The part number 355020S is an exact replacement for the pump currently on my system. With this pump, what pump seals, etc. should I be replacing?

Hi, Brad. You will need to provide us with the pump housing model number or name in order for us to locate the seals needed. The motor # will not tell us.

You can use either the PL2853 or even the B853. You may also want to replace the seals using the GOKIT78.
