Applicable industries and equipment operating conditions of the product

1. Hydraulic system for construction machinery: Suitable for excavators, loaders, rollers, environmental sanitation equipment, and engineering auxiliary hydraulic devices, it efficiently intercepts metal debris and sediment impurities generated by equipment wear and tear, and purifies the return oil circuit for harsh outdoor conditions with high dust and impurities.

2. General industrial hydraulic station: suitable for injection molding machines, die-casting machines, machine tool hydraulic stations, and automation equipment oil circuit return oil filtration, stabilizing the cleanliness of the oil tank and reducing system carbon and sludge accumulation.

3. Metallurgical and mining heavy industry equipment: equipped with steel rolling equipment, mining machinery, and hydraulic conveying systems, to cope with high load and continuous operation conditions, continuously filter circulating impurities in the system, and protect core components such as hydraulic pumps, valve bodies, and oil cylinders.

4. Light industry and power auxiliary equipment: It can be used in papermaking machinery, general chemical hydraulic systems, and power plant lubrication hydraulic stations as a system end return oil filter to ensure clean oil circulation and improve system operation stability.

This 20 μm large dirt filter is mainly used for filtering the return oil terminal of hydraulic systems, intercepting impurities such as metal debris, oxidized oil sludge, suspended dust, and fine sediment in the oil circuit, continuously purifying the circulating hydraulic oil, effectively avoiding common faults such as oil circuit blockage, valve body jamming, abnormal wear of pump body, and high oil temperature, greatly reducing equipment failure rate and shutdown maintenance frequency.

Core competitive advantages of the product

1. With a large capacity for dirt collection, it is suitable for high pollution conditions: the deep glass fiber filtration structure has a much larger dirt capacity than ordinary filter elements, and has stronger anti blocking ability for harsh working conditions with multiple impurities in construction machinery, effectively extending the replacement cycle and reducing maintenance times.

2. Low pressure loss leads to high oil flow and smooth oil return: The filter material has excellent permeability, and the original pressure difference loss is extremely low, which will not cause problems such as poor oil return, high back pressure, and rapid oil temperature rise, and will not affect the overall working efficiency of the hydraulic system.

3. The structure is sturdy and durable, with strong impact resistance: a double-layer metal protective net and a thickened integrated skeleton, which can withstand frequent start stop and pressure fluctuation impacts of hydraulic systems. It is not easy to deform, damage or fail after long-term continuous use.

4. Sealed and stable without leakage: Special oil resistant sealing rubber ring, suitable for long-term oil immersion environment, not easy to age, swell, or deform. The return oil pipeline is tightly sealed to prevent internal and external leakage and oil leakage hazards.

5. 100% original factory compatible replacement: The overall appearance, installation interface, and assembly dimensions are completely aligned with the original Parker 937852Q filter element, without the need to modify the equipment, and can be directly disassembled and replaced, with zero adaptation error.

6. Clean filtration without secondary pollution: The entire process is formed by hot melt technology, without glue or fiber detachment. The oil filtration has high cleanliness, which can ensure the long-term stability of hydraulic system oil quality and extend the service life of hydraulic oil.

Core advantages of source factory substitution

1. Years of technological accumulation and mature process: Our factory has been focusing on the localization and replacement of imported filter elements for 15 years. We are proficient in the structure and production process of Parker return oil filter elements, accurately replicating the original factory's filtration efficiency and pollutant absorption capacity, and eliminating common problems such as small pollutant absorption, easy blockage, and false precision standards in market imitation filter elements.

2. High cost-effectiveness and significant cost reduction: Direct sales from the source factory eliminate the need for import agents and intermediaries to increase prices. The product price is only about one-third of the original imported price, making it very suitable for bulk maintenance of engineering equipment, wholesale trade, and long-term factory support.

3. Quality control throughout the entire process: equipped with professional production and testing equipment, standardized production for each process, factory certificates for each batch of products, traceable quality, and worry free acceptance.

4. Flexible customization and adaptation to working conditions: We can customize exclusive filter cartridges according to customers' high temperature, corrosive media, special pressure, and non-standard size requirements, and adapt to various special equipment and complex operating conditions.

5. Improve the after-sales guarantee system: Strictly screen products before leaving the factory, eliminate defective products, provide one-on-one technical guidance on selection, installation, and working condition adaptation, and ensure worry free customer use throughout the process.

Frequently Asked Questions (FAQ)

Q1: Where is the 20 μm filter mainly suitable for use and what is the filtering effect?

A: 20 μm belongs to the industrial general precision filtration, mainly used for filtering the return oil pipeline of hydraulic systems. It can efficiently intercept impurities such as metal debris, oil sludge, dust, and fine sediment, and is suitable for high pollution circulating oil circuits such as construction machinery and general hydraulic stations.
