7. idable consideration should be given to over sizing the suction line to reduce suction losses On suction lifts a foot valve will be required sized equal to the suction line size For applications on creek beds or dams please install a foot valve amp strainer well submerged below the surface to reduce whirlpools amp air inclusion Air inclusion can result in cavitation reducing the pump performance amp eventually destroying the pump or its components If bends are required long radius bends should be used To help ensure a less turbulent entry into the pump a Straight length of pipe should be installed between any bends and the pump inlet This straight length should be at least 2 5 times the pump inlet diameter in length Pipework supports should be installed to both inlet and outlet pipes to ensure that they are supported independently of the pump flanges DISCHARGE PIPING Typizel Arrangement Discharge piping must be selected of a size that would equal the discharge of the pump For long discharge lengths consideration should be given to using larger diameter pipework Larger size pipes have lower pressure losses for a given flow rate and may help reduce the running costs for your pumping system Talk to your nearest Davey dealer to calculate all system losses To avoid air pockets in discharge lines at high points vent cocks may be required to release air blocks accumulated within the system Air pockets may affect
