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 Vic, The Extra Heavy Duty 201 Pump Seal (PS3868) is the correct saltwater pump seal for your model pump.

Is the salt seal for the Hayward Super Pump and the Super Pump II the same? I just ordered a seal kit and it is for the Super Pump (square-ish shape) and I have the Super Pump II. Hoping I can use the one I now have and just not use the other parts in the kit. Returning would be time consuming for getting the pump running again. Thanks, Mark

Hi Mark G, The Hayward Super Pump and Super II Pump uses the same pump shaft seal and diffuser gasket.

Old system died

Written on 6/22/2018 by Guest

The hardest part of this install was working with how lazy the installer years ago was. There were no couplings so we had to cut the system free. We simply just took everything off the old system and put it right back on the new system.

Were these instructions helpful?
