Molten sulphur pump
Molten sulphur pump
(OP)
Hello guys,
which is the best API plan for a mechanical seal of a overhung single stage centrifugal pump which works with molten sulphur?
We are not sure of which is the best plan to use with a single mechanical seal.
If anybody has experience in sealing this product I would be very grateful of receiving some help about this issue.
Thank you so much,
Marc

Plan 02- for the seal chamber/seal. Your seal mfg should be able to design a seal with a jacketed gland plate- a gland plate with an annulus for steam and connectons in and out.
Plan 62- steam on the atmospheric side of the seal
Remember that you have to keep the sulfur within a certain temperature range to keep it in a liquid state. If I remember correctly, 275F is the lower limit.
A single rotating metal bellows seal is a good choice. This is a very difficult application.
I've heard of some Lewis pumps with a pair of bushings and a Nitrogen buffer- but I'm not convinced it works. Give them a call to see what they think.
