Servo pumps
Intelligent use of hydraulic oil
Baumüller has launched a new servo pump version on the market. The hydraulic pump is attached directly to the engine with gearing. This eliminates the need for a clutch and bellhousing as with classic servo pump versions.
This results in a shorter installation length and consequently a smaller machine footprint. The direct attachment also eliminates the need for mechanical parts. In addition, connections have been added to both the motor and the fixed displacement pump so that the leakage flow from the pump can be used to permanently lubricate the gearing. This eliminates the need for grease lubrication of the internal gearing, which is due on average every 3000 operating hours. The machine can produce without interruption. As the connection holes are available on both sides, the motor can be installed vertically or horizontally depending on the application. The motor position can therefore be freely selected and adapted to the respective machine design. The new features are available for the three-phase synchronous motor series DSD2 in sizes 71 and 100; size 132 will follow shortly.
