2.2 Pumping media
WARNING
Vent dangerous gases and gas
mixtures safely. Do not expose
people to these gases.
WARNING
Do not use EXT555H pumps to
pump explosive gas mixtures as the
pumps are not suitable for this
purpose.
WARNING
On an Hi variant, gas pumped
through the interstage port will mix
with gas pumped through the pump
inlet. Ensure that the gases will not
react or combine to form dangerous
gases and substances.
Note: Concentrations of gases may be modified by
the compression of the pump.
CAUTION
Do not use an EXT555H pump to pump gases
containing more than 20% oxygen unless a bearing
purge is applied as stated in Section 2. If you do the
lubricant will be damaged and the pump will fail
prematurely.
CAUTION
Do not use the EXT555H pump to pump mercury
vapour, and do not allow mercury to come into
contact with the pump. If you do, the rotor may
corrode and fail.
