For dosing 1-component fluids

preeflow® eco-PEN

A volumetric dosing system for precise dispensing that is able to apply minimum quantities of one-component fluids. Due to the ViscoTec endless piston principle watery up to pasty fluids can be feeded perfectly.

Independent from viscosity fluctuations a clean and process reliable dosing can be realized. The controlled cutoff thanks to the suck-back effect marks the preeflow devices of the eco-PEN series next to many other features.

Description

The innovative precision volume dosimeter eco-PEN 300 made by ViscoTec offers a wide range of applications for low to high-viscosity dispensing.

Theory of function

preeflow eco-PEN300 is a rotating and perfectly pressure-tight displacement system. Self-sealing rotor/stator design. Conveyance action by medium displacement in the stator through controlled rotor rotation. Safe conveyance without any modification of the medium. With its suck back option, preeflow ensures clean and controlled material or medium cut-off while preventing post-dripping effects.

Description

The micro dispenser eco-PEN330 is the missing link in micro dispensing!

Theory of function

Like all products in the eco-PEN series also the preeflow eco-PEN330 is a rotating, absolutely pressure-tight, positive displacement system with self-sealing rotor-stator arrangement. The controlled rotary motion of the rotor transfers the medium by displacement in the stator. The medium is unchanged by this process. And simply by switching to reverse-flow, preeflow ensures a clean and controlled stop of material or medium. No drips, no mess!

Control units

Description

The control unit, eco-CONTROL EC200-K, made by ViscoTec, offers the precision-volume dosing unit of the eco-PEN series many application possibilities.

Theory of function

The unit is microprocessor-controlled. It is simple to operate, without submenu, and has graphic support. The set supply pressure is monitored and digitally displayed in bar or Psi. Error messages for filling level and motor current are also monitored. 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 are storable.

Theory of function

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 are storable. The supply pressure (only 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).

Description

The preeflow Speed Control ‘plug’n’dose’ TP control unit allows you to control the eco-PEN using a simple time/pressure control unit.

Theory of function

Microprocessor-controlled. The supplied pressure adapter is connected to a conventional time/pressure control unit. The flow rate and flow speed of the eco-PEN are controlled using the specified pressure and a time mode.
