Pump assembly in particular supplied for mechanical seal assembly

The invention relates to a pump assembly in particular supplied for a mechanical seal assembly to supply a fluid. The pump assembly is used for supplying the fluid to the mechanical seal assembly (2a,2b), and comprises exactly one drive (11) comprising a drive shaft (24); a first axial pump (21) for conveying the fluid in the axial direction (X-X) of the drive shaft; a second axial pump (22) thatdelivers the fluid in the axial direction of the drive shaft; and a radial pump (23) that conveys the fluid in the radial direction (R) of the drive shaft, wherein the first axial pump (21) and the second axial pump (22) are arranged in front of the radial pump (23) in the flow direction (B) of fluid passing through the pump assembly, and the drive (11) simultaneously drives the first axial pump(21), the second axial pump (22) and the radial pump (23). 本发明涉及泵组件，特别是机械密封组件的泵组件，其用于供应流体，特别地，所述泵组件用于将流体供应到机械密封件(2a、2b)，所述泵组件包括：恰好一个驱动器(11)，其包括驱动轴(24)；第一轴向泵(21)，其在所述驱动轴的轴向(X-X)上输送流体；第二轴向泵(22)，其在所述驱动轴的轴向上输送流体；以及径向泵(23)，其在所述驱动轴的径
