Melt pump for the production of medical flow. Melt pumps of this type are used, among other things, in the production of medical fluids, such as those used in respiratory masks. The melt-blown fluid can be used in many different ways in protective masks or filters. The EXTRU series is exkat adapted to the requirements of the melt-blow process and thus works with highest precision.

Melt pump for building up pressure in the polymer process. The series is the result of a complete revision of the core components used. The BOOSTER-AT is available with flange connections according to EN1092-1 and ANSI B16.5. Thanks to the new gear wheel geometries, differential pressures of up to 320 bar are possible with selected pump sizes. The new design is rounded off by the usual variety of different material combinations. Advantages: Higher efficiency, therefore Less temperature input into the polymer Wider viscosity range possible Larger volume flow range possible Increased safety against shaft breakage in case of overload due to new design

EXTRU - Melt pump for extrusion and pressure increase of medium to high viscosity media. The extrusion gear pump is mainly used in combination with extruders or kneaders. It reduces the natural pulsation of the extruder and compensates for fluctuations in delivery, especially in single screw extruders. The extrusion pump is used as a melt pump. It builds up the required feed pressure, which is needed for the downstream die. The pressure build-up in the gear pump can be much more efficient than in the extruder itself. The extruder is relieved by using an extrusion pump. Furthermore, considerably less energy or heat is introduced into the polymer. The melt pump thus contributes to conveying the product as gently as possible. The EXTRU is indispensable for the production of precise films or micro pellets.

The reliable booster pump for the polymer process. BOOSTER gear pumps from WITTE are used in the polymerisation process to increase the pressure of medium to high viscosity media. The hydraulically heated booster pump conveys very gently prepolymers and polymers, such as PET, PBT, PS, ABS and many others. Heating is by means of heat transfer oil or steam. The core components such as shafts and slide bearings come from the WITTE modular system. The booster pumps of the BOOSTER series are used wherever particularly high pressure is required for the process. High pressures are required for pelletising, fibre production or for spinning pumps, among others. The design of the BOOSTER booster pumps can be adapted to the needs of the plant and the customer's requirements.

Melt pump for the production of HDPE / LDPE / LLDPE. Melt pumps of this type are used in the production and processing of HDPE / LDPE / LLDPE. The EXTRU series is exkat adapted to the requirements in these processes and thus works with highest precision. Special serrations allow an almost pulsation-free conveyance of the melt, which guarantees a constantly high product quality.

The POLY-AT design offers exceptional flexibility when it comes to installations beneath the polymer melting reactor. Customers can choose from three different flange geometries to ensure they are always benefiting from the best combination of reactors and pump flanges from both a technical and economical perspective. The new gear geometries facilitate differential pressures of up to 320 bar for selected pump sizes. What’s more, the new design is rounded out with the usual variety of different material combinations. The most common of these combinations has to be a stainless-steel or carbon-steel housing with tool steel or aluminium-bronze friction bearings.
