ABSTRACT:
A pump drip collector is easily provided to a pump housing of a particular shape. A cylindrical drum of L-shaped cross section, incapable of serving as a drip collector by itself, is adapted to be freely pressed over a cylindrical protrusion from a flat face of the pump housing. When a circular end edge of the drum engages the face, it is spun welded in place. Thereafter, the drum and pump face together provide a complete drip collector. The drum may also pilot on the outside of the protrusion to maintain concentricity during the spinning process.
