Hydraulic Power Unit offers quiet operation.
Press Release Summary:
September 23, 2004 - Hydraulic Power Unit features U-shaped tank containing motor-pump group that mounts on anti-vibration pads to insulate source of noise. All components are accessible and allow further modules such as accumulator stations or IH20 control blocks to be mounted. Suction and return lines, installed wide apart, ensure separation of air in oil. Stainless steel version allows use of any media. Fixed-displacement pump minimizes power losses in circulation mode at almost zero pressure.

Bosch Rexroth Introduces Energy-Efficient, Whisper-Quiet Hydraulic Power Units
Press release date: September 20, 2004
With energy savings of up to 80% and a noise reduction by up to 15 dBa Rexroth sets new benchmarks with regard to energy-saving and low-noise hydraulic power units in machine tools.
The new power unit has been redesigned to achieve ultra low noise and drastically reduced energy consumption. A U-shaped tank with the motor-pump group mounts on anti-vibration pads to effectively insulate the source of noise. All components are easily accessible and allow further modules such as accumulator stations or IH20 control blocks to be easily mounted. The suction and return lines are installed wide apart, thus guaranteeing a good separation of air in the oil. The stainless steel version allows the use of any media.
The fixed-displacement pump always operates with high efficiency and reduces power losses in the circulation mode at almost zero pressure. Energy savings of up to 80% can be realized. Depending on the application, the accumulator charging circuit even makes a cooler superfluous.
Rexroth offers the combination of whispering power unit and accumulator charging circuit as an assembly that is ready for installation and thus presents a practical alternative for complying with legal provisions of noise control and reducing commissioning costs.
Bosch Rexroth Corporation, a merger of Bosch Automation Technology and Rexroth, is a wholly owned subsidiary of Robert Bosch GmbH. In the year 2003, Bosch Rexroth AG achieved sales of $4.4 billion (3.7 billion Euros) with 25,700 employees.
Under the brand name of Rexroth, the company offers all relevant drive, control and motion technologies: from mechanics, hydraulics and pneumatics to electronics and associated services. Rexroth has 500,000 customers in over 80 countries and is an extensive supplier of components and systems for industrial and factory automation and mobile applications.
