Product Description
High-pressure filters are protective devices installed in the pressure lines of hydraulic systems. Designed specifically for high-pressure applications, they effectively trap contaminants in the hydraulic fluid, protecting pumps, valves, and servo components from wear and seizure.
Featuring a high-strength housing and precision filter elements, these filters are capable of withstanding high pressures, have a high dirt-holding capacity, and allow for online monitoring of pressure differentials. They are widely used in medium- and high-pressure hydraulic systems in construction machinery, metallurgical equipment, and other industries.
Key Features

• The housing is constructed from high-strength materials and is rated for pressures up to 32 MPa, making it suitable for medium- and high-pressure hydraulic systems.
• Equipped with high-precision filter elements, with optional filtration ratings ranging from 1 to 30 μm, it effectively traps contaminants to protect precision components such as pumps and valves.
• Optional differential pressure transmitters or bypass valves provide clogging alerts and pressure relief protection, ensuring continuous system operation.
• It supports various installation and connection methods (in-line, panel-mounted, or stacked installation; threaded or flanged connections), making it suitable for different system layouts.

Application

• Main pump outlets and high-pressure oil lines in construction and mining machinery.
• High-pressure servo and proportional control systems in metallurgical equipment and injection molding machines.
• Medium- and high-pressure hydraulic circuits in critical equipment for wind power, marine, and aerospace applications.
• Pressure lines in high-pressure hydraulic stations for industrial automation production lines and machine tools.

Product FAQ 

• How often should the filter element be replaced?
•  A: Replacement frequency depends on your system's duty cycle and fluid cleanliness levels. We recommend replacing elements based on the differential pressure indicator or during routine maintenance intervals (e.g., every 500-1000 operational hours).

• Can I use different filtration ratings? 
• A: Yes, we offer various filter element ratings (e.g., 5μm, 10μm, 20μm) to suit the specific cleanliness requirements of your valves and pumps.

• Are the filter elements compatible with synthetic hydraulic fluids?
• A: The standard filter media is compatible with most mineral oils. For specialized fire-resistant fluids, please consult our engineering team for custom element material options.
