Vacuum degassing during the extrusion process by means of liquid-ring vacuum pumps is a cost-effective and reliable solution for removing gases and impurities from the plastic melt.
The compact series of LRM liquid-ring pumps has a capacity from 28 to 515 m3/h and, thanks to various optional components, such as a separator, heat exchanger, control valves, can be perfectly adapted to the technical features of the extruder.
Due to the robust and reliable design of liquid ring pumps, they are insensitive to condensate, impurities and high temperatures during the pumping process. Thus, the ZME pumps of the LRM series have an undeniable advantage over dry types of vacuum pumps in plastic processing.
