The MEC 9000/11000/13500 pump is equipped with a system that
allows the flange to slide, which prevents breakage if foreign bodies
become lodged between the rotor and the pump body. (Except for
version G-GA)
To benefit from this system, it is important to follow these
instructions:
Before starting the pump, make sure the rotor has not dropped
down accidentally. This can be accomplished by making sure the
cut machined into flange lines up with the cut machined into pump
body.
