2.5 Danger of ignition
WARNING: IGNITION HAZARD
Risk of injury or damage to the equipment. The pumps including the accessories are
not suitable for pumping combustible and explosive gases or vapours.
2.6 Hazards caused by noise
CAUTION: NOISE HAZARD
Risk of injury. The noise level produced by the pump is less than or equal to 60 dB(A).
Suitable hearing protection measures must be used while working.
2.7 Risk of damage to the pump
▪
Before starting up for the first time, the motor circuit must be equipped
with a suitable protective motor switch. Take note of the information in
these operating instructions and on the electric motor (wiring diagram).
▪
Do not allow the ingestion of small objects (screws, nuts, washers,
pieces of wire, etc.) through the inlet port. So always use the inlet
screen which is supplied as standard.
▪
Do not use the pump for applications that produce abrasive or
adhesive powders or condensable vapours that can leave adhesive or
high viscosity deposits. When planning to pump vapours other than
water vapour, contact our sales or service department for advice.
▪
This pump is suitable for pumping water vapour within the specified
water vapour tolerance limits.
▪
Avoid vapours that can condense into liquids when being compressed
inside the pump, if these substances exceed the vapour tolerance of
the pump.
▪
Before pumping vapours the pump must attain its operating
temperature. It takes approximately 30 minutes for the pump to attain
its operating temperature after the pump is started. During this
warming up phase, the pump must be separated from the process, for
example, by a blocking valve in the intake line.
▪
In the case of wet processes, we recommend the installation of liquid
separators upstream and downstream of the pump as well as the use
of the gas ballast.
▪
The exhaust line must be laid so that it slopes down and away from
the pump to prevent condensate from backstreaming into the pump.
▪
The entry of particles and fluids must be avoided under all
circumstances.
▪
Reactive or aggressive substances in the pump chamber may impair
the operating oil or modify it. In addition, such substances may be
incompatible with the materials of the pump (viton, grey cast iron,
aluminium, steel, resins, glass etc.).
▪
Corrosion, deposits and cracking of oil within the pump are not
allowed.
