All lubrication points inside the centrifugal pump
Thread Content
I would like to ask the experts: where are the internal lubrication points of a centrifugal pump? Where are the sealing points again?
There are no lubrication points inside a centrifugal pump; if it has a mechanical seal, there are generally five sealing points.
There are no lubrication points inside the centrifugal pump; the mechanical seal consists of 1 pair of stationary rings and a seal between these stationary rings and their seats； 2-Seal between rotating and stationary rings ； 3-Sealing between the rotating ring and the shaft sleeve ； 4-Sealing between the sealed end cover and the machine body ； Sealing between the 5-axis sleeve and the shaft.
There are no lubrication points; there is sealed flushing instead
Additional note: a single-stage unit has only one sealing point; P
