A packing box (10) is provided for housing a packing seal (48) between a rotating shaft (32) and the casing (18) of a pump. The packing box (10) comprises walls defining an enclosed chamber for accomodating the packing. An annular plate (36) is provided between the pump housing (18) and the packing (48) in order to compress the packing against the shaft (32) in a direction essentially orthogonal to and away from the pump housing (18).
