Is it possible for oil from a hot oil pump to mix into the water when there is no pressure in the circulating water?
Thread Content
I am not very familiar with the structure of the pump. If oil is found in the circulating water main during downtime, apart from a leak in the water cooler and a lack of pressure in the circulating water, is it possible for oil to enter the circulating water when the oil pressure inside the bottom pump is higher than that of the circulating water?
Note: Centrifugal pump, for transporting hot oil
Because water and oil do not come into direct contact, if oil is present in the water, it indicates that there is a leak somewhere, such as in the heat exchanger coils or the cooling water chamber of the pump cover
Agree with the view of 3983596_FPPZ.

Circulating water and the oil pumped by the pump do not come into contact.
