DFEn 5000 System


The Sytronix DFEn 5000 is suitable for use in open hydraulic systems for pressure and flow control. It covers a performance range up to max. 630kW and is used preferably in presses, plastics machines, and also in the wood and metal industry.

Your Benefits

  • High energy savings, reduced operational costs

    Depending on the cycle characteristics of the application, Rexroth's Sytronix DFEn Variable Speed Pump Drives produce energy savings up to 45% compared to variable pumps with constant speed. Lower power consumption leads to lower energy costs and CO2 emissions, and allows companies to reduce their "carbon footprints".

Reduced noise level, less effort for secondary measures

  • There will be less noise with partial-load operation, thanks to needs-based reduction of the pump speed. The result: noise level reduction by 20 dB(A), which reduces the necessity for secondary measures for sound insulation.

Reduced cooling costs, short amortization period

  • In many cases, no further actions will be necessary to cool the hydraulic power unit because the energy influx into the hydraulic fluid is greatly reduced due to the lower speed.

Compact designed space

  • Lower cooling costs allow for a more compact design, which also reduces the system's complexity and acquisition costs.

Increased machine performance, downsizing

  • A temporary increase of the speed, e.g. to 1800 rpm, boosts the delivery volume and thus the peak performance. Under certain circumstances, the engineer might be able to cope with smaller design sizes.

Less installation and start-up expenditures

  • Several pump circles on an engine shaft, internal oil controls supplies, pre-configured engine pump units, component parameters that are coordinated with each other, and easy-to-use project software allow for a clear system overview with relatively short installation and start-up times.

High machine availability

  • Sytronix DFEn Variable Speed Pump Drives are based on optimally coordinated and proven parts of high availability.

Future-proof technology

  • Rexroth's Sytronix DFEn Variable Speed Pump Drives comply with EC Directive No. 640/2009.

Easy integration of flexible control functions

  • Costly machine breakdowns can be avoided through advanced diagnostics and condition monitoring options.

Simple retrofitting, design adjustments

  • Identical interfaces to SY(H)DFE optionally offer the possibilities of simple retrofitting for the machine operator or by the engine manufacturer.
