The photo is of a Pentair Variable Speed Pump Motor for residential use. This has been the USA requirement for swimming pools for about 15 years now as the old, loud, single speed pumps are obsolete. The new variable speed has different speeds that pump motor can operate to save on electricity. No pool needs to run for hours on end at high speed filtering the system. It can run on low speed and get the job just as well. Therefore, the only pumps available now are variable speed. They are around the $2000 each range.
