Why should I purchase the heavy duty seal?

The heavy duty shaft seal features carbon graphite, stainless steel, and Viton rubber. The properties of this seal contribute to the resistance of chemical corrosion. This is the best choice for salt chlorine generators or ozonators.

Hi, will this seal work with older 2002-2007 Northstar pumps? I have a model SP4015X20NS and would like to select this seal over the hayward seal because I use a salt chlorine generator and an ozonator. Thanks!

Hi Stefan, The correct Shaft Seal for your Northstar Pump 200-2007 will be the Seal Assembly (1998-2007) (SPX4000SA2).

My original pump seal failed.

Written on 6/7/2021 by Guest

My old pump seal failed and the new pump started leaking after operating for two weeks. I called INYO help desk and they sent out this extra heavy duty pump seal. I took the motor apart, disengaged the old seal and popped in the new seal. Everything worked like a charm and I am very pleased. Thank you INYO Help Desk!
