Product details

Pentair 71037 is the impeller locking screw used on EQ Series and Purex C Series commercial pool pumps. It is the genuine Pentair part.

What it does

The impeller threads onto the motor shaft and this screw is what keeps it there. It is a small fastener doing a serious job: if it backs out or fails, the impeller moves on the shaft under load and takes the seal plate and often the impeller itself with it.

When to fit a new one

Replace the screw any time the impeller comes off for a seal change or an impeller swap. Corrosion and repeated torquing both take the reliability out of the original, and on a commercial pump the cost of a fresh screw is not worth weighing against the downtime.

Questions and answers

What people ask about this product, answered by our pool techs.

What does this screw do?
It locks the impeller onto the motor shaft. Without it the impeller can work loose in service.
Which pumps does it fit?
Pentair EQ Series and Purex C Series commercial pumps. It is also listed under Pentair R Series commercial pump parts for the 5 to 15 HP range.
Should I replace the screw when I change the impeller?
It is good practice. A screw that has corroded or been over torqued will not hold reliably a second time, and it costs very little next to the impeller.
Is this a genuine Pentair part?
Yes. It is the Pentair OEM impeller locking screw, part number 71037.
