Hydraulic Pump Systems

Electro-hydraulic control systems

The Rexroth-SYDFE Electro-hydraulic control systems are energy efficient, robust & highly efficient, ensuring accurate regulation of pressure, flow & power. 

With a design based on an axial piston variable displacement pump, these systems control pressure, flow & power without throttling losses in the energy line.

Variable speed pump drives – Sytronix

Our portfolio of variable speed pump drives connect standard components from hydraulic and electric systems to form customised, intelligent & cost-efficient systems.

Our range includes Sytronix & electro-hydraulic control systems, delivering dynamic and high-precision control. These are designed to ensure less current, less noise and lower operating costs.

The range also includes pressure control systems, including the

• EcP (a good option for small to mid-sized machines, designed to meet strict noise limits while ensuring smooth operation) & DRn (a powerful, dynamic and cost-effective solution for larger drives from 4 kW & up, using a frequency converter to manage the operating speed).
• p/Q control systems, consisting of a synchronous servo motor with permanent magnet & an easy-to-operate frequency converter. Thanks to the use of internal gear pumps, these are particularly quiet.

Secondary controls

Our secondary-controlled drives combine high dynamics with control accuracy and energy recovery, for a reliable and high-performance solution. 

These secondary controls offer exceptional precision and easy operation, a high degree of reliability and availability and highly dynamic speed and torque. They’re flexible and require minimal installation space.

Secondary-controlled drives from Bosch Rexroth are ideal for use in a wide range of applications, including machine construction, marine & offshore, test benches, as well as material handling and transport. 

Solutions in this range include:

• A4SO-DS3 secondary control with axial piston units
• A4VSG-DS3 secondary control with axial piston units
• MLC-SEK digital controller assembly for the secondary control of axial piston units
