Batte
extrusion pump is mainly used in conjunction with extrusion pumpders or kneaders. It reduces the natural pulsation and irregular conveyance, particularly in single-screw extrusion pumpders, added to which, the build up of pressure in the gear pump is more efficient in comparison to the extrusion pumpder. Because of this, less energy or heat is transferred into the polymer and the product is conveyed in a gentler manner.
