Why should I purchase the heavy duty seal?

Hi can you give me the dimensions of the two seals? I have an older Jandy Stealth JHPU 1.5HP pump, need to make sure it fits. Thanks...

A  Answered on 6/13/2015 by InyoPools Product Specialist Patrick P.

This is the correct shaft seal for an older Jandy Stealth JHPU pump. The white porcelain peice with rubber boot around it measures: 1-3/8" OD x 3/4" ID x 3/8" thick the spring parts measures 1-9/16" OD x 13/16" ID X 1-3/4" thick.

Will this seal fit in pump model SHPM 2.0 with serial # N08FD4672?

A  Answered on 4/4/2016 by InyoPools Product Specialist Scott W.

Good morning Tim,No that shaft seal won't work with that pump, the one you would need is part number 5020-087. Thanks Tim and have a great day.

Will this seal fit an older PHPU2.0 pump? I just got the motor replacement from you guys...and did not get the seal. Thanks -John

A  Answered on 4/3/2017 by InyoPools Product Specialist Lennox H.

Hi, John. Yes, this pump seal will fit the PHPU2.0 pump. I would also recommend getting the Diffuser O-Ring - R0558701 along with the Body Gasket  - R0555900.
