Pumps for Hot oil or thermal fluid.
Pumps for Hot oil or thermal fluid.
(OP)
I have used SIHI pumps for this application many times. I have now been offered a SALMSON pump.
The oil I am pumping is only at 200degC max. The pump curves for these two brands are almost identical as is their model numbers. The SIHI pump uses multiple lip seals bearing on a SS wear sleeve. The housing has cooling fins. The Salmson uses a mechanical seal which is separated from the main pump body by a finned housing also for cooling.
Has anyone had experience with the Salmson pumps for this application and are they reliable?
Thanks in advance.

Around here, we see SIHI, KSB, Allweiler, pretty much interchangeable.

For small hot oil pumps, we tend to use high temperature magdrives. They're costly, but they're compact, and since the thermal fluid is pretty clean, they tend to give many years of worry-free service with zero risk of leakage.

If flash point is < max operating temp, you may need to go for plan 52 double seals at the least.
