【Daily Question】12.1 Short Answer: What is the function of the check valve at the pump outlet? Prevent liquid from flowing back due to pump shutdown, reversal, or other reasons, so as to avoid debris flowing back and clogging the pump’s impeller.

The function of the check valve at the pump outlet is to prevent liquid from flowing back in the event of an unexpected shutdown of the pump, which could cause the pump to flip over and damage the motor.

To prevent backflow of water in the pipeline when the pump stops, which could cause the pump impeller to rotate in the reverse direction and become loose, as well as water hammer effects on the pump.

A check valve is installed on the outlet pipeline to prevent the pump from experiencing backflow of liquid due to some reason when the outlet valve is not closed; this backflow could cause the rotor to rotate in the opposite direction, leading to the loosening or falling off of components such as nuts on the rotor

Avoid backflow that causes the impeller to rotate in reverse.
