For topinlet pumps, the reducer may be concentric or eccentric, as required to obtain clearance with the discharge piping. Enquire. Enquire. this is the question of pump suction line-eccentric reducer. This can lead (More on reducers and their implications mo-mentarily). Use eccentric reducers rather than concentric reducers at the pump suction. On the suction side, the diameter can be the same size, but oftentimes engineers select a size or two bigger, thus requiring an eccentric reducer. It is always a good idea to increase the size of the suction and discharge pipes at the pump nozzle in order to decrease the head loss from pipe friction. Put the flat on top when the fluid is coming from below or straight (see next Figure) and the flat on the bottom when the fluid is coming from the top. This will avoid an air pocket at the pump suction and allow air to be evacuated. As a general rule of thumb, suction pipe velocities should be kept below 2 m/s. Refer to NFPA 20 for the minimum system manifold size for each flow rating (GPM), but in no case should the system suction pipe be a smaller pipe size than that of the pump suction flange. Bigger nozzle would mean a bigger pump size, increasing not only the material costs but also the operating costs. Eccentric reducer in pump section pipeing minimized accumulation of any air or gas bubbles in the suction. No. Eccentric reducerThe reduction of the pipe size is achieved by decreasing the diameter of the fitting at a constant rate over a specified length, maintaining one side of the fitting horizontally (see Figure 1). Many pumps are manufactured with suction and discharge flanges of a different size than the suction and discharge sizes listed in Table 4.26(a), so the size must be adjusted accordingly, typically with eccentric or concentric reducers installed directly on the pump flange. Eccentric reducer (FSU) prevents vapor from being trapped and encouraging the phenomenon of cavitation which can further damage the pipe and pump impeller. You can easily avoid this unnecessary increase in cost by having pump nozzles smaller than the inlet / outlet piping and then using reducer and expander for flow continuity. The eccentric reducer on the pump suction reduces pump cavatation (pump catching air). In terms of diameter, discharge pipe diameter should normally match the discharge flange on the pump but can be larger to reduce friction losses and decrease system pressure. If the horizontal suction line carrying slurry inside then it is required to provide an eccentric reducer flat side down or flat side bottom type for smooth flow of slurry. eccentric reducer on pump discharge eccentric reducer on pump discharge.
