Fisnar PosiPump™ I-Series Progressive cavity valve
The PosiPump™ I-Series Progressive cavity valve offers true volumetric dispensing allowing the user to achieve exceptional levels of repeatability.
The proven endless piston design principle ensures a constant volume is always dispensed, regardless of any changes in fluid viscosity, thixotropy or fluid inlet pressure. Bi-rotational control ensures a drip free dispense cycle thanks to an infinitely adjustable suck-back feature.
Dispense volume as small as 0.008ml
Constant volumetric & pressure-stable dispense system
Dispense volume is not affected by changes in fluid viscosity or feed pressure
FKM or FFKM Stator Material
Long service life
Compatible with industry standard mixing nozzles
No dripping/drooling after dispense cycle
Suitable for both low & high viscosity fluids
Pressurisation of fluid feed system is not necessary for self-levelling low viscosity fluids
Prevents damage to fillers in filled fluid materials
High level of process control
