I was wondering about the feasibility of something I once considered, as a workaround for lack of sufficient amperage for a 3/4 HP Goulds jet pump. What I noticed in a Grainger catalog was a high-efficiency 3/4 HP motor with the same current draw as a standard 1/2 HP, so it looked liked it would work on a 15 amp branch circuit without much risk of popping a breaker. I think it was a GE motor, and had the same service factor as a standard 3/4. Little possibility of upgrading the power to 20 or 30 amps.
The idea was to make a jet pump supply the same amount of water as the city-water supply did, which pointed to a 3/4 pump. I never did try the motor swap, since it turned out the city-water supply line was galvanized steel, which loses so much pressure at higher flows, that a 1/2 HP pump was the better match.
So I wonder, would the swap have worked, one 3/4 HP 56J 1.5 SF motor for another, even with the new one drawing current more in line with a standard 1/2 HP jet pump motor?
