I need a pump lesson please

[tphaggerty]

I have solar as well. I will have to check the head loss.

But, the Superpump (2 HP uprated) (again, this is not a Superpump 2, just a plain old Superpump) is just noisy, compared to many other pumps. The pump motor itself is whiny, with lots of harmonics, has been from day 1. The pump part doesn't really seem to make much noise. In any case, it is being replaced with a multi-speed motor. The Ikeric will run at low speed when the solar is not on, but kick up to a higher speed/higher pressure/higher flow when the solar kicks on in order to meet the higher head of the 2nd story solar. The Ikeric speed/head settings are adjustable, so they aren't actually set until everything is installed and running (unlike a regular 2 speed motor/pump, where high speed is normally something like 3300/rpm and low speed is 1650 hard set).

Anyway, the Ikeric (1.5 HP full rated) is supposed to be close to inaudible running on low speed and much quieter than the "average" pump when running at high speed, plus it is supposed to be much more energy efficient all around. Not installed yet, so I can't confirm.
