Abstract
A cooling water pump, for an internal-combustion engine in particular, with a casing provided with at least one bearing designed to support a pump shaft, with a sealing element devised to seal the bearing against a working space containing the cooling agent as well as with a leakage chamber arranged in the casing and receiving the cooling agent that leaks through the sealing element. A particularly simple way of production is achieved by the fact that the leakage chamber may be brought out of shape by a slider pulled in an essentially transverse direction and preferably normal to the plane on the axis of the pump shaft.
