    Reliable Dispensing

    230 Micro Pump systems deliver fluid accurately with microliter precision for demanding dispensing scenarios. With modular components and plenty of options, each system is custom designed, guaranteeing it complements new and existing production lines.

    230 Micro Pump systems deliver reliable, consistent output thanks to Unist’s proven pump technology which displaces a set amount of fluid with each pump stroke regardless of changes in ambient temperature.

    • Precise output
      Regardless of temperature change
    • Reliable

    Maximize fluid savings and control when you customize a 230 Micro Pump™ to compliment your application.

    Your 230 Micro Pump system will be custom built for your application. Consider the 6 following choices and contact Unist today for a quote or for more information.


    CHOICE 1
    Continuous or Intermittent Fluid Output
    • Continuous Fluid Output - Choose the volumetric output and duration of a continuous flow of fluid.
    • Intermittent Fluid Output - Choose the volume of a single, intermittent ‘shot’ of fluid and a delivery rate up to 250 shots/min.
    CHOICE 2
    Pump Control Type
    • Direct Control – Each fluid output has its own pump and atomizing air control valves to be controlled by a machine controller.
    • Remote Control – Like direct control except each valve is mounted separately from the pump stack and connected with tubing.
    • Common Control – Groups of 1 to 6 fluid outputs are activated at the same time with a common control valve. Pump repeat timers such as the Pulse R digital timer can be used to repeatedly cycle the pumps in a group.
    CHOICE 3
    Fluid Output Quantity

    Choose up to 12 separate fluid outputs

    CHOICE 5
    Pump Output Type

    Pumps can be configured to deliver two types of output.

    • Fluid-only
    • Fluid/Air mixture (controlled with metering screw or external pressure regulator)
    CHOICE 6
    Fluid Supply
    • 16 oz. integral reservoir
    • 32 oz. integral reservoir
    • 64 oz. integral reservoir
