What happens if the pump is operating too far to the right on the curve?

When a pump operates too far to the right on the curve, this simply means that the pump is delivering a flow rate greater than that for which it was designed. In other words: The pump is too small for the volume flow needed by the system. Operating the pump in this range may cause damage to the pump and the motor.

The pump must always be operated within the lower and upper flow rate bounds. Ideally, the pump should be operated as close as possible to the point of optimal efficiency in order to ensure a long service life and in order to minimise energy consumption.
