WITTE PUMPS & TECHNOLOGY GMBH

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.

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.

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.

Melt pump specially designed for use in the production of medical tubing made of TPE, PE or PA. The melt pump is installed downstream of the extruder in the extrusion process for pressure build-up and constant delivery of the melt to the die. It is particularly important for medical tubing that the wall thickness and quality is absolutely constant and uniform.

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.

We bring our success, our wealth of experience and our know-how to the chemical industry. The requirement to pump viscous and sticky substances out of a vacuum is no easy task. However, our CHEM design easily meets this requirement. The requirements for dosing and transfer pumps as well as for distillate pumps in the CBD segment, for example, also match our CHEM design so that you get a pump solution for your entire distillation process with just one pump. More than 600 pumps of this design are running reliably in a wide range of cannabis applications at a number of our US customers. This robust and reliable pump series is used worldwide in demanding processes in the chemical and pharmaceutical industries.

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.
