CAUTION: HIGH PRESSURE IN PIPELINE
Risk of damage t
o the equipment. The systems connuously have maximum exhaust
line pressure limit. Operaon above the limit can damage the pumping mechanism.
The system has an exhaust pressure sensor which will give warnings and alarms when
the pump is operated for at least 20 seconds above the limits. The pump will
connue to run with a warning, however an alarm will cause the pump to stop. You
must provide an exhaust system with sucient conductance to make sure that the
exhaust pressure limit is not normally exceeded.
Do not reuse any O-ring or O-ring assembly and do not allow debris to get into the
system during installaon.
When you connect the system to the vacuum system, do the steps that follows:
▪ To get the best pumping speed use the minimum length of pipeline to connect the
vacuum system to the pumping system. Make sure that the internal diameter of
the pipe is not less than the diameter of the system inlet port.
▪ All components in the vacuum pipeline must have a maximum pressure rang
higher than the highest pressure that can be produced in the pumping system.
▪ Use exible pipelines in the vacuum pipeline to decrease the transmission of
vibraon and to prevent loading of coupling joints. We recommend to use the
braided exible pipelines.
▪ For T variants, make sure that the exhaust pipelines are rated for 130 °C at the
point of c
onnecon to the pump.
▪ For TX variants, make sure that the exhaust pipelines are rated for 160 °C at the
point of connecon to the pump.
▪ For all other variants, make sure that the exhaust pipelines are rated for 110 °C.
▪ We recommend the use of seals at joints where the connuous operang
temperature of the exhaust is higher than 160 °C.
▪ Give sucient support to the vacuum/exhaust pipelines to prevent the
transmission of stress to pipeline coupling joints.
▪ Use a pressure gauge in the inlet pipeline to make sure that the system operates
corr
ectly.
▪ The system inlet must be able to be isolated from the atmosphere and from the
vacuum system if corrosive chemicals are pumped.
▪ Install a check valve to the outlet of the system exhaust pipe to prevent the suck
back of exhaust vapours aer the system is shut down. The check valve also
provides addional reducon of the pulses in exhaust pressure.
▪ For dusty applicaons, use a low impedance inlet lter to limit the damage to the
pump.
