Use Of Eccentric Reducer In Pump Suction Piping Enggcyclopedia The right pump suction pipe size is a compromise between cost (bigger pipes are more expensive) and excessive friction loss (small pipes cause high friction loss and will affect the pump performance). eccentric reducers installation. eccentric reducer is recommended for horizontal flow to the pump. An eccentric reducer is a type of pipe fitting used to connect pipes of different sizes. they are called "eccentric" because they are not symmetrical, with one side having a larger diameter than the other. in pump suction piping, eccentric reducers can be used to connect pipes of different sizes while maintaining the required fluid flow.
Use Of Eccentric Reducer In Pump Suction Piping Enggcyclopedia While eccentric reducers are primarily used in pump suction, they can be used in pump discharge if there are concerns about flow separation or non uniform velocity profiles. however, in most cases, concentric reducers are sufficient for discharge piping. Hence the need for the reducer at the pump suction. reducers have one unfortunate characteristic and that is that they have a built in high point or a built in low point or both depending on what you install. these high points can help in the accumulation of either bubbles of gas or slugs of liquid depending what you are pumping. Correspondence. abstract. eccentric reducers are traditionally recommended for the pump suction reducer fitting to allow for transportation of air through the fitting to the pump. the ability of a concentric reducer to provide an improved approach flow to the pump while still allowing air to be transported through the fitting is investigated. Suction reducer concentric and eccentric. for horizontal‑inlet pumps, the reducer at the pump should be eccentric, with the straight side up. this avoids the creation of a high point in the piping where gas can collect. for top‑inlet pumps, the reducer may be concentric or eccentric, as required to obtain clearance with the discharge piping.

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. Eccentric reducers with the flat side up are used for all pump suction lines (excluding pump handling slurry) on horizontal lines. this way one can avoid air getting trapped inside the pipeline during initial venting through the pump casing and will help in avoiding cavitation.
