Abstract

A pump assembly is buoyant and includes an electrical drive motor (16), a centrifugal pump driven by the motor, and an assembly housing (2) accommodating the drive motor (16) and the centrifugal pump. Moreover, the pump assembly includes at least one inlet opening (8) which is arranged below the fluid surface (6) in the floating condition, and at least one outlet opening (10, 12). The assembly housing (2) is arranged such that on reaching a contact surface, the assembly housing changes its alignment with respect to the floating position.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a Section 371 of International Application No. PCT / EP2009 / 001261, filed Feb. 21, 2009, which was published in the English language on Sep. 11, 2009, under International Publication No. WO 2009 / 109305 A3 and the disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The present invention relates to a buoyant pump assembly, with the features specified in the preamble of the independent claim(s).[0003]Buoyant pumps, which, floating on the fluid surface of containers and waters, suck fluid or water from these containers and waters, are counted as belonging to the state of the art. The application of such pumps has been found to be problematic, if the containers or waters are formed in a closed manner, and the fluids to be sucked are intermingled with solid matter particles. The reason for this is due to the fact that these pumps sink into a region of the container or water which is close t...
