The invention is directed to a bulk materials pump and its use. The pump comprises a housing having a flow path for bulk materials located between an inlet and an outlet of said housing, wherein said flow path in said housing is further defined by a space between two rotatable drive disks spaced from each other and wherein a materials scraper is present between said drive disks at the outlet to avoid materials being transported between said drive disks back to the inlet.
