Piston Metering Systems

DOPAG piston pump metering and mixing systems feature a modular and customer-specific design. Therefore, different basic configurations are available with regard to the intended application and the requirements.

PRODUCTS

  • Ceradis
    Call for pricing
    Ceradis is used to handle low to high viscosity single component materials. They can be filled as well as abrasive. Just a suitable material supply and controller or metering computer are required. The material can be processed by either shot dispensing or continuous flow.

      Features and benefits

    High metering accuracy and repeatability, (� 1 % depending on the flow rate and material)
    High process security through monitoring the filling level
    No valve technology, no pneumatics
    Snuff back effect

  • Vectodis
    Call for pricing
    Vectodis is used to handle single component materials. Just a suitable material supply and metering computer is required. The modular construction of vectodis enables a wide range of use. This product line is especially recommended if a material needs to be applied in a high precision and repeatable way. The material can be processed by either shot dispensing or continuous flow.

      Application areas

    Bonding
    Sealing
    Moulding
    Encapsulation
    Shot dispensing
    Bead dispensing
    Control unit

    To control these systems a metering computer with touch screen terminal is used. With this metering computer all applications that can be achieved with vectodis can be parameterised and different metering processes can be memorised.

    The control unit is wired into a control cabinet. The metering computer can also handle applications where a speed proportional material supply is required, for example in combination with a robot.
