The demands on plants, processes and equipment are constantly increasing. So to live up to the demand for greater efficiency, higher throughput and lower reject rates, Witte Pumps & Technology GmbH has completely overhauled its entire range of polymer pumps. In a bid to achieve more through put, gentler handling and greater energy efficiency, the pumps in both the BOOSTER and POLY ranges have been entirely reworked.
The result is a redesign that impacts on all core components: friction bearings, housings and gear shafts have all been modified. From a technical perspective, this has meant real advantages in terms of conveying properties and product qualities thanks to the reduced heat input, lower shear and shorter dwell times of the polymer in the smelting reactor. What’s more, the optimised gear shafts and modified housing geometry facilitate significantly higher throughputs than with pumps of the same footprint in the previous design. This in turn allows for increases of up to 40% without changing the installation size.
POLY-AT an BOOSTER-AT pumps offer customers multiple advantages over conventional pumps. For example, AT pumps achieve significantly higher throughput than pumps in classic design with the same footprint. The 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.
