What kind of cooler does the water pump use?

The parts that need to be cooled by the water pump are mainly bearings and mechanical seals.

For bearings: If the temperature of the pump is not high or the exposed environment is not high, it can be cooled naturally. If the medium temperature is high, air cooling or water cooling should be considered; If the ambient temperature is too high, water cooling or sliding bearing should be considered.

For mechanical seal, if its medium is clean and the temperature is not high, it can be cooled with its own medium; If its medium temperature is high, it can be cooled by external cooling medium; If there is no external cooling medium, it can be cooled by a cooler, the type is shell-and-tube type, and the minimum material is 304.
