Buying Guides
If you are thinking of changing your pool pump motor or are first-time buyers, the under-listed points are some of the critical features to consider before you make your ultimate decision:
Thermal Overload Protector
Adequate ventilation is crucial. A pump motor needs proper cleaning, continuously circulating air. Motors are usually heated at high temperatures. Therefore, we recommend that you look for thermal overload protection if your motor does not contain one.
Pump Size
A pump that is excessively huge for your pool will compel a lot of water through a small filtration system that is exceptionally compact, bringing about strain and opposition that will cause the pump motor to wear out and malfunction quickly than expected. It is consistently a smart thought to operate the pump at the most minimal stream rate expected to disperse your pool’s water within 8 hours.
Easy maintenance
If you have replaced your motor in the past, you should opt for a pump with Go-kit because that includes lubricants and gaskets, O-rings, shaft seals. There is a symbiotic relationship between the motor and the pump. If one has defects, the other one will also be affected, and if one is functioning well, the second one will also work well.
The flange
The square is the most popular frame type in the category of a pool pump motor. The square flange will be affixed to it and not the pump. There are mounting holes found at the corners of the flange called 56Y and 48Y frames. Some motors with 48Y frames are thru-style. Ensure that the square flange is attached to the motor and not on the part of the pump. If you’re not sure, detach the motor from the pump.
Threaded Shaft
A threaded shaft means the motor’s face will cling to the pump’s body, and the impeller is strung onto the motor shaft. These are known to be 56J frames. Also, the impeller can be tightened with a screw that is threaded into the shaft center. But if the exterior part of the shaft is unthreaded, that means it is a keyed frame and not threaded one.
