Electro-hydraulic pumps combine electric and hydraulic technologies to create a compact, energy-efficient system that generates hydraulic pressure through an electrically driven pump unit. They are used in applications where flexible, precise, and quiet operation is essential – such as in mobile machinery, industrial systems, and electrified vehicle platforms.

An electro-hydraulic pump consists of an electric motor driving a hydraulic pump, often integrated into a single unit together with control electronics and system monitoring. The motor can be brushless (BLDC) or asynchronous and is electronically controlled to adapt flow and pressure based on real-time system demands. When the electric motor is activated, it generates motion that powers the hydraulic pump, which in turn delivers pressurized oil to operate cylinders, motors, or other hydraulic functions.
Electro-hydraulic pumps are available with both fixed and variable displacement. A fixed-speed pump provides a constant flow whenever it is running, making it a simple and robust option for systems with steady load requirements. With variable displacement, the motor speed is dynamically adjusted, allowing for precise regulation of pressure and flow. This improves energy efficiency and responsiveness, especially in systems with fluctuating loads or where fast movements are required.
Electro-hydraulic pumps offer significant advantages in terms of energy efficiency, as the motor only operates when pressure is needed. This reduces overall energy consumption compared to traditional hydraulic systems running continuously. These units also operate quietly and require minimal maintenance thanks to fewer mechanical components. Their compact design makes them easy to integrate into mobile machinery or installations with limited space – without compromising on performance.
Electro-hydraulic pumps are increasingly used in electrified vehicles and machinery, such as construction and agricultural equipment, where there’s a need to replace combustion engines or reduce energy consumption. They are also common in stationary industrial systems like robotic cells, lifting equipment, test benches, and specialized machinery requiring precise motion control. Thanks to their flexibility and efficiency, they are also an excellent choice for applications in renewable energy, logistics, and industrial automation.
