A dosing pump with more features, better performance

| By Mary Page Bailey and Gerald Ondrey

With the vipro-PUMP series (photo), this company is launching a totally new generation of dispensers. A new design, optimized dosing components and modular construction provide numerous opportunities for adapting the dosing equipment even more effectively to the relevant application. The core of the new generation is the modular design of the dispenser. On the one hand, the separable rotor assembly allows fast installation and removal of its components. On the other hand, variable rotor and stator materials ensure optimum dispenser performance — for example, a ceramic rotor with matching stator is ideally suited for abrasive media, while an HVC rotor is used for standard applications (for example, adhesives). An enlarged pump inlet minimizes pressure loss, improves the material flow and allows easy attachment and detachment of the hose supply. Two larger modular-bleed openings ensure a user-friendly and clean bleeding process and ultimately help to guarantee dosing with no air bubbles. The new stator design has an anti-rotation device and a defined non-positive connection to allow easy and intuitive assembly. Various drives can be attached to the dispenser using a locking ring and the newly designed coupling. The flowplus-SPT M6 measures pressures up to 40 bars and temperatures up to 50°C. — ViscoTec Pumpen- u. Dosiertechnik GmbH, Töging am Inn, Germany
