The invention relates to a pump assembly, especially of a mechanical seal assembly, for supplying a fluid, especially to a mechanical seal (), comprising exactly one drive () comprising a drive shaft (), a first axial pump (), which conveys the fluid in the axial direction (X-X) of the drive shaft, a second axial pump (), which conveys the fluid in the axial direction of the drive shaft, and a radial pump (), which conveys the fluid in the radial direction (R) of the drive shaft, wherein the first axial pump () and the second axial pump () are arranged in front of the radial pump () in the flow-through direction (B) of the fluid across the pump assembly, and wherein the drive () simultaneously drives the first axial pump (), the second axial pump () and the radial pump ().

The invention relates to a drive device () for water vehicles comprising a propeller (), a drive mechanism () for driving the propeller (), and a magnetic coupling () which is arranged between the propeller () and the drive mechanism (), wherein the magnetic coupling () comprises an outer magnetic element (), an inner magnetic element () and a can (), and wherein the can () is arranged between the inner magnetic element () and the outer magnetic element ().

Drive device for water vehicles

A magnet coupling system has driving and driven coupling elements, each of which has a magnetic element thereon between which a gap is defined through which a can passes. The magnet coupling system includes a sleeve bearing apparatus comprising a pair of axially spaced sleeve bearings. The sleeve bearing apparatus has a bearing casing enclosing both sleeve bearings and defines a closed fluid flow chamber through which a temperature-control fluid is circulated from an external source. An outer circumference of the bearing casing exchanges heat with an inner circumferential surface of the driven coupling element, and is accommodated substantially-completely within the driven coupling element, to heat or cool the sleeve bearing apparatus and the driven coupling element, and thus the gap between the magnet elements, to a suitable temperature.

An arrangement for concentrically positioning a first part relative to a second part, for example, a casing, or sleeve, (2) relative to a shaft (1), when the parts are made from materials with different coefficients of thermal expansion, provides a radial clearance (4) between the first and second parts. The first part (2) is supported along its length by portions facing radially away from the second part, at an abutment arrangement (7, 8) having the same or similar thermal expansion characteristics as the first part (2). The abutment arrangement (7, 8) is held concentric relative to the second part (1).
