Vapor BLOCK !
Vapor BLOCK !
(OP)
Dear sir,
I am using Virtical inline pump (Sundye LMV-322) at 8200 rpm. It is used to transfer fluid that SG=0.6, Vapor Pressure =22.1 psia from 2psig to 310psig. Pump cannot run. I don't know why. At pump discharge we found only gas.what should I do? If you guys are expert, Do you know how to solve this problem?

RE: Vapor BLOCK !
Suction pressure you say is 2 psig (16.7 psia if you are at sea level) but the vapor pressure is 22.1. You are trying to pump a gas which is not possible with a centrifugal pump.
Check your numbers...
