Yes the heat exchanger takes its feed from pump discharge and circulates back to pump suction.

Thank you all for your responses. Would this back pressure interrupt cooling water circulation towards the engine’s heat exchanger?

Hello dear engineers, Could a diesel engine be damaged severely because of back pressure due to non holding check valve? The diesel engine operates a fire water pump.
