V2.1217-56 V2.1234-28 V7.0820-58 Hydraulic Return Oil Filter – Replacement Excavator Concrete Pump
The quality of hydraulic oil is crucial for the operation of hydraulic systems, and its quality directly affects the system's performance. Many fault problems can be traced back to the quality of hydraulic oil. In order to maintain the cleanliness of the oil and prevent contamination, installing a hydraulic oil filter is an indispensable step. It can effectively intercept and remove pollutants in the oil, ensuring the stable operation of the hydraulic system.
Hydraulic oil filters play a critical role in hydraulic systems, used to filter impurities from hydraulic oil. These impurities come from various sources, including residual mechanical impurities after cleaning, dust entering the system from the outside, and metal powder generated during system operation. If these impurities are mixed into hydraulic oil, they will spread everywhere with the circulation of the oil, causing serious impact on the normal operation of the hydraulic system.
Efficient filtering capability
The hydraulic oil filter element adopts high-precision filter materials (such as glass fiber, metal mesh, etc.), which can intercept micron sized particles (usually up to 1-10 μ m), effectively preventing impurities from entering precision components such as hydraulic pumps, valve groups, or motors, significantly reducing the risk of wear and extending equipment life.
Long service life
The filter material of high-quality filter cartridges has undergone special treatment (such as corrosion resistance and high temperature resistance), combined with reasonable structural design (such as multi-stage filtration and large dust holding capacity), and can withstand high pressure and frequent impact, with a service life far exceeding that of ordinary filter cartridges.
Low flow resistance design
The filter element adopts a gradient aperture or a three-dimensional folding structure inside, which ensures filtration accuracy while minimizing the resistance of hydraulic oil passing through. Low flow resistance can reduce system energy loss and improve hydraulic pump efficiency, especially suitable for high-pressure and high flow scenarios, with significant energy-saving effects.
Strong compatibility
The hydraulic oil filter has complete specifications and can be adapted to different brands and models of hydraulic systems. Whether it is fixed equipment or mobile machinery, corresponding interfaces and sizes of filter cartridges can be found, reducing the difficulty of user selection.

Q1.Do you have MOQ?
Depends on different ideas, Can be negotiated.The larger the quantity is, the competitive the unit price will be.
Q2.Should the customer pay the delivery fee,How much is it?
For the delivery fee,many samples are be requested to be sent,so we must get delivery fee. If you tell me to use the appointed Express,you will give me your express account or you will pay according to the Express. If you do not request,I will choose a cheap one in China.
Q3.How about the after sale service?
1)We will always keep the quality the same as the buyer's samples and if there is something with the quality,we will make compensation for our customers.
2)We will suggest our packing and take charge in our packing,we will keep the goods safe in the delivery.
3)We will trace the goods from the production to selling,we will solve the problems in the selling for our customers.
Q4.When can I get a price?
We usually quote within 24 hours after we get your inquiry.
Q5: What are the materials of the filter element? What are the corresponding accuracy ranges?
According to the classification of filter materials, there are: oil filter paper: 10-50um, glass fiber: 1-70um, HV glass fiber: 3-40um, metal mesh: 3-500um, sintered felt: 5-70um, and line gap filter: 15-200um.
Q6: What brands of filter cartridges do you make?
Our factory produces alternative universal filter elements for foreign brands such as Pall, Hedek, Dasheng, Parker, and Rexroth, as well as national standard oil suction filter elements, oil return filter elements, high-pressure filter elements, and coalescence dehydration filter elements. We support non-standard customization. We welcome samples or drawings for processing and customization.
Q7: How can customers choose the appropriate filter size when making their own filters?
We need to provide the flow rate, pressure, external dimensions, accuracy, filter medium and other parameters of the filter designed by the customer. We will provide the customer with the selected filter element size and quantity based on the filter size.
Q8: Is there any difference between filtering kerosene, gasoline, diesel filters and general hydraulic oil filters?
The sealing materials used in the filter element are different. Generally, the sealing ring of hydraulic oil filter element is nitrile rubber, while filtering media such as kerosene, gasoline, and diesel requires the use of fluorine rubber rings.
