Abstract: A pump with a wear ring includes at least one impeller; at least one diffuser; and at least one wear ring positioned between the at least one impeller and the at least one diffuser. The wear ring is removably coupled to the diffuser and includes radially extending clutch members. The clutch members are configured to hold a portion of the at least one diffuser.

Abstract: An ignition switch and steering lock device for motor vehicles, comprising: a main body; an electronic control circuit provided with input/output interfaces; a locking mechanism; a mechanical actuator, for moving the locking mechanism. The locking mechanism is mobile between a locked position in which its action blocks the vehicle steering in a fixed orientation relative to the frame, and an unlocked position in which the elements do not block the rotation of the steering relative to the frame. The locking mechanism can be moved into the locked position only at a minimum steering lock orientation. The device further comprises at least one unlocked position sensor to determine the position of the locking mechanism and at least one steering orientation sensor to determine the orientation of the steering.

Abstract: An ignition switch and steering lock device for motor vehicles, comprising: a main body; an electronic control circuit provided with input/output interfaces; means for locking; a mechanical actuator, for moving the means for locking. The means for locking are mobile between a locked position in which their action blocks the vehicle steering in a fixed orientation relative to the frame, and an unlocked position in which said elements do not block the rotation of the steering relative to the frame. The means for locking can be moved into the locked position only at a minimum steering lock orientation. The device further comprises at least one unlocked position sensor to determine the position of the means for locking and at least one steering orientation sensor to determine the orientation of the steering.
