Gear pump for extrusion

Gear pump for extrusion is mainly used in conjunction with extruders. Extrusion gear pumps provide consistent polymer flow, which results in more consistent product dimensions. It reduces the natural pulsation and irregular conveyance, particularly in single-screw extruders, added to which, the build up of pressure in the gear pump is more efficient in comparison to the extruder. Because of this, less energy or heat is transferred into the polymer and the product is conveyed in a gentler manner. The extruder is indispensable for the manufacture of precision films or micro granulate.

The robust construction and low wear materials make the extruder indispensable for extrusions. The versions are available for conveying plastic,rubber and fiber. The BATTE quick colour change version lends itself particularly to master batch applications with frequent changes of colour.

In order to prevent the pump's drive shaft from being driven/pushed out of the housing when there is a high pressure on the suction side (extruder conveying pressure), the drive shaft must be relieved. It protrudes from both sides of the housing and is sealed, so that atmospheric pressure predominates on both sides of the drive shaft. The shaft is thus relieved.

Gear pump for extrusion Applications:
Extrusion gear pumps are widely used in plastics, resins, rubber and chemical products extrusion. Such as: granulation, film, pipe, plate, sheet, synthetic fibers, fiber optics, medical plastic catheters and other industries.

Processable material covering almost the most polymeric materials, such as PE, PC, PP, PVC, HIPS, PS, PA, TPUR, fluoropolymers, polysulfones, polyesters, thermoplastic elastomer, rubber and adhesive fever.
