Design eccentricity of pump impeller
Design eccentricity of pump impeller
(OP)
I am designing footings for several slurry pumps. I know that I should be able to calculate dynamic loads from
Fo=m.e.w^2 where
m=impeller mass, e=eccentricity, w=angular speed in radians/sec
Does any have any good references for eccentricity of slurry pump impellers? Both initial and after several years of service. Trying to get information from pump manufacturers is like pulling teeth from a canary.

2. As to the amount of eccentricity after a number of years of slurry pumping is like asking for the winning lottery number -- how would you expect the manufacturer to have this knowledge as there are innumerable factors acting on the wear characteristics of an impeller.
As a matter of interest what size are these slurry pumps?

I would expect eccentricity to be small at time of installation but what could I expect in service as a worst design case? How bad could it get before the pump was shut down?

or check in Google - "Pump vibration" many references.
