The preeflow® eco-PEN700 is a rotating, pressure-sealed displacement system. It consists of a stainless steel rotor and an elastomer stator that together form a closed system. With this arrangement a closed "single volume" chambers are created. Through the rotation of the stator, the volume chambers are pushed further and through it, controlled dispensing of the material is generated. The system is self-priming with low viscosity products. EC200-K is required for activation. Volume flow 5,3 to 60,0 ml/min.
