High pressure CASING, low flow/head pumps?
High pressure CASING, low flow/head pumps?
(OP)
I've got a unique application; a cooling loop that has to run at 900 psig, but the pump only needs 100 gpm and 115' TDH. Water is at room temps (say 65 F.).
So the casing and seals on the pump need to be rated to ANSI 600 conditions or better, but the flow rate puts it well above most high pressure pumps I've found. I would think there are some utility boiler circulators in this range, but darned if I can find them.
Know any vendors who cover this range? Thanks in advance!

I'll check those vendors, thanks!

clarification is needed on TDH . . .
the original post/request stated:
"a cooling loop that has to run at 900 psig, but the pump only needs 100 gpm and 115' TDH. Water is at room temps (say 65 F.)."
then you state:
"I didn't go into it, but at the moment they are using an atmospheric tank as the suction source; this means the pump has to produce 900 psi from basically 15' suction head."
without doing the calcs, the TDH is helluva more than 115' from 15' suction to 900 psig discharge. 900 psig is roughly 2100'; so TDH is slightly less.
please clarify actual/design conditions so reasonable results are obtained.
thanks!
