Piston metering pump
0,12 - 1,48 ml/min | eco-PEN300
ViscoTec Pumpen- u. Dosiertechnik
makes possible many employments for the down to very viscous Dispensing range.
Preeflow® the eco PEN is rotary, absolutely pressure tight restrictor system a which self sealing, made of rotor and stator exists. Through to displace the medium in the stator the promotion is produced by the steered rotating motion of the rotor. Promoting without change of the medium is ensured. Since the promotion can take place also backwards, guaranteed preeflow® a clean, controlled material and/or medium outline without to after-drip.
All preeflow systems work according to the patented continuous piston principle.
