Risk of injury from bursting components and medium spraying out under high pressure
•
The maximum operating pressure must not be exceeded

Chap.
“Technical data" .
•
Observe and implement the recommendations in the

Chap.
“Installation in pipelines".
•
Protect the pump assembly against excess pressure. For example, the following safety devices can
be used:

a current limiter on the motor

a pressure relief valve

cut-off with a pressure switch

an overload coupling
Skin and eye irritation caused by auxiliary materials, operating materials and medium
•
Protective clothing (protective goggles, protective gloves) must be worn during all work involving
possible contact with auxiliary materials, operating materials and medium. In certain situations these
materials or the medium can enter the buffer chamber or gearbox.
•
Before opening covers, connectors etc., the pump assembly must be depressurised to prevent the
medium from spraying out.
•
To protect against fluids spraying out, carefully and slowly open the buffer chamber, the bearing cover
on the QD cover and the gearbox. Cover the valves or screws to be removed with a cloth or similar
item where appropriate.
Danger of burning or scalding
by auxiliary materials, operating materials and medium starting at 60°C
is present
•
when there is direct contact with hot auxiliary materials, operating materials and hot medium.
•
from spraying of hold auxiliary materials, operating materials and hot medium.
•
when there is inadvertent contact with hot surfaces (pump housing, pipelines).
Therefore
•
before maintenance and repair work, allow the pump to cool down, wear protective gloves and
protective goggles.
•
avoid touching the pump and the pipelines during operation.
Danger of burning due to exposed hot surfaces when the pump is running dry
Avoid pump dry running. Prevent the pump from running dry using, for example
•
a temperature monitor
•
a level gauge
•
a flow rate gauge
Automatic mode requires safety equipment
Rotary lobe pumps that are operated in automatic mode must be equipped with a temperature and pressure
monitoring unit (safety devices). These safety devices can be obtained from us as options.
