How does the operating point of the pump’s characteristic curve change when the actual resistance loss in the system is less than the head specified on the nameplate of the circulation pump?

When the actual resistance loss of the system is less than the head specified on the nameplate of the circulation pump, the flow rate at the pump’s operating point is greater, while the head is less than the parameters indicated on the pump’s nameplate.

As flow rate increases, head decreases and pump efficiency drops

When the actual resistance loss of the system is less than the head specified on the circulator pump’s nameplate, the flow rate at the pump’s operating point is greater than the head, which is in turn less than the parameters indicated on the pump’s nameplate.

1. Increased flow rate, 2. Decreased head, 3. Reduced pump efficiency.
