Heat transfer oil pump piping issues
Thread Content
Is it necessary to install reducers at the inlet and outlet of the hot oil pump in a heat transfer oil system? When a change in diameter is required, can the inlet pipe after the diameter change have the same diameter as the pump’s outlet pipe?
When installing a reducing pipe at the pump’s inlet, care must be taken to prevent air blockages. It is necessary to consider the relationship between the pump’s net positive suction head and the system’s net positive suction head, ensuring that the latter is greater than the former.
