Gear pump for polymer processing PUMPS & TECHNOLOGY

The 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 Features BOOSTER classic Heat resistant carbon steel, e.g. 1.6582 (4340), stainless steel e.g. 1.4313 (E415) optional: coating Tool steel, nitrited steel, optional:...

Seals / Applications 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 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) with stuffing box The stuffing box can be used as an additional seal for the vis- coseal. The stuffing box is a simple (static)...
