viscosity range for centrifugal pumps
viscosity range for centrifugal pumps
(OP)
hi everybody,
in our crude oil project, i am face with a oil with high viscosity ( viscosity= 120 CP). our Preference is usage of centrifugal pumps. could you please help me that is possible or not? do yo have any experiance to pump this viscose liquid with centrifugal pump?

at this regard i found that i can select a centrifugal pumps for this viscousity with consideration of correction factor.
thanks again.

120 cP could be, say, 150 cSt and probably above 650 SSU. To avoid higher viscosity levels due to cooling, it may be advisable to drain the pump when pumping is interrupted or when operating intermittently, and to keep the pump hot (at a proper temperature level) even when not working.

but i have two mor question:
1- correction factor calculation is on me or on manufacture? i mean that when i mantioned the viscosity in data sheet, whome shall check the correction factor? i think the vendor will consider it in their performance curve. am i right?
2- i select the BB1 or BB3 pump for this application ( crude oil: Q= 1000 m3/hr, H=360 m and viscosity is 120cp) do you recoomend this type of pump?

Can't help you on the pump question.

FWIW, have seen claims that BB1 pumps can develop the needed differential pressure. For example:

Again, contact an OEM - they will be glad to help.
