Abstract
An immersion motor includes a housing (3) having a wall (4) with a watertight cable penetration (5, 6; 5, 6′). The cable penetration includes an inlet (5) in the wall (4) for a cable (25) and a sealing collar (6; 6′) that can be released from the inlet (5) having a penetration (20) for the cable (25). The sealing collar (6; 6′) includes a first seal (45; 45′) disposed on the penetration (20) and means for applying force (75, 85, 90) to the first seal (45; 45′), which is designed for permanently applying force to the first seal (45; 45′) radially in the penetration (20). The cable penetration (5, 6; 5, 6′) further includes means for releasably attaching (35, 40) the sealing collar (6; 6′) to the inlet (5). At least one second seal (120, 125) is provided between the sealing collar (6; 6′) and the inlet (5).
