Servo Pumps
High-efficiency servo-hydraulic systems for industrial applications.
Products and advanced control systems for energy efficiency and dynamic control
Servo pumps, or servo-hydraulic systems, are drive systems that combine a hydraulic pump with a brushless electric motor or servomotor and the related control electronics. This architecture enables extremely precise control of flow and pressure, high dynamics, reduced energy consumption and much lower noise levels than traditional hydraulic drives.
Fluid System is a technical partner of Bosch Rexroth, Baumüller and Atos, providing complete solutions, electro-hydraulic integration, selection support and after-sales assistance.
Servo pumps are now the reference technology for:
- injection presses and hydraulic presses
- high-dynamic machine tools
- industrial systems with variable, rapid duty cycles
- applications requiring energy saving and precision.
Servo-hydraulic technology: how it works
In a servo-hydraulic system, the hydraulic pump is no longer regulated hydraulically through compensators, but electrically, by modulating motor speed according to process demand.
This makes it possible to achieve:
• Energy generation only when required, with drastic reduction in consumption.
• Rapid start-up and braking to follow dynamic cycles.
• Pressure holding with almost zero absorption.
• Much lower noise levels than traditional systems.
• Longer service life of hydraulic components thanks to optimised transient management.
Types of Servo Pumps
Unlike conventional hydraulic pumps, servo pumps are not classified by pump operating principle, but by the architecture of the electro-hydraulic system.
Servo Pumps with Permanent Magnet Synchronous Motor (PMSM)
Ultra-high-efficiency systems with high dynamics and precise control even at low speeds. Ideal for machines with fast cycles, variable pressures and high-precision requirements.
Servo Pumps with Asynchronous Servomotor and Vector Control
Robust, versatile solutions particularly suited to industrial systems with continuous cycles and high power demand.
Integrated Servo Pumps (pump + motor + drive in one system)
Compact systems with integrated hardware, reduced wiring and simplified installation. Excellent for retrofit, compact machines and applications where space and installation speed are critical.
