<p>A filtration unit for a swimming pool, which delivers a jet of water after cleaning, has an inverted L-shaped housing with the vertical leg containing the filter (6) with the jet nozzle (7) extending from it, has this portion immersed in the water. The horizontal portion has a chamber (14) housing the pump (5) alongside a chamber (13) housing the motor (2) and a seeling partition (12) between them. The motor spindle (4) passes through a seal (18) mounted in the portion. The latter is formed by the end of the motor housing and forms a completely watertight barrier also preventing steam from passing through. An electrically insulating coupling (4, 21) is included between the pump (17) and motor spindles. The motor is mounted on insulating blocks (27, 28).</p> |
