Lubricant pump

A lubricant pump comprising:

• a reservoir unit with a reservoir housing in the form of a reservoir container for storing lubricant, the reservoir housing having a reservoir housing connection section;
• a pump unit with a pump device for conveying lubricant out of the reservoir unit to a lubricant consumer, the pump unit having a pump housing with a pump housing connection section;
• the pump unit and the reservoir unit being separably connectable to one another, the reservoir housing connection section and the pump housing connection section each having an opening which provides access to an interior of the respective housing, the openings being fluid-connected to one another such that lubricant can be transferred out of the reservoir unit into the pump unit when the housings are in the connected state;
• the lubricant pump also comprising:
• first and second plates on the pump housing connection section, which are movable such that the opening of the pump housing connection section is configured to be closed and opened with the first and second plates on the pump housing connection section, and/or
• first and second plates on the reservoir housing connection section, which are movable such that the opening of the reservoir housing connection section is configured to be closed and opened with the first and second plates on the reservoir housing connection section;
• wherein the movement takes place substantially perpendicularly to a transfer direction of the lubricant from the reservoir unit into the pump unit.
