Title (EN) SYSTEMS AND METHODS OF SECURING A COMPLIANT MEMBER IN A PUMP
(FR) SYSTÈMES ET PROCÉDÉS DE FIXATION D'UN ÉLÉMENT SOUPLE DANS UNE POMPE
Abstract:
(EN) A pump includes a pump-head portion including a pump body and a magnet cup. The pump body defines an inlet and an outlet, and the pump body and the magnet cup together define a pump cavity. The pump includes a suction shoe situated on the pump body. The suction shoe includes an engaging portion. The pump includes a movable pumping member situated in the pump cavity and at least partially received within the suction shoe. The pump includes a permanent magnet situated in the magnet cup, and coupled to the pumping member. The pump includes a pump-driver portion including a magnet driver located outside the magnet cup. The pump includes a pressure-absorbing member situated in the pump cavity. The pressure-absorbing member is configured to engage the engaging portion of the suction shoe such that the suction shoe can move relative to the pressure-absorbing member within a predetermined range of motion.
(FR) La présente invention concerne une pompe comprenant une partie tête de pompe comprenant un corps de pompe et une coupelle d'aimant. Le corps de pompe définit une entrée et une sortie, et le corps de pompe et la coupelle d'aimant définissent ensemble une cavité de pompe. La pompe comprend un sabot d'aspiration situé sur le corps de pompe. Le sabot d'aspiration comprend une partie de mise en prise. La pompe comprend un élément de pompage mobile situé dans la cavité de pompe et au moins partiellement reçu à l'intérieur du sabot d'aspiration. La pompe comprend un aimant permanent situé dans la coupelle d'aimant, et accouplé à l'élément de pompage. La pompe comprend une partie entraînement de pompe comprenant un pilote d'aimant situé à l'extérieur de la coupelle d'aimant. La pompe comprend un élément d'absorption de pression situé dans la cavité de pompe. L'élément d'absorption de pression est conçu pour venir en prise avec la partie de mise en prise du sabot d'aspiration de telle sorte que le sabot d'aspiration peut se déplacer par rapport à l'élément d'absorption de pression dans une plage de mouvement prédéterminée.
