The stainless steel eccentric reducer at the inlet of the centrifugal pump is generally installed with the top flat. However, when the stainless steel eccentric reducer is directly connected to an upwardly bent elbow, the bottom flat installation can be selected.
The reason why the stainless steel eccentric reducer is installed flat on the top is to prevent gas from accumulating in the eccentric reducer and entering the centrifugal pump, causing cavitation damage to the pump.
