Hayward SPX1707C Impeller - 3/4 HP

What This Part Is Used For
The Hayward SPX1707C is a 3/4 HP impeller used in compatible Hayward pump wet ends. It threads onto the motor shaft and is the main component that moves water from the strainer housing into the filter system. This part sits inside the pump housing behind the diffuser area.

Why This Part Matters
A worn impeller can cause low flow, weak skimming, and slow filter performance even when the basket is clean. Reduced circulation can also affect heater operation and chemical distribution. Replacing the correct impeller brings the pump back to normal output.

Installation and Fitment Guidance

Common Service Context
Techs typically replace this impeller when a pump is running but flow is noticeably down and suction-side checks look normal. It is also common during a wet end rebuild after a motor swap or leak repair.
