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 Positive displacement pump technology
Highly configurable Dispense fluid your way
Unist’s proven positive-displacement
pump technology is at the center of the
Micro Pump™ system and is the driving
force behind its accuracy and reliability.

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.
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.
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.
Fluid Output Quantity
Choose up to 12 separate fluid outputs
