seal plan change
(OP)
Hi all,
I am facing 1 issue regarding seal plan change. My issue is - I have 1 pump having service slop oil ( properties are below) in that pump I have only 53a seal plan. Water is used In this plan. Now I have to shift that pump At new location having new service - LSD liquid (properties are below). Now at new location water is not available so I can not use 53a seal plan. So please suggest can I use seal plan 11 and 76.??? If yes then why ? And if no than suggest any other seal plan in which water is not use.
Slop oil - Lsd liquid
Temp - 51 normal - 50 normal
Sp gr - 0.8539@ 51 degree c.- 1.012 @ 50degree c.
Vapor pressure- 0.63. - 0.13
Viscosity - 1.24 cp - 0.55 cp
Capacity- 5- rated. - 8.5 rated
Discharge pressure- 7.48. - 7.99
Suction pressure-2.66 max - 1.39 max
Existing pump having Arrangement 2 , 3CW-BB - 53A KN
Please suggest.
Thanks in advance.

RE: seal plan change
Is this new fluid susceptible to setting up or freezing at ambient temperatures?

Thank you very much for your reply... yes we can replace it with air cooler.
Sir, but i have 1 query regarding with solution. here my temp. is 50 degree. and if i try to cool by air then my air temp will be near around 38 or 40 degree. (Atm.) So is this temp. is sufficient to cool 50 degree.???
Thanks in advance.

2. Since Temperature is only 50 deg C, Barrier fluid temperature may not go above 70 deg C. if it is acceptable to you , it is not necessary to go for barrier fluid cooling.
3. Plan 76 is normally recommended for volatile liquid, therefore it should not be used in this case.
