Safety Notices
Despite adhering to all applicable safety guidelines, some hazards remain which should be
taken note of for operation of the system:
General Safety
Informal safety measures
•
Always keep the operation and maintenance instructions with the dispense pump.
•
This is to be supplemented by the generally and locally applicable rules and regulations to
prevent accidents and for protection of the environment.
Operating environment, prevention of damage
In order to prevent damage and to ensure chambers required for precise dispensing are filled,
make sure that:
•
the dispense pump is never operated without medium (the stator will be destroyed),
•
the discharge side is not closed off during operation.
Appropriate use, warranty
The dispenser pump is intended to be used for the conveying and precise dispensing of media
in non-explosion-proof environments.
Check the chemical resistance of the parts in contact with the product before starting up the
unit for the first time. Refer to
Specifications
(pg 23).
Any of the following that are done without the explicit and written approval of the manufacturer:
•
conversions or additions,
•
the use of non-original spare parts,
•
repairs carried out by companies or persons that have not been authorized by the manu-
facturer
can lead to the warranty being rendered null and void. The manufacturer shall have no lia-
bility whatsoever for damage resulting from failure to follow the
Operations
(pg 8) and
Maintenance
(pg 12) instructions.
CAUTION:
Very high pressures can be produced, depending on the viscosity and speed of
rotation, and this could result in unintended spurting of medium.
Check the flow quantity in
relation to the dispensing needle used
.
CAUTION:
For initial start up and after being refilled, air bubbles in the medium could cause
an uncontrollable spurting from the outlet nozzle. Only start production operation once the dis-
pense pump has been completely bled.
CAUTION:
Wear suitable protective clothing if chemical, corrosive, or dangerous
products are to be used.
Note and comply with the safety stipulations and the
information from the manufacturer.
Ensure sufficient bleeding or extraction of air.
Take special safety precautions if working with dangerous media; for example, pro-
vide eye flushing facilities if working with corrosive chemicals.
CAUTION:
Preparation before starting up - visual check.
Make a daily visual check of the
dispense pump before starting work and before each shift change. If there is any doubt that the
unit is not perfectly ready for operation, it must be shut down at once and inspected by a suit-
ably qualified person before it used again.
