What is the suction piping in centrifugal pump?
It is the induction pipe of a pump. The suction piping to the pump should be pressure charged or operated with a flooded suction to minimize cavitation of the drilling mud in the fluid end of the mud pump that can cause pressure pulsations. Why the suction piping should slope upwards from the liquid source to the centrifugal pump? The suction piping should slope upwards from the liquid source to the pump in order to avoid traps where air could accumulate. Air trapped in the suction reduces the cross-sectional area of the line and can cause the pump to cavitate – that is, to fail to get enough fluid in the casing for complete filling. Air drawn in through the suction piping can cause the pump to lose prime on start-up.
