Detailed introduction of product materials

MF1003P25NB adopts resin impregnated paper filter material, which is different from fiberglass filter elements. It focuses on high flux, high pollutant absorption, and high cost-effectiveness, and focuses on avoiding faults such as damage to low-end substitute filter materials, flattened skeleton, end cap detachment, and paper hydrolysis failure in the market.

-Filter material: resin impregnated thickened paper filter material, which has been cured and impregnated to have certain oil and hydrolysis resistance, increasing the total folding area of the filter material and adapting to high-pressure and high flow conditions. The outer layer prioritizes the interception of large abrasive particles and sludge, while the inner layer completes the interception of 25 μm particles; Paper filter materials have a large dirt holding capacity and low flow resistance, making them suitable for hydraulic systems with high impurity content; Not suitable for oil working conditions with high temperature and high water content. Impurities are trapped in the filter layer, delaying the increase in pressure difference and reducing the frequency of on-site replacement.

-Internal and External Support Skeleton: Thickened punched galvanized carbon steel bidirectional support skeleton enhances the overall anti extrusion ability, responds to the alternating pressure difference caused by the start stop of the high-pressure system, and prevents the filter element from being flattened and collapsed by the pressure difference. The high porosity design of the skeleton ensures high flux flow, reduces the initial pressure difference of the filter element, and does not add additional resistance to the hydraulic oil supply system.

-Sealing parts: NBR nitrile rubber sealing ring is standard configuration, which is oil resistant, anti-aging, and resistant to medium swelling, to ensure that the filter element and the filter seat fit tightly, and to prevent oil bypass short circuit. High temperature and special flame retardant medium working conditions, supporting the upgrade of FKM fluororubber seals.

-End caps and bonding process: Machining metal end caps, high-strength two-component adhesive hot pressing composite, firmly bonding filter materials, skeleton, and end caps. The adhesive strength has undergone cyclic pressure drop impact testing and will not peel or crack under high-pressure fluctuation environment; The assembly size is 1:1 compared to the original factory, ensuring smooth disassembly and positioning, and stable sealing surface adhesion.

Main applicable scenarios and industries

MF1003P25NB is a high-pressure pipeline filter located downstream of the oil pump and is not recommended for direct protection of high-precision components such as servo valves.

-Mining equipment industry: The pressure pipeline filtration of large-scale mining hydraulic equipment produces a large amount of impurities due to harsh mining conditions, and the high absorption paper filter material reduces maintenance frequency.

-Rubber and plastic machinery industry: High pressure filtration of large injection molding machines, extruder hydraulic stations, protection of oil pumps, and ordinary valve groups.

-Metallurgical auxiliary equipment industry: rolling mill auxiliary hydraulic system, non servo circuit oil purification.

-Construction machinery industry: High pressure oil circuit protection for large mobile hydraulic equipment.

-Power industry: Non precision control oil station pipeline filtration for power plant auxiliary equipment.

Core advantages of the product

1. Paper filter material with high flux design and low initial pressure difference: resin impregnated paper filter material has low flow resistance and is suitable for high-pressure and high flow hydraulic systems, without causing significant burden on system oil supply.

2. High pollutant holding capacity and reduced maintenance frequency: Paper filter materials have excellent pollutant holding capacity, and in the face of high impurity conditions, the pressure difference rises smoothly, reducing the frequency of filter element replacement and lowering the comprehensive cost of labor and spare parts.

3. Reinforced B-structure skeleton, resistant to alternating pressure impact: The bidirectional metal support skeleton has undergone pressure difference cycling testing to adapt to frequent pressure fluctuations during industrial site start-up and shutdown, reducing the risk of filter deformation and failure.

4. Used in conjunction with graded filtration to protect mainstream hydraulic components: effectively intercepting large particles of hard impurities, protecting oil pumps, oil cylinders, and ordinary valve groups; The servo point requires additional configuration of high-precision fiberglass filter cartridges.

Core advantages of source factory substitution

Our factory has mature batch manufacturing experience in the MP-FILTRI MF series of high-pressure filter cartridges. We have established a special factory inspection process for paper-based high-pressure filter cartridges, and conduct pressure resistance, sealing, and filtration efficiency verification for each batch of samples to control the risk of filter material damage and prevent unqualified products from flowing to industrial sites. Direct supply from the source manufacturer, cutting off the premium of imported brand intermediaries, supporting single sample machine testing, undertaking annual factory maintenance, and large-scale bidding and procurement for engineering projects. We can upgrade the sealing material according to the customer's on-site medium, temperature, and pressure conditions.

Frequently Asked Questions (FAQ)

Q1: How to choose between paper P filter material and fiberglass A filter material versions?

A: P is resin impregnated paper, with a large amount of dirt and high cost-effectiveness, suitable for ordinary heavy-duty circuits; A is made of fiberglass, which has better filtration accuracy and stability, and is suitable for working conditions with high requirements for oil cleanliness; The two have the same external dimensions and can be assembled interchangeably.

Q2: Can paper filters be used in hydraulic oil systems with high water content?

A: Not recommended. Excessive moisture content can accelerate the hydrolysis and damage of paper filter materials. Glass fiber filter material versions are preferred for moisture containing conditions.

Q3: Can the 25 μm paper filter be directly used to protect servo valves?

A: No, 25 μm can only intercept large particles of impurities. The servo valve protection must be paired with a 3-10 μm high-precision fiberglass filter element to implement a graded filtration scheme.

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

A: Our factory has a complete product line for oil filtration. In addition to MP‑FILTRI replacement filters, we also produce PALL, PARKER, and Leemin series hydraulic filters, which are matched with mobile oil filter machine and coalescence dehydration filters to achieve integrated filtration of oil impurities and water.

Q5: What other filtering categories does the factory produce?

A: The source manufacturer covers industrial oil filtration, industrial water filtration, natural gas filtration, air filtration, and can produce imported replacement filters, domestic standard filters, and complete sets of filtration equipment. It supplies to multiple industries such as power, metallurgy, chemical, and gas.
