Pneumatic pumps for the extrusion of high density products
PUMPS FOR EXTRUSION
Differently from the normal pumps, the extrusion pumps allow the pumping of very viscous materials, which are not able to flow directly to the aspiration mouth of traditional pumps.
Usually extrusion pumps are assembled on pneumatic rams which allow to suck the product directly from the drum and to replace it rapidly.
A follower plate at the base of the pump compresses the material, avoiding the phenomenon of cavitation, assuring a constant flow and protecting the product from contaminations (air, dust, moisture).
