A new vacuum system for conveying bulk solids
Among other products, this company will exhibit its new DZM series, a dry-running multi-claw vacuum pump system (photo), which is particularly suitable for the conveyance of bulk material. It is characterized by low-noise operation, as well as user-friendly plug-and-play installation. The DZM pumps achieve a pumping speed of up to 1,260 m³/h and can also be used as a central vacuum supply for handling tasks or extrusion processes. Since the claw-shaped rotors in the pump chamber, which rotate in opposite directions, neither touch each other nor the chamber wall, the vacuum pumps are very durable and reliable. The DZM models combine two to four DZM claw vacuum pumps in a compact housing, depending on the required delivery capacity. The pumps operate oil-free and air-cooled and also in harsh environments with little maintenance. One of the pumps, which can be combined for one DZM, operates in a speed-controlled manner, so that the generated vacuum can be adapted exactly to the requirements. This efficiency improvement reduces the necessary power and therefore the energy consumption and CO2 emissions. A final pressure of up to 140 mbar is achievable.
