thats your problem right there 750 gal per minute is INSANE!!!!!!!!!!!!!!!

all joking aside check your air outlet that is a noise maker and also maybe post a pic of how the water enters your sump i found that putting a fitting on the pipe JUST before it enters the sump so its skimming across the top helped with the noise so it wasnt falling 4 feet straight into water
