Automatic self cleaning screen filter, 2 ½ inches – vertical

Description

The automatic self cleaning screen filter can be used for mechanical filtration, both industrial and irrigation systems.

130 filtration degree – recommended for the protection of pipes, pumps, irrigation systems.

Other filtration degrees – recommended for industries based on the consumers’ needs.

Most frequently used filtration degrees are 30, 50, 100, 130 and 200, but we can provide you with cartridges anywhere between 30 and 2000 microns.

Screen cartridge – recommended for wheel / drill water. Commonly used to remove sand.

Applications:

• Factories – processed water, water for food & beverage, bottled water (along with other equipment).
• Residential and commercial buildings; logistics halls.
• 1st or 2nd stage placed before other filtration systems, depending on the needs.
• Irrigations – agriculture, viticulture.

Working principle

Filter sections: 1- Dirty water inlet, 2-Clean water outlet, 3- Backwash dirty water outlet drainage, 4-Sieve internal kit (multilayer), 5-Collector kit (backwash water vacuuming channel ), 6-Turbine chamber.

Water enters the filter and passes through a multi-layer filter, then passes coarse sieve. Water continues to flow from fine filter to exit, creating a layer of pollution on the inner surface of the filter and this pollution creates pressure difference at inlet and outlet of the filter. Backwash begins when this pressure difference comes at a predetermined level. A specified pressure difference is reached, the backwash control unit opens the discharge valve. Atmospheric pressure in the discharge pipe creates a strong backwash. This flow returns the cleaning collector through the hydraulic turbine and drainage pipe after vacuuming the pollution in the inner surface of the filter by creating a vacuum effect at nozzles. 

Pressure decrease consists in the turbine part and piston drainage provides a linear motion to the cleaning collector. This rotation and linear motion provides absorption of the pollution layer in the inner surface of the filter by nozzles. When the process is completed, the cleaning collector automatically makes a second backwash and returns to its original position, so the back washing process is completed. During backwash filtering process continues. For efficient work of the system, during the backwash process inlet pressure must not be less than 2 Bar (29PSI).

Other information:

• Drain for purged water is required.
• There is no need to replace the cartridge.
