Here's my pool info:
Small in-ground gunite pool about 7,850 gallons
Pump is Anthony AR205-L
Pump motor is AO Smith K48K2P101, 1 HP, 1.25 Service Factor, Amps 12.6/6.3
Anthony Apollo DE filter 52 sq. ft.
Anthony pool heater
All old stuff but seems to be good quality.
The pump was leaking from the shaft seal, I think, since it was on that side of the seal plate. I replaced the shaft seal but it's still leaking a little. Took me a long time to get the motor off since it was frozen to the stud bolts, nuts came off fine. I'm not sure how long this has been in operation but probably since sometime in the 90's. I suspected it might not work since the motor shaft was slightly grooved, but I used emery cloth to smooth it out some and tried anyway but no luck. It's pumping now but it does not have the same flow as before. The impeller seemed fine and is not plugged and the skimmer and lint trap are clean. I was thinking the motor just may be worn out? I was going to replace the whole pump but I'm trying to save money at the moment and I'm not sure I want to try to do the plumbing connections. Do you guys think it would be worthwhile to just replace the motor? This seems like too big of a pump for the size of the pool but am I now stuck with replacing with the same HP motor that's in there now? I would like to go to a 2 speed motor but I'm trying to keep as inexpensive as possible for now and then when I replace the pump I can go with a 2 speed. Does voltage matching make any sense? There's a 3/4 HP AO Smith motor USQ1072 with voltage of 13.4/6.7 that is higher than my current motor. Any ideas or suggestions would be appreciated.
