The equipment consists of a sealed container (1) filled with a diathermic fluid (2), in which is immersed a volumetric pump (4) driven by an electric motor (3). The intake (5) and output (6) conduits of the pump are also wholly immersed, and the output conduit includes a flow reduction system. A second volumetric pump (24) is arranged within the container, such that its intake conduit (22) is directly connected to the output conduit of the first pump. The second pump is driven by a second electric motor (23). The second pump and motor are of reduced size compared to the first pump and motor, and are also wholly immersed in the diathermic fluid. The second pump has a second intake conduit (7) controlled by a valve (26) to allow operation independently of the first pump.
