2 Safety
This chapter contains important information for safe operation of the pump.
2.1
Intended use
Pumping water-like fluids for industrial applications in batch mode.
2.2
Improper use
•
Pumping of unsuitable media or fluids, especially media which attack the diaphragm or other parts of the
pump. Consult the Material-and-Certification-Guide or contact Service if in doubt.
•
Operation outdoors and in private households.
•
Operation in in-vitro diagnostics.
•
Operation in explosion-protected areas.
2.3
Residual hazards
Observe the applicable accident prevention regulations and protection measures.
2.3.1 Pressure
The pump can be operated up to a maximum permissible pressure. The maximum permissible pressure
depends on the temperature of the fluid. The values for the maximum permissible pressure are specified in
the technical data and on the pump.
On exceeding the maximum permissible pressure, the diaphragm can burst and injure people.
•
Always maintain the maximum permissible pressure.
•
Make sure that the suction and pressure lines are adequately dimensioned and fastened.
•
Only apply pressure to the pump chamber when the the pump chamber is mounted on the drive.
2.3.2 Hot surfaces
The pump can deliver hot fluids. Strong and hot alkaline solutions are used for cleaning (CIP, SIP). These
can heat up parts of the pump and the lines (>72°C). There is a risk of burns when touching.
•
Do not touch the pump chamber when the pump is in operation.
•
Allow hot parts to cool down.
•
Keep the air vents and filter free. Make sure that heat can escape.
2.3.3 Fluid
The pump can deliver fluids which are toxic, caustic, aggressive or otherwise harmful to humans or the
environment. Strong and hot alkaline solutions are used for cleaning (CIP, SIP). There is a risk of serious
damage to health by contact.
•
Observe the safety data sheet of the fluid and wear the personal protective equipment and take the
safety precautions prescribed there.
•
Take preparations for possible leakages. When working on the pump, always behave as if there were
fluid in the pump.
•
Avoid chemical and biological reactions in the pump (mixing of different substances).
•
Avoid freezing of the fluid.
•
Avoid contact of corrosive media (e.g. NaCl; HCl) with the outer stainless steel surfaces of the pump
(e.g. shroud, base plate).
