FIELD: non-displacement compressors and pumps.
SUBSTANCE: invention relates to a pump with an axial connector for movement of fluid medium. Pump has housing (2) with axial connector, which comprises lower part (21) and cover (22). Bottom part (21) has first sealing surface (212). Cover (22) has second sealing surface (222). Lower part (21) and cover (22) are made so that they can be attached to each other so that two sealing surfaces (212, 222) have direct contact with each other. At least one first seal groove (213) for receiving first sealing element is provided in sealing surfaces (212, 222), and at least second seal groove (214) is provided for receiving second sealing element. Slots (213, 214) are connected to each other through the connection area. In the connection area there is a resilient pre-loaded element which applies a pre-load on one of the two sealing elements.
EFFECT: invention is aimed at creation of pump with axial connector, in which reliable seal is provided, among other things, at connecting points between sealing elements for all operating conditions, including for long-term operation of pump.
