Suction Conditions
The suction and discharge system should be adequately insulated to ensure cleanliness and maintenance of the pump
when required. The suction piping should be as short as possible and have few bends. The pipe diameter should be
calculated for the minimum slurry velocity thereby reducing head losses, but keeping the velocity above the settling
velocity of the solid particles.
When the diameter of the suction pipe is larger than that of the pump flange, a reduction should be used whose shape
avoids the formation of air bubbles that then enter the pump.
