Impeller/casing gap
Impeller/casing gap
(OP)
Dear Forum,
I am checking some centrifugal pump's drawing and I need to know if the gap, between impeller OD and casing ID, is correct.
OD impeller 237 mm
ID casing 241 mm
Gap 2 mm
Flow 3600 l/min at 12 barg
4000 RPM
Could someone help me!
Thanks a lot

RE: Impeller/casing gap
From your description you are refering to the gap between the impeller OD where it discharges into the casing volute? If this is the case I would say that 2mm is a very small gap.
Or are you talking about wear-ring clearance?

It is a fire truck pump and here attach there is a section of.
