    Advertising

    The new rotary vane vacuum pump R5 RA 0520 A from Busch increases energy savings by up to 25%. It features a compact and hygienic design, reduced heat emissions, and enables faster and easier maintenance. The optional ECOTORQUE variable speed drive provides up to 50% additional energy savings and a 20% increase in pumping speed.

    The proven R5 RA from Busch now comes in an improved version with a completely redesigned interior. The new vacuum pump is 25% more energy efficient than its predecessor, thanks to the optimized compression ratio, pump stage dimensions, and oil discharge path.

    It is also available with ECOTORQUE, the Busch variable speed drive (VSD), that enables the pumping speed to be adapted to the exact requirements of any process. As a result, additional energy savings of up to 50% and a 20% increase in pumping speed can be achieved. The accessory extends the supply voltage range supported by the vacuum pump, making it suitable for use in almost all countries around the world. This compact and cost-effective solution is also available as a retrofit.

    Compared to the previous generation, the R5 RA 0520 A has a 20% smaller footprint, is 25% lower in height, and the absence of external piping improves leak tightness. The compact and hygienic design features surfaces that repel water and dirt. 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.

    The R5 RA 0520 A and the R5 RA 0520 A ECOTORQUE set a new standard in vacuum technology. The pumps are suitable for various applications in vacuum packaging, food and plastics processing, and many other industries. They are an excellent choice for companies looking to improve their processes while minimizing energy costs and reducing their environmental impact.
