The resulting permissible forces have been determined according to The values are only applicable if the pump is bolted to a rigid and level foundation.
Secochem-Ex 5.3.5 Connecting the piping In addition to the general installation regulations, IEC 60079 (DIN VDE 0165) must be complied with. This regulation Never use the pump itself as an anchorage Caution stipulates overload protection by means of a motor protection point for the piping.

Secochem-Ex Operating the pump unit with a frequency inverter entails the risk of interference signals being emitted by the electrical connection cable, which may affect the environment. To eliminate such signals, shielded cables with concentric copper braiding must be used. Make sure that the shield ends have contact over a large area of the terminal compartments in the motor and the frequency inverter.
