Page 7: Intended Use
SAFETY Intended use The eco-DUO330 dispenser is used to feed and precisely dose viscous materials. The dispenser is controlled using the eco-CONTROL EC200 DUO dosing control unit or the plug´n´mix dosing control unit. Check the chemical resistance of the materials that are in contact with the material before commissioning. -
Page 8: Personnel
SAFETY Personnel The operating organisation shall ensure that only appropriately qualified and authorised personnel work on this machine. It is responsible for ensuring that operators and maintenance staff possess the necessary qualifications. Personnel must be at least 15 years old. All personnel working with or on the machine must have read and understood this operation manual. -
Page 9: Preventing Damage To Equipment

Page 10: Residual Risks
SAFETY 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. -
Page 11: Transport And Storage
SAFETY 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 Pointed dosing needle Depending on its size, the dosing needle can be very thin and pointed. -
Page 12: Product Description
PRODUCT DESCRIPTION Product 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. -
