In case diameter reductions are required it is recommended to use appropriate conical reductions possibly eccentric on suction side and concentric on discharge side and the distance from pump flanges must be equal or more than five diameters 5 3 3 Delivery Piping A foot valve and a cut off regulation valve are normally fitted on the discharge piping The foot valve protects the pump from possible backflow The cut off regulation valve excludes the pump from the line and adjusts output Never adjust flow rate using the valve on the suction pipe 5 3 4 Suction Piping The suction piping is very important for the correct operation of your pump UCN BL pumps are single stage centrifugal type and non self priming therefore the suction must be flooded at start up Also the suction line must provide sufficient pressure and smooth flow to pump inlet to prevent pump cavitation The suction piping must be as short and as direct as possible Elbows fittings or valves installed close to the suction can disrupt liquid flow and cause malfunctions If a long suction line is needed the diameter should be large enough to ensure low friction losses Air entrapment in the suction line because of leaks or improper design may cause the pump to lose prime and fail It is always necessary to install a foot valve in all those cases where the static height of the liquid is lower than the suction height of the pump The suction piping mu
