A centrifugal environmentally safe pump including a motor driven pump shaft having a fluid pumping impeller affixed thereto. A plurality of annular shaft supporting bearing assemblies are disposed along the shaft adjacent a lubrication chamber, the lubrication chamber housing lubrication fluid (e.g. oil) maintained at a level below rotating portions of the bearing assemblies so as to maintain a low operating temperature within the chamber and adjacent the bearings. A lubricating fluid dispenser having a thin-profile, disc-shaped portion is affixed to the pump shaft within the lubrication chamber for rotation along with the shaft. A plurality of wire-like fluid contacting members are loosely connected along the outer periphery of the disc-shaped portion through respective bearing sleeves, the wire members for dipping into the lubricating fluid when the pump shaft is rotating thereby dispersing or misting the fluid throughout the chamber.
