centrifugal pump for viscous fluids
centrifugal pump for viscous fluids
(OP)
Currently we are using a positive displacement pump (gear pump) in order to pump viscous oils. We have got some problems with pulsation during pressure drop measurements, which needs to be very accurate, therefore we are investigating whether it is possible to use a different more smoothly running pump type.
The oil has a Newtonian viscosity range of up to 200cp.
Is it possible to use centrifugal pumps for this kind of viscosity? If yes does someone know suppliers (UK).
Maximum flow would be about 4000l/hr. Maximum pressure drop would be about 8 bar.

On the other hand, you might consider a small 3 screw pump, they tend to run smoothly, and can handle ranges of viscosity with little change in delivered flow rate.
Something like the IMO series of pumps. They're very good for applications like this.

25 mm discharge dia.
250 mm impeller dia.
A fairly standard pump size from a number of manufacturers.

I specifically looked at the Goulds model IC, because that's what I had available data on at the time, but anybody with a DIN standard pump will have something similar.

Try the Moyno vertical pump. It specially works well with viscous fluid. Here is the link for your information.
