The rated flow rate of the centrifugal pump is 3 m³; why can it achieve a flow rate of 10 m³ when the outlet valve is fully open?

The rated flow rate of the centrifugal pump is 3 m³; the medium and operating conditions meet the requirements. Why can it deliver 10 m³ when the outlet valve is fully open? Will operating at 10 m³ for an extended period cause damage to the equipment?
Do you also need the outlet pressure? If so, then the pump was not selected properly
The outlet pressure remains at 0.3 MPa, unchanged
Look at the performance curve of this pump. If it is within the allowable operating range, with vibrations below 2.8 mm/s, a relatively low bearing temperature (below 50°C) that remains stable, continuous operation is possible; otherwise, it is not feasible.
The head of the pump is low, so its efficiency is relatively poor
That 3 cubic units isn’t the BEP point traffic
If it is the rated flow rate, an increase of over 10% is generally acceptable. A flow rate of 10 cubic meters per hour is a bit high. Also, has the motor power also exceeded the limit?
Power was indeed ignored, but after three hours of operation, the pressure and shaft temperature were all normal
The outlet pressure is also a factor; that means the pump chosen is too large
