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.
These pumps achieve the best efficiency through optimized shaft and bearing geometry. The need for energy is kept low allowing the operating costs to be optimized. The POLY is offered in different variations. Versions with classic or shortened inlet geometries are just as possible as versions in the LowNPSH Design.
Pumps with shortened inlets guarantee the quick feed of melt to the gear pumps. All POLY discharge pumps have the largest possible inlet openings with optimized flow geometry to avoid increased friction, decelerated inlet of the medium into the pumps as well as to reduce additional heat input. Different material combinations make these pumps reliable partners in the polymer industry, which can also be operated reliably under the most extreme of conditions.
