Abstract
Disclosed is a stirring device (D) including a screw shaft (1) driven by a drive unit, the screw shaft (1) being guided with respect to a body by way of a bearing, the stirring device furthermore including a seal (8) rigidly secured to the body and in contact with the ball joint (7) so as to ensure sealing with respect to the fluid to be stirred. The seal (8) is mounted on a seal holder (9), the seal holder (9) including a contact region (10) and being able to take up two positions, a first, operating position in which the seal (8) is in contact with the ball joint (7), and a second, maintenance position in which the contact region (10) is in contact with the ball joint (7).
