Quick overview
- Genuine Hayward Factory part SPX2707CM, the impeller fitted to the 1.0 HP Max-Flo II.
- Horsepower specific Impellers are matched to the motor rating, so the 1.0 HP part goes on a 1.0 HP pump and no other.
- Molded plastic The same plastic construction as the original impeller.
- Restores flow Worn vanes and a widened eye cost real head, which shows up as weak returns and a cleaner that will not climb.
- Check the diffuser too An impeller that has been running with debris through it usually leaves a scored diffuser behind, worth inspecting while the pump is open.
- Fresh seal recommended The mechanical seal comes off with the impeller, so plan on a new seal assembly at the same time.

Product details
The Hayward SPX2707CM is the genuine replacement impeller for the 1.0 HP Max-Flo II pool pump.
What the impeller does
The impeller is the spinning plastic wheel that actually moves the water. Its vanes throw water outward into the volute, and the shape of those vanes is what sets how much flow and head the pump produces at a given motor speed. Wear the vanes down, crack one, or pack the passages with hair and grit, and the pump keeps drawing the same power while delivering noticeably less water.
Matching the horsepower
Hayward matches impellers to motor ratings, and this is the 1.0 HP part. Read the horsepower off the motor label rather than going by what the pump was sold as, since motors get swapped over the years.
While the pump is apart
The mechanical seal comes off with the impeller and is not worth reusing, so fit a new seal assembly at the same time. It is also the right moment to look at the diffuser for scoring and at the seal plate for cracks.
