Basic Safety Instructions
2.1
General Information
Warning notices must be observed. Disregarding them may lead to damage to health and
property.
The diaphragm pumps must be operated by personnel who can detect impending dangers
and take action to prevent them from materialising.
The manufacturer or authorized workshops will only service or maintain the diaphragm
pump if it is accompanied by a fully completed damage report. Precise information about
the contamination (also negative information if required) and thorough cleaning of the
diaphragm pump are legally binding parts of the contract.
Contaminated diaphragm pumps and their individual parts must be disposed of in accor-
dance with the legal regulations.
The local regulations apply in foreign countries.
2.2
Electricity
Diaphragm pumps of operation mode S1 are supplied. When the location of operation mode
S1 devices is changed, please note that the testing must be repeated in accordance with
DIN EN 0105, DIN EN 0702 and
DGUV Regulation 3.
The local regulations apply in foreign
countries. Please note the following when connecting to the electrical power supply system:
The electrical power supply system must have a protective connector according to DIN
IEC 60364-4-41.
The protective connector must not have any breaks.
The connecting cable must not be damaged.
2.3
Mechanical Systems
Improper use can lead to injuries or material damage. Observe the following instructions:
Only operate the diaphragm pumps with hoses of the specified dimensions.
The absolute pressure generated at the pressure port must not exceed 1.5 bar!
Solid particles in the pumping medium impair the pumping action and can lead to dam-
age. Prevent solid particles penetrating into the pump.
Hazardous substances must be separated out as far as this is technically possible before
they reach the pump.
External mechanical stresses and vibrations must not be transmitted to the pump. Only
use flexible laboratory hoses or metal hoses for connecting diaphragm pumps.
Suitable securing devices must be fitted to the hose connections in order to prevent them
working loose.
In order to prevent danger arising when one or more diaphragms break, a suitable inert
gas is to be fed into the casing through the hose nipples on the front, the casing is to be
flushed during operation.
Inert gas is introduced through hose nipples attached to the casing. They must be flushed
and monitored during operation. A diaphragm rupture and the associated excessive out-
flow of pumping medium into the environment can be detected by monitoring the inert gas
flow in the inert gas outlet.
The pump must not be used to suck up fluids. Lay the exhaust pipe so that it slopes
downwards, so allowing condensate to flow out of the pump.
Collect the condensate and dispose of it in an environmentally compatible manner.
Maintain a space of least 50 cm between the pump and adjacent parts in order to enable
the pump to cool.
