![]() The best solution is to use an eccentric reducer orientated to eliminate the possibility of air pockets. A reducer fitting is typically used in pump suction piping to reduce the size of the suction pipe to match the size of the pump suction end flange. A reducer is a constriction and requires careful design to avoid both turbulence and the creation of pockets where air or vapour might collect. It’s standard practice to employ suction-side piping one or two sizes bigger than the pump inlet. Occasional damage on the discharge side due to liquid separation.Insufficient fluid pressure leading to cavitation. ![]() Noisy operation, turbulence and friction losses.If the design fails to produce a uniform velocity distribution profile at the pump inlet many pump problems and failures can be traced. The design of pump suction / inlet piping defines the resulting hydraulic conditions experienced at the pump inlet / impeller. ![]()
