Medium-viscosity - Import export

The CHEM gear pump series was developed especially for the requirements of the chemical industry. The series is used for pumping and transferring low to medium viscosity media. The CHEM series is extremely flexible in its design and areas of application. Technical details: — Suction pressures from vacuum up to 15 bar and suction pressures with magnetic coupling up to 25 bar — Delivery volume 1.28 cc/rev to 12,000 cc/rev — Temperatures up to 300 degrees — As special pumps for the chemical industry according to customer specifications — Viscosities up to 1.000.000 mPas

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.
