When starting a conventional centrifugal pump, the outlet valve must be ( ) . The reason for this is that, according to the pump’s performance curve, ( ), which helps to properly protect the motor and also prevents hydraulic shock in the outlet pipeline. Answer: Turn off. The starting power is lowest when the flow rate is 0.

When starting a conventional centrifugal pump, the outlet valve must be (closed). This is because, according to the pump’s performance curve, (the starting power is lowest when the flow rate is 0), which helps to protect the motor effectively and also prevents hydraulic shock in the outlet pipeline.

Turn off; the starting power is minimal when the flow rate is 0
Turn off – the current is highest when the pump starts
Close. When the flow rate is 0, the starting power is at its minimum
