The disc-impeller is eccentrically pivoted on the pump and is driven by the diaphragm that separates the inlet from the outlet. During the rotation of the disk is kept close to the body by the pressure of the spring elastic device.
Front view of one of the operating balance of the disc, autoadattanti, volumetric, M pompe
Operating example, oscillating hollow disk remains close to the body
Operational diagram 3 pump-priming reversible. Elasticity of the impeller allows adaptation to all viscosity
Operational diagram 4 self-priming pump, it automatically also luring a unleveled condition
In each position the disc is radially and axially balanced:
The arcs AB and AC have equal internal and external pressure. There are parts that tend to remove the disc from the body. The resulting pressure was constant and tangent to the circle described from the center of the disc.
The high degree of in-take vacuum (500 -600 mm. Hg) allows the pumps to prime automatically without having to be filled in advance and with no need of foot valve.
The running direction can be reversed to invert the flow of fluid without altering the technical characteristics of the pump.
Low Running Speed
Permette l’adattamento a tutte le viscosità, il passaggio di particelle solide ed il recupero dei giochi dovuti ad usura o dilatazioni termiche.
A special mechanical spring device allows the impeller to be always pressed towards the external wall of the chamber, thus enabling its adaptation to all viscosities, the recovery of any slack, the elimination of thermal expansions and passage of small foreign bodies.
Graphic disc rotation, displacement pump, low impeller speed is suitable for viscous liquids.
