3/4 Submersible Sump Pump Pumping Performance
3/4 HP Submersible Sump Pumps can handle large volumes of water. The amount of water ranges from 51 gallons per minute (GPM) to 84 gallons per minute (GPM) or 3,060 GPH to 5,040 GPH at a 10 foot vertical lift.
Can A 3/4 HP Sump Pump Handle Continuous Pumping Over Long Periods Of Time?
3/4 HP sump pumps are built to pump continuously for long periods of time. In case they do overheat the motor is thermally protected and will shut off if it gets too hot. Many 3/4 HP pumps have inside parts that are cast iron such as the shaft and impeller which also better support continuous pumping.
Pump Housing Recommended For 3/4 HP Sump Pump
The best housing is cast iron or bronze.
Cast Iron and bronze add significant weight to the pump which decreases the chances of the float getting caught on the side of the pit because the pump will not move as much when pumping heavily and continuously for long periods of time.
Cast iron and bronze are not likely to crack or warp under heavy continuous pumping. Both materials dissipate heat; cast iron dissipates heat the best.
Stainless steel is a third choice housing material.
Are Replacement Parts Available For 3/4 HP Sump Pumps?
Most 3/4 HP sump pumps have replacement parts available. Replacement parts are available because the housing material is built to last. The pumps cost more and generally the only thing that fails is the float/switch.
Can Some 1/2 HP Sump Pumps Pump As Much As A 3/4 HP Pump?
Zoeller 1/2 HP sump pumps can pump as much as the Ridgid, Flotec and Simer 3/4 HP sump pumps. The Zoeller pump motor is built with high efficiency and performance.
How To Prevent 3/4 HP Motor Short Cycling
If your pump runs even when it is raining, the pump will tend to short cycle if the float switch ON OFF points cannot be customized. That is, the pit will empty very fast and the pump will not run long. The best solution is to buy a non automatic sump pump and a separate float switch. The most dependable external float switch is the electronic HC6000 Switch controller. We live in a high water table area and our pump runs several times a day. We need a 3/4 HP to handle the water volume during heavy rainstorms. To prevent motor short cycling we installed the HC6000 in 2011. We have had no switch failures and are able to increase the distance between the ON and OFF point so the motor suns far less. Learn more about the HC6000 Electronic Switch.
