The pump is running but not pumping any liquid.

Check to ensure the pump is installed correctly ie. The inflow is connected to the suction side, and outlet to the discharge side of the pump.Then ensure the pump has a flooded suction and that thewater supply valves are turned on. If the pump draws liquid from below the installation, thenensure the foot valve and strainer used is air tight and not disrupting suction lift.  If the pump is a new installation,then the pump will need to be bled through its bleed screw to remove any possible air locks.
