3.33-phase pump
The 3-phase dir
ect-on-line pump includes a customer interface, electric
terminal box and an embedded 3-phase electric motor. The electric terminal
box provides a method for connecting and conguring the 3-phase supply
to the embedded 3-phase motor. The electric terminal box also provides the
user interface, comprising of:
▪ 3-Phase power input eld wiring terminals and cable gland▪
▪ Hours counter (This contains a compact lithium cell battery which▪
contains 1,2 DimethoxyEthane, included in the REACH candidate list
of substances of very high concern, in the electrolyte.)
3.4Gas ballast control
To pump high vapour loads, gas ballast can be delivered into the pump to
prevent condensation of the vapour carried by the pumped gases.
Air can be introduced to the low vacuum stages through the gas
