Product Description

The WUXU series oil suction filter, often referred to simply as the WU series (or XU series), is a simple yet effective coarse filter primarily designed to be installed at the suction port of a hydraulic pump to protect it from large mechanical impurities.


Key Features of RFA series miniature direct return oil filters

  • Coarse Filtration: Designed for basic filtration of larger mechanical impurities, typically using durable stainless steel wire mesh as the filter medium.

  • Low Flow Resistance: Essential for suction line application, these filters offer minimal resistance (original pressure loss ≤0.01 MPa) to ensure the pump can draw oil efficiently and prevent cavitation.

  • Integrated Bypass Valve: Includes a bypass valve that automatically opens if the filter element becomes clogged or the oil is very viscous (e.g., during cold starts). The opening pressure is typically set at a vacuum of 0.02 MPa to prevent pump starvation.

  • Durable Construction: Often made with stainless steel wire mesh for the element and standard materials for the housing to ensure longevity and corrosion resistance.

  • Versatile Connection Types: Available with both pipe (threaded) and flange connections to suit various system configurations.

    Standardized Accuracy: Standard filtration accuracy ratings are typically 80, 100, or 180 micrometers (

    ), focusing on capturing large particles before they reach the pump


Application

  • Engineering and Construction Machinery:

    Hydraulic oil tank suction ports of heavy equipment such as excavators, cranes, bulldozers, and loaders. Provides basic pump protection in dusty and harsh working conditions.

  • Industrial Manufacturing and Machine Tools:

    Hydraulic stations of general machine tools, injection molding machines, die-casting machines, hydraulic presses, etc. Used to filter out large metal chips and impurities that may be generated during the production process.

  • Metallurgical Industry:

    Hydraulic systems of rolling mills and continuous casting machines in steel plants. Removes scale and solid particles from the oil in high-temperature and heavy-load environments.

  • Power Systems:

    Hydraulic control systems and lubrication oil systems of thermal power plants and hydropower stations. Ensures the cleanliness of the oil in the control actuators.

  • Agricultural Machinery:

    Hydraulic systems of agricultural equipment such as tractors and combine harvesters, filtering out soil, plant debris, and other impurities that may enter during field operations.

Packaging & Delivery

Filter are typically packaged securely to prevent damage during transit. The packaging includes:

Protective Wrapping: To safeguard the pump from environmental damage.

Custom Crates: For larger, heavier pumps, ensuring safe handling.

Documentation: Includes installation, maintenance instructions, and warranty details.

Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.

Certifications & Quality Assurance

All Filter are manufactured in compliance with international standards, ensuring high performance and reliability:

ISO 9001: Certified for quality management systems.

CE Certification: Ensures compliance with European safety, health, and environmental protection standards.

RoHS Compliance: Ensures the pump does not contain hazardous materials.

Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.
