Polymer discharge pumps

Reliable and robust pumps are needed to empty reactors and containers particularly during the polymerization process. The pumps transport the melt throughout the process. The highly viscous material must be transported from a reactor under vacuum. Discharge pumps from the POLY series from WITTE are specifically created for this task. The customer can choose between a standard design or an individual design according to their requirements.

Operating parameters

Viscosity
Up to 40.000.000 mPas
Temperature
Up to 450°C
Suction pressure
Vacuum up to max. 40 bar
Transport pressure /differential pressure
Up to 320 bar (4642 psig). The values listed are standard values and must not coincide under certain circumstances. Others values are available upon requests.
Pump sizes
From 4.7-22-22 (4.7 ccm/rev – 10 kg/h) to 25,000-360-360 (25,000 ccm/rev – 52,000 kg/h). Sizes with wider gear pumps for lower differential pressures are available by default, for example, 3,170-152-254 (3,170 ccm/rev).
