Manufactured through powder metallurgy high - temperature sintering, sintered filter cartridges feature high - strength structures and precise pore control. They effectively intercept particulate impurities in fluids, offering excellent durability and stable filtration performance, making them a reliable choice for fluid purification across multiple industries.
The metal powder filter element uses deep fine polypropylene or glass fiber membrane as the filter material. It has a large diameter of 6 inches /152mm, no central rod, unidirectional opening, and is specially designed with a liquid flow direction from the inside out to ensure that all pollutant particles are intercepted inside the filter element. The design of ultra-high flow rate significantly reduces the usage of filter elements and filters in applications with the same flow rate, greatly saving equipment investment costs and labor costs.
Inflow of Fluid to be Filtered: Gases or liquids containing particulate impurities enter the filtration area from the outside or one end of the cartridge.
Gradient Filtration and Interception: As the fluid passes through the cartridge, different - sized particles are filtered step by step according to the gradient pore structure inside. The large pores on the outer layer first intercept large particles, while the small pores on the inner layer further retain tiny particles, achieving fine filtration.
Output of Clean Fluid: The clean fluid after multi - layer filtration flows out from the inside or the other end of the cartridge and enters the subsequent usage process.
Cleaning and Maintenance: When the pressure difference increases to the set value (e.g., 0.1MPa) due to impurities intercepted by the cartridge, it can be cleaned using methods such as backwashing, ultrasonic cleaning, or chemical cleaning. If the performance cannot be restored after cleaning, the cartridge needs to be replaced.

How does the sintered filter cartridge achieve high - precision filtration?
By controlling the powder particle size, sintering temperature, and pressure, the pore size and distribution of the cartridge are precisely adjusted, enabling accurate interception of particles of different sizes.
Will the performance of the cartridge decline after cleaning?
Proper cleaning methods (such as backwashing and ultrasonic cleaning) can effectively restore the cartridge's flux. However, frequent cleaning may cause slight damage to the pore structure, and replacement should be evaluated after multiple cleanings.
Can it filter highly corrosive liquids?
Sintered filter cartridges made of corrosion - resistant materials (such as titanium alloy and ceramics) can withstand the filtration of highly corrosive liquids like aqua regia and concentrated sulfuric acid. It is necessary to select suitable materials according to the characteristics of the medium.
Sintered filter cartridges serve as crucial technical supports for fluid purification in industrial production and civil fields, thanks to their unique high - temperature sintering process, high - precision filtration performance, and wide environmental adaptability. Whether in the pharmaceutical industry with strict purity requirements or the new energy field with high stability demands, efficient filtration can be achieved through customized selection and scientific maintenance. In the future, with the advancement of materials science and manufacturing processes, sintered filter cartridges will further enhance their performance, providing high - quality and reliable filtration solutions for more industries.
