Eccentric reducers are used at the suction side of pumps to ensure air does not accumulate in the pipe. The gradual accumulation of air in a concentric reducer could result in a large bubble that could eventually cause the pump to stall or cause cavitation when drawn into the pump.

An eccentric reducer is a type of pipe fitting used in plumbing and piping systems. It is designed to connect two pipes of different diameters, allowing for a gradual transition in size. Unlike concentric reducers, which maintain a consistent centerline, eccentric reducers have one end with a smaller diameter and another end with a larger diameter, creating an offset or eccentricity in the centerline. This design is particularly useful in situations where the pipes need to connect at different heights or levels, and it helps prevent the accumulation of air or gas pockets in the pipeline.

Flow Control: They are used to control the flow of liquids or gases in pipelines. By gradually reducing or increasing the pipe diameter, they help maintain the desired flow rate and reduce turbulence, pressure drops, and wear and tear on the system.

Compensation for Pipe Misalignment: Eccentric reducers can compensate for pipe misalignment or differences in elevation between two connecting pipes. This helps ensure a smooth and efficient flow of fluids while avoiding issues like backflow or blockages.

Air or Gas Removal: The eccentricity in the reducer design can prevent the buildup of air or gas pockets in the pipeline. This is particularly important in systems where the complete drainage of the pipeline is necessary.

Installation Flexibility: Eccentric reducers are versatile and can be used in various plumbing and industrial applications where pipes need to transition from one size to another while accommodating specific installation requirements.

Eccentric reducers are available in a range of materials, including stainless steel, carbon steel, PVC, and other materials, to suit different applications and industries. Proper selection and installation of eccentric reducers are crucial to maintaining the integrity and efficiency of piping systems, as they play a key role in controlling fluid flow and preventing issues such as pressure fluctuations and air entrapment.

An eccentric pipe reducer is installed with a straight side up so that the air trapping can be prevented at the pump station.

Eccentric reducers are highly used with a flat side up in the pump suction to avoid cavitation. They are also used in keeping the small and big size pipes together for reducing the vibrations or noise at the same time.

It does not require much installation space. But you must ensure proper installation of the reducer in pump suction piping to reduce the accumulation of any gas or air bubbles in the suction.

If the gas bubbles manage to outflow from the Eccentric reducer and get accumulated in pump suction, it will result in cavitation which will damage the pump. But if they stay trapped in the reducer only, they will reduce the existing cross-sectional area of the pipe for the liquid to flow. This may result in higher liquid velocity into the pump suction, which can increase the frictional losses. Not only this, but it will also affect the long term reliability and overall performance of the pump.
