BOOSTER - Gear Pump For Polymer Processing Brochure

CHEMEXTRUPOLYBOOSTERPUROBOOSTER Gear pump for polymer processingBOOSTERThe reliable transfer and booster gear pump for polymer processing Gear pumps are used in the polymerization process, to boost the pressure of medium to high viscosity media. They transport pre-po-lymers and polymers, e.g. PET, PBT, PS, ABS and many more, very gently Heating is either by way of heat transfer oil or steam. The core components like shafts and friction bearings originate from the WITTE building block system.Technical FeaturesHousing: Heat resistant carbon steel, e.g. 1.6582 (4340), stainless steel e.g. 1.4313 (E415) optional: coatingGears: Tool steel, nitrited steel, optional: special steel, surface coating, helical gearing herringbone gearing (for extremely low-pulsation conveyance)Friction Bearings: Tool steel, Al-bronze, NiAg (nickel-silver), special materials optional: surface coatingShaft Seal: Viscoseal, vacuum viscoseal, stuffing boxHeating Systems: Heat transfer oil, steam The values listed are maximum values and must not coincide under certain circumstances.Operating ParametersViscosity: Up to max. 40.000 Pas Temperature: Up to max. 350 °C (662 °F)Suction Pressure: Vacuum up to max. 120 bar (1.740 psig)Differential Pressure: Up to max. 250 bar (3.626 psig)Application ExamplesPolymers: PET, PBT, PA, PC, PS, SAN, ABS, HIPS, PP, PE, POM, BiopolymersPump SizesFrom 22/22 (4,7 cm3/rev) up to 280/280 (12.000 cm3/rev).ill.

This is a dynamic seal for high viscosities and suction pressures. It can be provided with heating or cooling. The dynamic seal is suitable for high pressures and temperatures. Its range of use is limited by the suction pressure and the viscosity of the medium being conveyed (at least 50 Pas). The viscosity can be increased by an additional cooling system if necessary.Viscoseal (VS)The stuffing box can be used as an additional seal for the vis-coseal. The stuffing box is a simple (static) seal for WITTE gear pumps. It can be provided with buffering if so desired. The range of application is similar to that of the viscoseal. The standard material used for the packing is made of expanded pure graphite with structural textile fibers. But it goes without saying, that other materials are also available.Viscosity (stuffing box): max. 10.000 Pas Temperature: max. 350 °C (662 °F)Viscoseal (VS) with stuffing boxill.
