What is a Suction Oil Filter Element

Filter MF-08 is a suction oil filter element, the hydraulic suction filter is a component at the suction end in hydraulic oil systems, its installation location is below the oil level in the tank. Usually used to intercept solid particles, colloidal substances and other pollutants in working media such as mineral oil, petrol, emulsions, water, and ethanol. To protect the hydraulic pump from damage and to keep the hydraulic system clean.

The filter media of suction filter element are usually made of stainless steel mesh or fiberglass, working precision 100-800μm or 1-30μm can be customized. Increase the filtration area by using pleated mesh structure. The installation location is usually on the side, top, or bottom of the oil tank, with the suction cylinder immersed in the oil
and its top end cover above the oil surface. And the working temperature is -25 ℃ ~ +250 ℃.


 

Features of Suction Oil Filter Element

1. Hydraulic suction filter has a multi-layer composite filtration structure, it can intercept large particles of impurities to prevent pump wear, and filter micron-sized pollutants to ensure oil cleanliness.

2. The suction oil filter element has large dirt holding capacity and low pressure differential, it can work continuously and stably under high flow conditions, and effectively extends the service life of hydraulic system, and reduces the risk of equipment faults and downtime caused by pollution.

3. Suction filter cartridge has high temperature and corrosion resistance, can adapt to different types of oil and harsh environments. It has great adaptability and durability. Some models also support washing and reuse, and the long-term operating costs can be reduced.

4.The structure design of suction oil filters balances sealing and flowability, the installation is convenient, and maintenance is simple.
 

The Difference Between Suction Oil Filter and Return Oil Filter

Install Position

►Suction oil filter element usually installed at the suction port of the oil pump, or below the oil level in the oil tank. Intercepts the impurities entering the oil pump directly.
►Return oil filter element usually installed at the end of the return oil pipeline, or on the top of the oil tank. Treats the polutants during system operating.
 

Filter Fuction

►Suction filter mainly filters large solid particles, to prevent them enter the oil pump, and protect the hydraulic system.
►Return filter mainly filters fine pollutants, such as metal powder and colloids generated during the system operation, to maintain the oil cleanliness.
 

Filter Media

►Suction oil filter mainly use stainless steel metal mesh or wire gap, to reduce flow resistance.
►Return oil filter mainly use fiberglass folding mesh, to increase the filtration efficiency.
 

Filtration Accuracy

►Suction oil filter element has a low precision requirement, usually at a range of 10-180μm.
►Return oil filter element has a higher filter precison, usually up to 1-10μm, to ensure the oil cleanliness of long standing.
 

Working Pressure

►The initial differential pressure of the suction filter element should be ≤0.003MPa, and the maximum differential pressure should be ≤0.02MPa, to avoid affecting the oil pump's suction capacity.
►The ultimate differential pressure of the return filter element should be 0.2-0.35MPa, and the working pressure should be below 1MPa. The impact of hydraulic shock on the filter element must be considered.
 

Flow selection coefficient‌

►The flow of the suction filter element is designed according to the maximum flow of the oil pump multiplied by 1.5-2 times, to satisfied the high flow rate requirement.
►The return oil filter element needs to be designed multiplied by 2-4 times of the peak flow of the system return oil, to cope with instantaneous high pressure flow.
