Why to use eccentric reducers in pump suction piping ...

If concentric reducers are used, their upper part can allow accumulation of trace amounts of air or vapors at the pump suction. This can lead to creation of bigger gas bubbles near the pump suction. If these gas bubbles manage to escape from the reducer and get into the pump suction, resulting cavitation is damaging for the pump.
