 - 5 is 4 inches of water is pumped every time the pump runs. If the pump runs 2 times during 15 seconds that is 8 times a minute. For a 18 inch diameter pit that is 4 x 8 x 1 = 32 gallons a minute. If the vertical discharge pipe height is 10 feet the Zoeller Sump Pump M63 can easily pump 32 gallons of water a minute continuously for a lengthy period of time and it is the best sump pump for your water pumping needs.
The power cord length is 10 feet. Using an extension cord is not recommended because of the motor draw.
We believe the Zoeller M63 is a great sump pump choice. If you thought the M53 was a great choice, you will certainly agree the M63 is definitely a good pump selection. Here's the enhanced features of the M63.
- -> 100 percent cast iron motor housing, pump housing, base and impeller,
- -> Electronically enhanced float switch tested to run over 3 million cycles.
- -> A 10 foot power cord.
- -> A Viton switch boot for extra switch seal from moisture.
- -> A led-lighted power plug to indicate the status of the circuit breaker.
- -> A 5 year warranty.
Zoeller Certainly Considers The Needs Of Its Consumers!
