Notes:

For sealing hot water pumps, the required leakage must always emerge in liquid form in order to lubricate the packing. The compression packing will have to be cooled via a lantern ring or a jacket, gland or shaft cooling system if the heat radiation via the stuffing box housing is not sufficient.
