How To Repair A Magg Ex Pump
Pump Technology Melt Pump Technology for Production of Bioplastic PLA
The Maag Group has supplied its latest state of the fine art x6 form melt pump technology for the first fully integrated saccharide-to-PLA (polylactic acid) plant in Red china. The found is based on a Sulzer technology and key equipment for converting lactide into PLA.

The lactic acrid and lactide production is made from sugars (in this case won out of locally grown corn). Not only is the plant reducing the carbon footprint because of using plant-based resources instead of hydrocarbons simply past using the company's pump engineering, the specific free energy requirement is further optimized.
The firm's pumps are used in the polymerization reaction stage, making sure that the efficient Sulzer SMRTM reactors are working smoothly in all operating weather. But they are besides used in the devolatilization stage, where, a minimum level is required when unreacted lactide is removed from the PLA melt to achieve a good product quality. In the last stage, the company's melt pumps are used to build up the necessary pressure to process the melt through the downstream equipment, up to the underwater pelletizer.
The cook pump technology's key feature is the reduced dorsum-flow to lower the energy consumption. The cook pump helps to salvage up to 50 % energy and reduces material recirculation in the pump of about fifty %, states the company.
While the reduction of 50 % of energy is possible in exceptional cases and in extreme operating conditions only, the trend is truthful for all the applications when the business firm'due south technology is used. With the free energy saving, as well the CO2 footprint is reduced, adds the company. But the pumps offer far more than that. The high efficiency of the pumps is offering a wider operating range as compared to other state of the art technologies. It allows for example that depression sticky pre-polymer can safely be processed through the Sulzer plug flow reactor when the polymer conversion is progressing and the viscosity is continuously increasing in the same, opines the firm.
The high efficiency of the technology keeps the bearing temperatures lower than in quondam pump technologies, assuasive always a stable picture of polymer, lubricating the turning shaft. The favorable shaft geometry, where the length over center altitude ratio has increased, allows the operation of extraction pumps at a lower fill level than it was ever possible before at a given connection size to the vessel, mentions the company.
Just like this the PLA can fully be full-bodied. Simply also, the reliability has increased. Not merely are the bearing surfaces almost 30 % bigger, providing a better cushioning, but the pump is also working with bigger gaps, allowing potentially small foreign particles inbound the system to pass the pump easier without damaging it, concludes the company.
