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.
Features & Benefits
- Precise, process-stable dosing as small as 0.001ml (1μl)
- Accuracy of ±1%, >99% of the time
- Gentle product dosing process
- Linearly proportional control characteristics
- Wide control and application range
- Controlled reverse flow and clean product break
- Easy system integration
- Electronics packaging
- Biological chemistry
- Optics and photonics
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.
The unit is microprocessor-controlled. It is simple to operate, without submenu, 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.
The supply pressure (with pressure sensor kit) is monitored and can be displayed digitally in bar or psi.
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).

For applications where the material is supplied in syringe barrels, an optional cartridge adapter with an integrated ventilation system allows for direct dispensing from the syringe. With a 1/8 inch external thread, the adapter is ideally suited for the eco-PEN and eco-DUO series 300, 330 and 450. With the help of a reducer the adapter can also be used with the 600 and 700 series.
Made of black anodized aluminium and stainless steel, and FFKM sealing elements, the cartridge adapter is compatible with almost all materials. By means of a standardized Luer-lock connection (1), the material cartridge can be quickly attached to the adapter. The adapter itself can be turned by 360° without resistance until the final lock with the help of the hexagon screw (2), and thus allows the user a maximum degree of mobility and flexibility. With the aid of a small piece of hose (Øi 4mm) which is plugged onto the hose nipple (3) and by opening the bleed screw (4), the air can escape from the pump housing and any excess material can be quickly and cleanly disposed of together with the hose piece. In this way, air bubble-free dispensing can continue even after several cartridge changes.

See the preeflow eco-PEN as part of a real application in these dispensing and robotics Case Studies:
|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.
|Precision dispensing helps electrical manufacturer to reduce waste by improving quality and yield
By switching to an automated dispensing system, this electrical manufacturer reduced scrappage and therefore improved quality and yield of their product.
