Preventing damage to equipment
In order to prevent damage to equipment and to ensure precision dosing, note that
• the dispenser must never be operated without material (the stator will be destroyed)
• the material inlet (feed) and the material outlet must never be closed during operation
• the material outlet (e.g. dosing needle or mixer) must not be damaged or blocked
• the dispenser is operated with a positive feed (inlet pressure)
• there is adequate inlet pressure when conveying highly viscous material
• when pumping without a positive feed (inlet pressure), no dry running or cavitation of the
dispenser occurs
• the direction of rotation of the drive is always the same as the direction of flow of the
dispenser
• the specifications in the product data sheet for the material are observed and adhered to

Organisational safety measures
The necessary personal protective equipment must be provided by the operating
organisation. Personal protective equipment must be worn when carrying out all work and
procedures.
To ensure the provision of suitable personal protective equipment, the safety data sheet for
the conveyed material must be observed. Specifications for e.g. cleaning products and
lubricants must also be checked and observed.
All personal protective equipment must be checked to ensure it is working properly before
starting work.
