I upgraded the single speed motor of my Hayward Tristar to a 2-speed motor but the new setup (in high speed) is not giving me the same amount of flow as the previous motor. This pump is for a waterfall feature and I'm not getting nearly the same flow rate.
Here are the details of what I changed:
Does anyone know what I may be missing?
Here are the details of what I changed:
- The wet end is the same and has not changed.
- The single speed was a Tristar Max-rate Pump with a 2.5 HP motor (SP3220Z1M) and 1.04 SF (2.6 Total HP).
- The new motor is a 2-speed full-rate 2HP (model SP3220Z2BE) with a SF of 1.35 (2.7 Total HP).
- I purchased an impeller (model SPX3220C) to go with the new motor. When I removed the existing impeller from the old motor, it was also an SPX3220C, the same exact impeller which I did not expect. According to the hayward manual (see link http://www.hayward-pool.com/pdf/manuals/TriStar.pdf), the impeller for the old motor should have been an SPX3220CM.
