Our Strainer is a self-cleaning strainer for continuous straining of liquids in closed systems.
Our Strainer removes debris from natural water sources such as sea water or river water. It can also be used to remove particles in process liquids.

There are two types of Self cleaning filters are available.

1) Scrapper Mechanism Type:- With Automated Control System monitoring the Strainer operation,cleaning is accomplished by an internal Scrapper Mechanism. When cartridge gap gets plugged up by impurities and the differential pressure reaches its pre-set value. Then PLC inspects the signal and sends out the indication. The gear motor drives the scraper and the particles or agglomerates are skimmed from the surface, thereby keeping the function of cartridge well and keeping the cartridge gap clean.

When the impurities at the bottom of the filter increases, the drain valve opens up and the impurities are emptied successfully, which makes the system pressure achieve normality. Because of well-set position and optimum scraping angle, the rotational scraper drains off the impurities from the filter with the help of the gear motor. This avoids the burden of taking apart the cartridge and washing it, which results into successful filtration of the medium.

The scraper system contains stator, PTFE scraper and spring, which are designed for automatic cleaning, and especially for the reasonable spring pressure, maximally reducing the cartridge’s abrasion.

2) Disc Type :- With Automated Control System monitoring the Strainer operation, cleaning is accomplished by a disc. This is operated by pneumatic cylinder. When cartridge gap gets plugged up by impurities and the differential pressure reaches its pre-set value. Then PLC inspects the signal and sends out the indication. A spring-loaded cleaning disc moves up and down inside the filter screen and removes collected contaminants. The filtrate flows from top to bottom, and from inside of the screen to outside. The contaminants that are collected on the screen are easily removed and evacuated to the collection chamber. On the down stroke, any remaining contaminants are driven downwards to the collection chamber while on the upstroke, the cleaning disc removes contaminants from the screen surface.
