Ed Series Electro-Hydraulic Thrusters: The Intelligent Heart of Industrial Motion Control
The Ed series electro-hydraulic thruster is a compact, self-contained drive unit engineered to deliver precise, powerful, and reliable linear motion for a vast range of industrial applications. By seamlessly integrating a motor, centrifugal pump, and cylinder, it serves as the core actuator for:
- Industrial Brake Systems: Providing fail-safe release for block and disc brakes.
- Flow Control: Driving industrial valves and gates with precision.
- Mechanical Movement: Powering directional swings, rotations (up to 90°), and clamping devices.
Adhering to rigorous DIN 15430 and JB/T 10603-2006 standards, and built upon technology from the former German EMG company, every Ed thruster is a testament to quality and performance.
Advantages: Engineered for Your Demanding Applications
Why choose the Ed series for your next project? Because every feature is designed to solve a real-world industrial challenge.
1. Unmatched Reliability & Performance
- Robust Construction: The lightweight, fully sealed aluminum alloy shell (IP65 protection) ensures durability even in environments with high humidity or corrosive media.
- High-Endurance Motor: A non-oil-immersed motor with F-class insulation guarantees excellent heat resistance and a long operational lifespan, capable of up to 2000 cycles per hour (S3-60% duty cycle on standard models).
2. Precision Control Tailored to Your Needs
- Smooth, Shock-Free Operation: The hydraulic transmission ensures gentle actuation, reducing mechanical stress on your equipment.
- Customizable Speed: Enhance your control by adding ascent (H) and descent (S) delay valves, allowing you to fine-tune the operational speed to prevent load swing or system shock.
- Position Feedback: Integrate limit switches (E1, E2, EB) to send brake open/closed status signals back to your PLC, enabling smarter, automated control.
3. Versatility Across a Comprehensive Range
- Wide Performance Spectrum: Our range covers everything from the compact Ed 23/5 (220N thrust, 50mm stroke) to the powerhouse Ed 630/12 (6300N thrust, 120mm stroke), ensuring a perfect match for any load.
- Flexible Installation: Thrusters can be installed vertically or horizontally. The mounting base on models Ed 50 through Ed 301 can be rotated 90°, offering unparalleled installation flexibility.
4. Built for Extreme Environments
- Wide Temperature Range: Standard units operate flawlessly from -20°C to +50°C. For colder climates, an optional heater (R) can be integrated.
- Anti-Corrosion Options: Specialized anti-corrosion treatments are available for marine or chemically aggressive environments.
Working Principle: The Power of Controlled Hydraulic Force
The Ed thruster’s operation is elegantly simple and inherently fail-safe.
- Activation: When power is on, the internal motor drives a centrifugal impeller.
- Pressure Build-Up: The impeller generates hydraulic pressure, forcing oil to act upon a piston.
- Linear Motion: The piston and its attached push rod rise smoothly, compressing the brake’s main spring and releasing the brake.
- Fail-Safe Deactivation: Upon power loss, hydraulic pressure dissipates instantly. The brake’s spring force pushes the piston back, ensuring the brake engages immediately and safely holds the load.

Customization & Accessories: Build Your Perfect Thruster
Enhance the functionality of your Ed thruster with a range of bolt-on accessories.
| Code | Accessory | Function |
|---|---|---|
| H / S | Delay Valves | Adjusts ascent (H) or descent (S) time for soft actuation. |
| E1 / E2 | Limit Switches | Provides mechanical position feedback (e.g., brake released/closed). |
| EB | Inductive Switch | Offers contactless position sensing for high-frequency applications. |
| R | Heater | Ensures reliable operation in ambient temperatures below -20°C. |
| C / M / D | Internal Springs | Adds brake spring force (C), reset force (M), or buffering (D). |
Example: An Ed 121/6-S-E2 is a thruster with 1250N thrust, 60mm stroke, equipped with a descent delay valve and a “brake closed” limit switch.
Installation & Usage Best Practices
- Mounting: Ensure the piston rod is aligned with the load to avoid radial forces, which can impact performance and lifespan.
- Environment: For highly corrosive or dusty areas, please specify the need for special seals or anti-corrosion treatment when ordering.
- Electrical: Confirm your supply voltage and frequency. All units are tested before shipment to meet your specified electrical requirements.
