Eccentric reducer on pump suction
WebA reducer is a constriction and requires careful design to avoid both turbulence and the creation of pockets where air or vapour might collect. The best solution is to use an eccentric reducer orientated to eliminate the possibility of air pockets. As a general rule of thumb, suction pipe velocities should be kept below 2 m/s. WebWhen the suction piping is in a horizontal plane, we should provide a minimum of “three to five times the diameter of the suction nozzle” straight pipe length between the pump suction nozzle and the first elbow or a …
