Compact Explosion-Proof Hydraulic Station - ATEX Certified Explosion-Proof Hydraulic Power Unit
Specialized in manufacturing small explosion-proof hydraulic stations. Certified by ATEX/IECEx for explosion-proof purposes. Designed specifically for automation equipment in explosive environments such as those in the oil, chemical, and mining industries, these units offer safe, compact, and efficient hydraulic power. Customization is supported, and a one-stop solution is provided.
Our small explosion-proof hydraulic station (also known as an explosion-proof hydraulic power unit) is an integrated hydraulic power source specifically designed for hazardous environments where there is potential for explosive gases, vapors, or dust. It integrates explosion-proof motors, hydraulic pumps, oil tanks, control valve groups, and safety protection devices into a compact framework, aiming to provide absolutely safe, stable, and efficient power output for various hydraulic-driven automated equipment. Whether it is used to drive fixtures, lifting platforms, valve actuators, or testing equipment, it is a key foundational component for ensuring safe production and automation upgrades in industries such as chemical, petroleum, pharmaceutical, and mining.
This product is not a simple modification of an ordinary hydraulic station; rather, it is a safe-type equipment that incorporates the explosion-proof concept from the very beginning of its design.
The core electrical components of the product (such as motors, control boxes, and solenoid valves) all adopt explosion-proof structures that comply with ATEX (2014/34/EU), IECEx, or Chinese GB3836 standards. Common explosion-proof ratings include Ex d IIB T4 to Ex d IIC T6, which can cover various explosive gas environments such as propane, ethylene, and hydrogen, as well as combustible dust environments (Ex tD). This means that the equipment housing can withstand internal explosions without being damaged, and can prevent internal flames and hot gases from igniting the external environment.
Explosion-proof motor: It is equipped with a fully enclosed fan-cooled (TEFC) explosion-proof motor. The casing is robust, and all mating surfaces have been precisely machined to ensure that any internal arcs or sparks are completely isolated.
Explosion-proof electrical control: The control circuit uses intrinsically safe (Ex i) or flameproof (Ex d) components to eliminate the risk of electric sparks at the source. The junction boxes, buttons, etc. all have a protection level of IP65 or higher, providing dust and water protection.
Mechanical and fluid safety: The system uses high-temperature-resistant and anti-wear hydraulic oil. The pipeline connections are treated for anti-static purposes, and it integrates mechanical safety valves, temperature sensors, liquid level alarms, etc., to provide multiple levels of protection.
Compact integrated structure: Adopting the "power pack" design, the pump, motor, valve group and oil tank are integrated together. The volume is reduced by up to 35% compared to the traditional decentralized system, significantly saving equipment installation space. It is particularly suitable for integration into automated production lines or mobile devices.

1. Safe and compliant, with complete qualifications: The product follows explosion-proof design standards throughout its entire process. Core components hold authoritative explosion-proof certifications and provide complete compliance documents to help you easily pass safety audits.
2. High reliability design: Key components are selected from internationally renowned brands. The system undergoes strict factory tests (such as pressure cycling tests, sealing tests, and electrical safety tests), and the average time between failures (MTBF) exceeds industry standards.
3. Energy-efficient and highly efficient: Utilizing high-efficiency motors and variable pump technology, it outputs flow and pressure as needed. Compared to traditional fixed-volume pump systems, it can save up to 20%-30% of energy.
4. Low noise and low heat: The optimized hydraulic circuit design and high-quality components significantly reduce system operating noise and oil temperature, improving the working environment and extending the lifespan of the oil and equipment.
5. Strong customization capability: We do not simply sell standard products. The engineering team can conduct in-depth customization based on your equipment layout, pressure and flow curves, control interfaces (such as PLC signals, fieldbus), providing a "turnkey" solution.
6. Full lifecycle service: From pre-project technical consultation, selection design, installation guidance, commissioning training, to later spare parts supply and maintenance, we offer one-stop service support.
Selecting an appropriate explosion-proof hydraulic station requires considering several factors:
1. Environmental confirmation: Clearly identify the explosive media (gas/dust) at the site, the area classification (Zone 0/1/2 or 20/21/22), and the temperature group.
2. Operating requirements: Determine the working pressure, flow rate, action cycle, and control accuracy required for the actuator.
3. Installation conditions: Evaluate the available installation space, environmental temperature, and power supply conditions (voltage, frequency).
4. Control integration: Specify the communication and control method with the upper computer (such as PLC).
