Then bleed all the air out manually (sometimes this requires hooking up a water hose to the system to give it a clean flush) and then test the system. If you can hear the circulator pump running I doubt it could be the problem but then it should be tested to make sure it is not.

Oct 08, 2019 · An example is shown below. The torque-speed curve is similar for all centrifugal pumps due to simple math: the pump torque varies as the square of its speed. However, when the pump is at rest—0% full load speed—the full load torque is never also 0%. Starting a rotating pump requires the motor to overcome the pump inertia and static friction.
