eco-PEN450 Precision Volumetric Micro Dispenser

PreeFlow eco-PEN450 Precision Dispenser

PreeFlow® eco-PEN450 volumetric micro dispensers are supplied with a drive and dispenser head consisting of a rotor & stator assembly, which have been purposely designed for easy maintenance.

The PreeFlow® eco-PEN450 works in a single axis with a self sealing rotor housed in a pressure-tight stator - this provides a simple, yet very effective positive displacement metering system.

The accurately controlled rotary motion of the rotor transfers the medium by proportional displacement in the stator.

The medium being dispensed is unaffected by this process, so shear sensitive material can be dispensed safely.

By simply switching to reverse-flow, PreeFlow® eco-PEN450 ensures a clean and controlled cut-off of material with....

NO DRIPS ..... NO STRINGING ..... NO MESS !!

 

Typical Applications for eco-PEN450

(1) Max. dosing pressure and self-sealing effect decreases as the viscosity reduces and gets higher as it increases. Please check with the manufacturer.

(2) Volumetric dosing tolerances based on one revolution of the dispenser rotor. Dependent on viscosity of dosing medium.
