preeflow® eco-PEN XS Precision Volumetric Dosing Pump, for Repeatable Micro Dispensing
About preeflow® eco-PEN XS Precision Volumetric Dosing Pump, for Repeatable Micro Dispensing
The preeflow eco-PEN XS is a precision volumetric, positive displacement, dosing/dispensing system capable of dispensing nano and microliter quanities of material accurately and repeatably. eco-PEN technology is based on the well established and proven preeflow progressive cavity pump principle, which enables true volumetric dispensing that is viscosity independent. The technology can dispense of a wide range of viscosities, from water-like substances up to thick pastes, including filled materials like solder paste, with low shear and no dripping.
The eco-PEN XS is suitable for both line and dot dispensing, with bead widths starting from >0.1 mm, and an adjustable dispensing rate to suit the run speed. With accuracy of ±1%, >99% of the time, the device gives electronics and medical device assembly application specialists a reliable, repeatable tool for dispensing small liquid volumes.
The preeflow eco-PEN XS can be easily integrated into any of our robotic dispensing systems or other automation. Its lightweight design, weighing approximately 175 g, enables its use in high speed robotics, and the cartridge design means that several eco-PENs can be tightly spaced together in a narrow grid.

Controllers
The eco-CONTROL EC200 2.0 control system provides total control of preeflow volumetric valves during the dispensing process. It’s designed for either benchtop or rack-mounted location, dependent on the model.
Operating principle
The unit is operated via a bright, 7” touch screen, making it simple to use. External signals can be connected via I/O ports to a PLC for control in automated lines. Up to 100 dosing programs, with part management can be stored locally.
Error messages for filling level and motor current are also monitored (an RS232 interface is provided).
It is possible to control two eco-PEN precision volume dosing units (as a factory-fit option).
Features
- Quantity and start/stop program
- Set-volume readout in g or ml
- Dosing flow readout in ml/min and g/min
- Storage of up to 100 dosing programs with part management
- Set pressure and actual pressure readings in bar/psi
