Product details

Polaris R0734300 is the o-ring set with drain plug for the PB4SQ booster pump, the pump that supplies pressure to a Polaris pressure side cleaner.

What is in it

The kit brings the o-rings the PB4SQ uses at its sealing surfaces along with the drain plug. Because the rings are sized for this pump, there is no guessing at a hardware store assortment and no ring that almost fits.

When to use it

Fit the kit any time the pump comes apart, and specifically when water weeps at the housing seam or seeps from the drain. Seals harden with heat and chemistry and take a permanent set, so the ones coming out are rarely worth putting back. A leak that appears from behind the motor shaft instead is a shaft seal issue and needs a different part.

Questions and answers

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

Which pump is this kit for?
The Polaris PB4SQ booster pump, the pump that feeds a pressure side cleaner.
Does it include the drain plug?
Yes. R0734300 is the o-ring set together with the drain plug.
My booster pump is leaking. Will this fix it?
If the leak is at a sealing surface or the drain, yes. A leak coming from behind the motor shaft is a shaft seal problem and needs a different part.
Should I replace all the seals at once?
Yes. Once the pump is open, fitting the whole set costs little more than one ring and saves stripping it down again in a season.
