2.7 Residual risks
Thorough training, observance of the operation manual and compliance with safety
regulations are key to permanently accident-free operation.
The following residual risks may occur when operating this machine:
WARNING
Material hazardous to health
The conveyed material may contain constituents which are hazardous to health.
Such constituents may cause serious acute or chronic harm to health if they come into
contact with skin, are inhaled or swallowed.
• Always wear appropriate protective equipment
• Observe the specifications in the safety data sheet for the material
WARNING
Risk of injury from moving components
The machine is driven by an electrical drive unit. These generate very high forces.
Touching the components during operation may result in serious injuries.
• Do not operate the machine unless there is unrestricted visual contact with the moving
component
• There must be no persons or foreign objects in the danger area
WARNING
Pressurised material
Depending on the setting of the machine, the material is conveyed under very high
pressure. If the delivery rate is not adapted to the dosing needle being used,
unwanted spraying of the material might occur. This may result in serious injury.
Defective components can also cause spraying.
• Shut down the machine immediately
• The leak must be repaired by qualified maintenance staff before operation is re-started
SAFETY

11 / 32INST-002756 / A eco-PEN700 3D

• Relative air humidity less than 60 % (non-condensing)
• Uniform room climate
• Dry and free of dust
• No exposure to direct sunlight
• No aggressive, corrosive substances (solvents, acids, alkalis, salts, etc.) in the
environment
For storage always remove the stator and store separately (at 15–20 °C).
CAUTION
Splashing material
During initial commissioning and after being refilled, air bubbles in the material could
cause an uncontrollable spraying from the conveying area. This may result in injury.
• Always wear appropriate protective equipment
• Fully bleed the system before start of production
CAUTION

3Product description
The dispenser has been developed and tested for precision dosing of materials ranging from
low to high viscosity with extremely high repeat accuracy.
preeflow dispensers are positive displacement pumps. The conveying elements comprise a
rotating part, the "rotor", and a stationary part, the "stator". The rotor, which is in the form of
a type of knuckle thread, rotates inside the stator, which has one more thread turn and twice
the pitch length of the rotor. As a result, conveying areas are produced between the stator
and the rotor rotating inside the stator. The rotor also moves radially within the stator.
The conveying spaces move forward continuously due to the movement. The flexible shaft
used to drive the rotor compensates for the eccentric movement of the rotor and is completely
maintenance-free.
The sealing effect of the conveying elements of the dispenser is dependent on the viscosity
and pressure.
Since the direction of flow is reversible, the material can be sucked back to allow a clean
thread break.
The dispenser can be dismantled very quickly.
Together with the eco-CONTROL EC200 dosing control unit, the dispenser forms a dosing
system which is typically installed in a dosing station. The dosing control unit controls the
required parameters (e.g. dosing quantity, dosing speed, etc.).
