MAHLE PI2105PS3 hydraulic oil filter element replaces 3um high-precision glass fiber rated flow 50L/min for small hydraulic stations

Core basic parameters of the product

The PI2105PS3 replacement filter element is manufactured according to the original design specifications of MAHLE, and has passed multiple performance tests according to ISO16889 standards. All parameters are interchangeable with the original filter cartridge, and the core technical indicators are as follows:

-Product model: PI2105PS3 (domestic substitute)

-Filtering accuracy: 5 μm, β (c) ≥ 200, achieving efficient interception of solid particulate pollutants

-Adaptation filter: MAHLE PI210 series low-pressure filter

-Applicable media: mineral lubricating oil, anti-wear hydraulic oil

-Maximum working pressure: 6.3MPa (63bar), suitable for low-pressure circulating filtration conditions

-Working temperature range: -10 ℃ to+120 ℃

-Bypass opening pressure difference: 3bar, bypass integrated filter base, filter body without bypass structure

-Suggest replacing the pressure difference: 0.2MPa. If the alarm pressure difference is reached, the filter element should be replaced in a timely manner

-Structural form: Fiberglass folding filter layer, equipped with metal support skeleton inside and outside, oil flow direction from outside to inside

Detailed introduction of product materials

In response to the long-term uninterrupted cyclic operation of the low-pressure lubrication system, the materials of each component have been optimized and selected to avoid faults such as filter material detachment, skeleton collapse, and end cap detachment of ordinary low-end replacement parts.

-Filter material: Multi layer gradient resin cured fiberglass filter material, with the outer layer intercepting large particle impurities and the inner layer completing 5 μm precision filtration. The filter material has undergone high-temperature curing treatment, and the fibers are firmly bonded. The fibers are not easily detached under oil flow erosion, preventing secondary pollution to the oil circuit. It has excellent dirt holding capacity and is suitable for lubrication stations that operate continuously for a long time.

-Internal and External Support Skeleton: Galvanized metal punched skeleton ensures the overall structural rigidity of the filter element, resists the compression caused by pressure difference changes, and avoids the collapse and failure of the filter element; The high porosity of the skeleton reduces overall flow resistance and ensures the circulation flow of lubricating oil.

-Sealing parts: standard NBR nitrile rubber sealing ring, oil resistant and anti-aging, reliable end face sealing, preventing leakage and air intake in the low-pressure circuit; FKM fluororubber seals can be upgraded for high temperatures or special media.

-End cap: Metal stamping end cap, using hot pressing composite bonding process, firmly bonding the filter material and end cap, precise positioning size, ensuring good matching with the filter housing cavity.

Main applicable scenarios and industries

PI2105PS3 belongs to the low-pressure lubrication circuit filter element, which is mainly used in lubrication stations and auxiliary hydraulic systems, and is not suitable for high-pressure pressure pipelines. Its main application scenarios are as follows:

-Power industry: auxiliary lubrication system for generator sets, auxiliary oil filtration device for steam turbines, to ensure the quality of lubricating oil and reduce bearing wear.

-Metallurgical industry: auxiliary lubrication station for rolling mills, low-pressure oil circulation filtration for continuous casting equipment, filtering metal debris and sludge generated by equipment operation.

-General Heavy Industries: Large gearbox lubrication system, complete equipment low-pressure hydraulic oil supply circuit, protecting gears and sliding bearing components.

-Industrial support: maintenance of various equipment equipped with MAHLE PI210 series filters, and spare parts support for new construction projects.

Core advantages of the product

1. Suitable for low-pressure continuous circulation conditions: The combination of filter material and skeleton optimizes the flow resistance, and in a 24-hour non-stop lubrication system, there will be no excessive initial pressure difference, ensuring stable oil supply.

2. 5 μm precision filtration, protecting vulnerable moving parts: effectively filtering out small metal particles, reducing abrasive wear of bearings and gears, extending equipment overhaul cycles, and reducing downtime losses.

3. High pollutant holding capacity, extended service life: Gradient layered filtration structure, pollutants can be distributed in different filter layers, slowing down the rate of pressure difference rise and reducing the frequency of filter element replacement.

4. Direct exchange, easy on-site operation and maintenance: Strictly replicate the original size and sealing structure, directly disassemble and replace on site, without any modification to the equipment, reducing the labor cost of spare parts replacement.

5. The material is stable and reliable, avoiding secondary pollution: the cured fiberglass filter material has no free fibers falling off, and will not introduce new impurities into the system, ensuring stable oil cleanliness.

Factory direct supply saves brand premium, suitable for large-scale maintenance and project procurement. Materials can be customized according to customer working conditions.

Frequently Asked Questions (FAQ)

Q1: Can the replacement produced filter element of PI2105PS3 be directly replaced with the original MAHLE parts?

A: It can be directly replaced in situ, and the size, sealing, accuracy, and pressure resistance parameters are all compared to the original, suitable for PI210 series low-pressure filters.

Q2: What is the reason for the rapid increase in filter pressure difference?

A: Most of them have high levels of internal pollutants in the system, and it is necessary to check the condition of the oil; Use a pressure difference of 0.2MPa as the basis for replacement, and do not rely solely on the running time for judgment.

Q3: Can seals be replaced with fluororubber?

A: Sure, for high temperature or special oil conditions, please indicate the requirement when placing the order to replace the FKM fluororubber seal ring.

Q4: Apart from MAHLE filter elements, what other oil filtration products do you have?

A: Our factory has a complete line of oil filtration products, which can meet the purification needs of industrial oil products under all working conditions. In addition to the full range of MAHLE replacement oil filters, we also specialize in PALL, HYDAC, Leemin and other full range oil filters and filters, matched with LYC-A series movable oil filters and oil coalescence dehydration filters, providing one-stop solutions for industrial oil impurity removal and water filtration problems.

Q5: What other filtering categories are included in the factory's main business?
