About preeflow® eco-PEN Precision Volumetric Dosing Pump, for Highly Accurate Repeatable Dispensing

The preeflow eco-PEN is a precision volumetric, positive displacement, dosing/dispensing system that gives you accuracy and repeatability by means of a rotor which turns inside a stator. The preeflow eco-PEN uses a progressive cavity pump principle which doses and dispenses a wide range of material viscosities with no stress to the material, and absolute control.

   

preeflow eco-PENs can be integrated into any of our robotic dispensing systems. The preeflow eco-PEN delivers optimum results when used with Preci-Tips Precision Dispensing Tips.

Features & Benefits

  • Precise, process-stable dispensing as small as 0.001ml (1μl)

    preeflow eco-PEN suck back
    Demonstration of controled suck-back
  • Highly repeatable and consistent dispensing, with an accuracy of ±1%, >99% of the time
  • Gentle product dosing process using positive displacement
  • Linearly proportional control characteristics
  • Wide control and application range
  • Controlled reverse flow and clean product break
  • Easy system integration, including as part of our archytas series of robot integrations

Applications

The preeflow eco-PEN is designed for dot-dispensing, bead application with dispensing rate adjustable to the run speed, and encapsulation applications for:

  • Electronics packaging
  • SMD/SMT
  • Semiconductor
  • LCD/LED
  • Medical device assembly
  • Biological chemistry
  • Laboratory
  • Photovoltaic
  • Optics and photonics

 

Controllers

preeflow dispensing system preeflow EC200-B control unit

The eco-CONTROL EC200 control system provides total control of the dispensing process. It is designed for either benchtop or rack-mounted location, dependent on the model.

Operating principle
The unit is microprocessor-controlled. It is simple to operate, without sub-menus, and has graphic support. External signals can be connected via I/O ports to a PLC for control in automated lines. A wide variety of dosing programs with part management can be stored.

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 program
  • Start/stop program
  • Time program
  • Set-volume readout in g or ml
  • Dosing flow readout in ml/min and g/min
  • Storage of dosing programs with part management
  • Set pressure / actual pressure reading in bar/psi

Other Information

Syringe adapter with integrated bleed valve

For use in applications where the chosen material is supplied in syringe barrels, an optional adapter with an integrated bleed valve allows for direct dispensing without the risk of air bubble formation.

Cartridge adapter for preeflow eco-PENs

Made of black anodized aluminium and stainless steel, and FFKM sealing elements, the syringe adapter is compatible with almost all materials and allows for air bubble-free dispensing, even after several syringe barrel changes.

With a 1/8-inch external thread, the adapter is well suited for the eco-PEN, eco-DUO series 300, 330 and 450 and eco-DUOMIX450.

Set-up and maintenance

Setting up your eco-PEN is fast and straightforward. preeflow have put together an easy to follow video which will guide you during your first set up.

For information on how to maintain and clean your eco-PEN watch preeflows video tutorial.

Case studies

See the preeflow eco-PEN as part of a real application in these dispensing and robotics Case Studies:

Case Study F4300N.1 preeflow eco-PEN GJD Manufacturing Automated dispensing helps security manufacturer increase throughput and quality

GJD Manufacturing switched to an automated method of dispensing silicone for sealing a plastic lens to aluminium housing. By doing this, they improved the throughput and quality of their white-light and infra-red LED illuminators for the security industry.
