Eccentric Reducer An eccentric pipe reducer fitting is manufactured with the smaller outlet off center to the larger end, which allows it to align with only one side of the inlet. The reducer must be installed with straight side up so that it can prevent trapping air at the pump suction. The eccentric pipe reducers allow simple connection of different sized pipes. Uses of eccentric reducers:
Keeping big pipes and small pipes together.
Reducing noise and vibration at the same time.
Requires less installation space.
Absorbs pipe wall and fluid borne noise.
Less turbulence or material entrapment.
Eccentric reducer are used with flat side up in pump suction to avoid cavitation.
