3.3 Materials exposed to gases pumped
The materials and the components exposed to the gases in the pump are:
▪ Iron
▪ Aluminium alloy
▪ Steel
▪ Fluoroelastomer (seals)
▪ PFPE lubricant
3.4 Electrical data
If the pump is operang with a supply voltage below the nominal operang range,
example < 200 V in high voltage regions or < 100 V in low voltage regions, the product
will limit the maximum power deliverable to the pump motor. If the applicaon load
exceeds the maximum power available, pump rotaonal speed will be reduced. Refer to
Figure: Speed vs Power graph. At lower rotaonal speeds pumping performance will be
