Extrusion gear pump PUMPS & TECHNOLOGY

The EXTRU is mainly used in conjunction with extruders or kneaders. The EXTRU is essential for precision films extrusion or micro granulate conveyed in a more gentle manner. particularly in single-screw extruders. The pressure build up 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 It reduces the natural pulsation and irregular conveyance, pelletizing. The EXTRU is an essential component of modern extrusion lines, its robust design minimizes down times of production lines. The WITTE -...

Pump Sizes From 22/13 (2,78 cm3/rev) up to 280/280 (12.000 cm3/rev). Intermediate sizes, with narrower gearwheels for higher differential pressure, are possible, e.g. 140/90 (690 cm3/rev) Operating Parameters Suction Pressure: Differential Pressure: Up to 250 bar (3.626 psig), special models also available for higher differential pressures The values listed are maximum values and must not coincide under certain circumstances. The viscoseal is the standard seal for WITTE EXTRU- and BOOSTER- pumps. This is a dynamic seal for high viscosities and suction pressures. It can be provided with...
