Melt pump - BOOSTER-AT

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.

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.

Chemical pump hydraulically temperature controlled for a wide range of applications. This ranges from organic and inorganic chemicals to food oils, polymers and pharmaceutical products. A wide-ranging modular system provides optimum material combinations for corrosive or abrasive media.

Gear pumps with magnetic coupling The magnetic coupling is equal to contact-free drive and seal. Magnetic coupling pumps are used if critical media has to be transported. The seal ensures that the pumps work 100% securely and without leaking. The magnetic coupling is particularly ideal for hazardous substances that should not escape into the enviroment. The coupling is hermetically sealed and can be designed with different sensors for monitoring and in different variations and materials. A magnetic coupling is used in combination with a chemical pump by default.
