This efficiency is due to the optimised compression ratio, pump stage dimensions, and oil discharge path.
The pump is available with the Busch variable speed drive (VSD) Ecotorque, which enables the pumping speed to be adapted to the exact requirements of any process.
According to Busch, additional energy savings of up to 50% and a 20% increase in pumping speed can be achieved.
Additionally, the total number of spare parts has been reduced by 40%, making maintenance fast and efficient, with all service-related parts located on one side. Heat emissions have also been decreased through an improved cooling system that combines optimal pump operating temperature with compact construction.
The new vacuum pump is made for continuous operation in the rough vacuum range with vacuum levels down to 0.1 hPa (mbar). Field tests were successfully carried out to validate performance and reliability.
