Daikin to Launch Energy-Saving Hybrid Hydraulic Pump

Daikin Industries, Ltd. has developed a hybrid hydraulic pump called the "Super-Eco Rich" that can reduce power consumption by 95 percent. The Osaka-based company announced on August 24 that it will put this pump on the market in December 2005. Hydraulic pump systems are widely used for mechanical tools such as NC (numerically controlled) lathes and general industrial machinery, and the new system is expected to improve energy conservation capabilities to further promote energy savings at factories.

In the Super Eco-Rich system, the hydraulic pump stops operating when pressure is being maintained: it only operates when the pressure goes below a specified level. Consequently, the system can reduce power consumption to almost zero while pressure remains steady, a condition which accounts for 90 percent of overall operation time. The company estimates that the Super-Eco Rich system can help cut annual electricity bills for a variable piston pump-based system from 42,000 yen (about U.S.$372) to 2,000 yen (about U.S.$18).


This development can also reduce the amount of oil required, and thus downsize the oil tank by 70 percent and the overall unit by 60 percent. It can help reduce the size of machine tools as well as reduce waste oil.
