Vent dangerous gases and gas mixtures safely, do not expose people to these gases. If pumping
hazardous gases or vapours, observe the safety recommendations of the supplier of the gas/
vapour.
Do not use the nEXT pump to pump pyrophoric or explosive gas mixtures, as it is not suitable for
this purpose. The pump and its connections are not designed to contain an explosion.
In the interstage and booster versions of the nEXT pumps, 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.
Do not exceed the maximum continuous operating pressure. Doing so can result in dangerous rotor
temperatures and will shorten the life of the pump.
