• a pumping system (5) placed in the pumping compartment (4) or according to a particular embodiment outside the water, ensures the transfer of water from the filtration zone (1) to the water room to be filtered (6)
• the pumping system (5) includes two pumps of different power operating alternately
• the most powerful pump (5a) draws water into the pumping compartment (4) and transfers it to the piece of water to be filtered (6)
