ABSTRACT:
A lubricant transfer device such as a lubricant metering device is provided that includes a lubricant dispenser that can use a standard replaceable lubricant storage cartridge as a lubricant source. The dispenser includes an adapter that is configured for mounting on a lubricant metering pump or the like and that can selectively receive the standard storage cartridge. The adapter permits the coupling of the storage cartridge to the pump so as to prevent unintended axial movement of the storage cartridge with respect to the pump and so as to provide an air-tight seal between the storage cartridge and the adapter, thereby permitting lubricant to be drawn out of the storage cartridge under negative pressure generated by operation of the pump. The adapter preferably includes an adapter body mounted over an inlet of the pump and a retaining ring that screws into the adapter body so as to clamp a bead, extending around a rim at the bottom axial end of the storage cartridge, between the retaining ring and the adapter body. A seal, preferably taking the form of an annular gasket compressed between the bottom end of the storage cartridge and an upwardly facing annular surface of the adapter body, prevents air from leaking past the adapter and into the storage cartridge. The storage container may additionally include a position indicator for providing an indication of the lubricant level within the storage cartridge.
