Eccentric reducer position at a pump
Eccentric reducer position at a pump
(OP)
I have a problem. I know that top-flat position of a eccentric reducer is used at a pump suction when the pump is pulling water from a sump. However, I don't know which position of a reducer is correct between top-flat and bottom-flat when a pump is pulling water from a high level, higher than pump, vessel at a suction side.
I highly appreciate if anyone helps me.

It seems to me that we engineers are more comfortable in maintaining status quo as far as this issue is concerned.

However, I have seen many trouble-free installations where the flat side was down - but for convention sake and peace of mind, I would always put the flat side up - unless there was a very good reason not to do so.
