TF Series External Self-sealing Filters

The TF series external self-sealing filter is primarily an oil suction filter installed at the pump intake to protect hydraulic components from contamination. Its key features include a novel design that allows for easy external mounting on the hydraulic tank, a built-in self-sealing valve to prevent oil leakage during maintenance, and an integrated bypass valve and contamination indicator to enhance system reliability.

Key Features of TF Series External Self-sealing Filters

• Self-Sealing Valve: An internal valve automatically closes when the filter cover is unscrewed for maintenance, isolating the tank's oil circuit and preventing oil from flowing out, which makes element changes quick and clean.

• Versatile Installation: The filter can be mounted directly on the top, side, or bottom of the oil tank, with the filter head exposed outside the tank for convenient access.

• Bypass Valve: To prevent pump cavitation if the filter element becomes clogged, a bypass valve automatically opens when the vacuum pressure reaches 0.02 MPa.

• Contamination Indicator: A visual or electrical signal device alerts operators when the vacuum at the filter outlet reaches 0.018 MPa, indicating that the element needs cleaning or replacement.

• Filter Media: Standard media options include wire mesh strainers (e.g., 40 to 440 µm) or sintered elements (e.g., 0.5 to 90 µm), depending on the specific application and cleanliness requirements.

• Low Resistance: Designed for high oil flow capacity with minimal resistance to flow, which is crucial for protecting the pump's suction line.

The Green hydraulic pump manufacturing facility is a specialized industrial plant that focuses on producing hydraulic pumps and related components. These factories are equipped with advanced machinery and technology to fabricate high-quality pumps designed for a wide range of applications, from heavy equipment and machinery to automotive and industrial systems.

The production process typically involves precision engineering, where raw materials like metals and alloys are processed into pump components such as gears, pistons, cylinders, and seals. These parts are then assembled into fully functional hydraulic pumps, which are tested for performance and quality control to ensure reliability, efficiency, and durability under various working conditions.

Green Hydraulic's manufacturing facilities for hydraulic pumps maintain stringent quality standards, often adhering to international certifications, to meet the expectations of customers in industries such as construction, agriculture, automotive, and manufacturing.

All hydraulic pumps produced by Green Hydraulic have undergone compliance testing, ensuring their quality and reliability.

To meet the diverse needs of different industries, the green hydraulic offer customization options, such as specialized seals, materials, and pump configurations. These facilities often work closely with engineering teams to develop tailored solutions for specific applications, from high-pressure systems to low-flow, high-efficiency pumps.

Each pump undergoes a rigorous quality control process, where pressure tests and performance assessments are conducted to ensure that the pumps meet the required standards for flow rate, pressure capacity, and durability.
