7EC4889-1001k is a hydraulic oil filter element used in oil refineries or petrochemical industries.

 1. Product Attributes

- Type: Hydraulic oil filter element / Lubricating oil filter element

- Application: Primarily used to filter solid particles, impurities, and colloidal substances in hydraulic or lubrication systems, ensuring oil cleanliness and preventing equipment wear.

- Applicable Scenarios: Key units in oil refineries, such as hydrogenation unit circulating oil systems, compressor lubrication systems, hydraulic control mechanisms, etc.

 2. Technical Parameters (Typical Values) Due to slight differences in specific parameters between different brands (such as PALL, HYDAC, or domestic alternatives), this model typically meets the following standards:

- Filtration Accuracy: Typically between 10μm ~ 25μm (commonly 10 microns or 20 microns, depending on the original manufacturer's requirements). - Operating Pressure: Generally suitable for low to medium pressure hydraulic systems, with a pressure range of approximately 1.0 ~ 21.0 MPa (depending on the specific structure).

- Operating Temperature: -10℃ ~ +100℃ (depending on the sealing material).

- Sealing Material: Typically Nitrile butadiene rubber (NBR) or Fluororubber (FKM). Fluororubber is often used in refinery operations to withstand high temperatures and chemical media.

- Filter Media: Mostly glass fiber, offering high dirt-holding capacity and filtration efficiency.

- Structure: Typically a stainless steel metal frame, with end caps typically made of carbon steel or stainless steel.

3. Applicable Standards

These filter elements typically conform to the following international standards:

- ISO 2941 (Filter element burst resistance verification)

- ISO 2942 (Structural integrity verification)

- ISO 2943 (Material and fluid compatibility verification)

- ISO 16889 (Multi-pass performance testing to determine filtration accuracy and dirt holding capacity)
