Detailed introduction of product materials
Our factory's PI23004DNSMX10 replacement filter element is benchmarked against the original PS filter material material system. We have strengthened the structure to address pressure fluctuations in the medium pressure pipeline, avoiding common problems such as cracking of the filter material, flattening of the skeleton, and delamination of the end cap in ordinary low-end replacement filter cartridges. The material configurations for each part are as follows:
-Filter material: multi-layer composite resin cured gradient glass fiber, outer layer coarse filter captures large particle impurities, inner layer completes 10 μ m precision filtration. The filter material has undergone high-temperature curing treatment, and the fibers are firmly bonded. Under the medium pressure pulse brush, the fibers do not fall off or the medium does not fall off. It has excellent dirt holding capacity and can effectively avoid secondary pollution in the oil circuit. It is suitable for long-term continuous operation of equipment.
-Internal and External Support Skeleton: Thickened galvanized punched metal skeleton enhances the anti extrusion ability for medium pressure conditions, resists the pressure difference impact caused by pressure fluctuations, and prevents the filter element from collapsing and deforming; High porosity of the skeleton reduces oil flow resistance and enhances oil flow capacity.
-Sealing rubber ring: standard NBR nitrile rubber sealing ring, oil resistant and anti-aging, tight end sealing, to prevent medium leakage and air intake under medium pressure conditions; FKM fluororubber seals can be upgraded as needed for high-temperature and corrosive media.
-End cap structure: Precision stamped metal end cap, using hot pressing composite bonding process. The bonding strength between the filter material and the end cap is high, resisting fluid impact and not easy to peel off. The installation and positioning dimensions are precise, perfectly matching the original filter housing.
Main applicable scenarios and industries
PI23004DNSMX10 belongs to the medium pressure pipeline filter element, which is different from the low-pressure double return oil filter element. It is mainly used in the medium pressure filtration circuit downstream of the pump and at the front end of the valve group. Its core application industries and equipment scenarios are:
-Machine tool equipment industry: large machining center hydraulic station, CNC equipment oil supply pipeline filtration, protection servo control circuit
-Metallurgical industry: steel plant auxiliary hydraulic system, continuous casting auxiliary medium pressure hydraulic pipeline impurity purification
-Power industry: Hydraulic systems for power plant auxiliary equipment, filtration of lubricating oil supply pipelines for generator sets
-General Heavy Industries: Injection molding unit hydraulic system, automation complete equipment medium pressure hydraulic circuit protection
-Industrial support: Equipment maintenance and project support for all MAHLE PI2300 series medium pressure filters
Core advantages of the product
Compared to ordinary cheap alternative filters on the market, this PI23004DNSMX10 filter is specially optimized for medium pressure pipeline conditions to solve various risks caused by pressure fluctuations in medium pressure environments
1. Strong anti pulse performance under medium pressure conditions: By strengthening the skeleton and combining it with cured fiberglass filter material, it can withstand the pressure impact caused by frequent pipeline start-up and shutdown, reducing the probability of filter material damage and filter deformation failure.
2. 10 μ m high-efficiency filtration, pre protection hydraulic components: intercept metal debris and oil sludge particles in advance in the medium pressure pipeline, reduce pump and valve wear, extend the overall service life of hydraulic components, and reduce downtime maintenance losses.
3. Gradient pollution absorption design to delay filter clogging: Multi layer composite filter materials are layered to contain pollutants, which will not quickly increase the pressure difference due to impurity accumulation, effectively prolonging the service life of the filter element and reducing the frequency of equipment replacement.
4. Completely interchangeable in situ, convenient operation and maintenance: 1:1 replica of original size and sealed interface, direct disassembly and replacement on site, no need for any modification of pipelines and filter housings, reducing on-site operation and maintenance workload.
5. Good stability of filter material, avoiding secondary pollution: High temperature cured fiberglass filter material, no free fibers falling off due to oil flow flushing, no new impurities entering the hydraulic system, ensuring the cleanliness index of the oil.
Core advantages of source factory substitution
Our factory has mature domestic production experience in the full range of PI filter elements, and has established a special testing process for the PI2300 medium pressure series. Compared with trading sources, we have multiple advantages:
-Benchmarking with original DIN standards, complete testing process: Referring to the MAHLE PI2300 series technical manual, production is carried out in accordance with ISO16889 and ISO2941 standards. Each batch is sampled for pressure resistance, sealing, and filtration efficiency testing to ensure product reliability under medium pressure conditions.
-Factory direct supply, controllable procurement costs: eliminating the premium of imported brands, procurement costs far lower than original parts, suitable for annual factory maintenance and bulk bidding procurement of engineering projects.
-Full process quality control, traceable quality: raw material inspection upon arrival, production process inspection, finished product sampling upon delivery, and key medium pressure filter cartridges can be provided with factory inspection data as needed.
-Support customization: Materials can be customized for high temperature and special medium conditions.
Frequently asked questions
