Safety precautions
► Keep disassembled magnetic couplings away from people with pacemakers.
– Minimum distance:
2 m
► Avoid convergence of the disassembled magnetic coupling components.
► Keep magnetized parts away from the magnetic coupling.
► Always keep a disassembled magnetic coupling away from computers, data carriers, and other
electronic components.
– The magnetic coupling can influence operational reliability of electrical and electronic devi-
ces.

2.7 Foreseeable improper use
Improper use of the product invalidates all warranty and liability claims. Improper use is any, even unin-
tended, use, which is contrary to the product purpose; and in particular:
● Pumping of corrosive media (exception: pumps in C-version)
● Pumping of radioactive media
● Pumping of gases that introduce an ignition source to the suction chamber
● Pumping of gases that contain impurities such as particles, dust, or condensate
● Pumping of media with a propensity to sublimation
● Pumping of fluids
● Use of the pump outside the specified area of application
● Use for pressure generation
● Use in strong electrical, magnetic, or electromagnetic fields
● Connection to pumps or equipment which are not suitable for this purpose according to their oper-
ating instructions
