9.1.1 Media to be pumped
• Dry and wet gases which are not explosive,
infl ammable, aggressive or toxic
• Air or air-steam mixtures
− which are free of solids
− which contain small amounts of light particulate
matters
9.1.2 Switching frequency
Th e max. switching frequency of 20 switching cycles per
hour should not be exceeded.
