Preeflow®微量點膠機/分注器


The dosing technology of ViscoTec dispensers is based on the endless piston dosing principle. The special geometry allows for an endless, pulsation-free dosing flow with absolute volumetric control in either dot or bead applications.




High-precision Microdispensing Preeflow®微量點膠機/分注器
Preeflow High-precision Microdispensing

The brand preeflow stands for precise, purely volumetric dosing of liquids in small and smallest quantities. Based on more than 20 years of experience all around fluid dispensing “preeflow” was established in 2008 – and in addition also microdispensing in perfection. preeflow products are integrated in dispensing applications worldwide.

The unique quality – Made in Germany – turns them to essential components, for example in adhesive dispensing like 1-component or 2-component adhesives. If it comes to dispensers like the eco-PEN or eco-DUO, to control devices and evaluation units: preeflow products comply with our principle “small, precise, economical“.

1-component dispenser

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.

  • Valveless sealed technology without dripping
  • Dosing pressures of 16 to 20 bar are possible
  • Smaller needle and nozzle cross-sections
  • Pressure tank maybe dropped, depending on material
  • Smallest dosing quantity: 0.001ml
  • Dosing accuracy ± 1 %
  • Repeat accuracy > 99 %

eco-PEN300

Viscotec-preeflow-eco-PEN300

Smallest dosing quantity: 0.001 ml
Adjustable dosing flow: 0.12 – 1.48 ml/min
Weight: 380 g

The and innovative precision-volume-dispenser eco-PEN700 made by ViscoTec offers a wide range of applications for low to medium-viscosity dispensing.

Theory of function

preeflow eco-PEN 3D is a rotating and perfectly pressuretight 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.

eco-PEN330

Viscotec-preeflow-eco-PEN330

Smallest dosing quantity: 0.002 ml
Adjustable dosing flow: 0.2 – 3.3 ml/min
Weight: 410 g

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!

 

eco-PEN450

Viscotec-preeflow-eco-PEN450

Smallest dosing quantity: 0.004 ml
Adjustable dosing flow:  0.50 – 6.00 ml/min
Weight: 410 g

The eco-PEN450 precision-volume dosing unit made by ViscoTec covers many applications within the low to medium-viscosity dispensing range.

Theory of function

The preeflow eco-PEN450 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!

eco-PEN600

Viscotec-preeflow-eco-PEN600

Smallest dosing quantity: 0.015 ml
Adjustable dosing flow: 1.40 – 16.0 ml/min
Weight: 750 g

The eco-PEN600 precision-volume dosing unit made by ViscoTec covers many applications within the low to medium-viscosity dispensing range.
