HeroFilters Automatic Backwash Strainers
Champion Automatic Backwash Water Strainers are designed to work continuously for all applications of process water, cooling water, wash water, white water filtration.
In operation the liquid enters the body and flows through the element from inside to outside. Debris is collected on the internal surface of the wedge wire element.
The backwashing system is monitored by differential pressure or is timer controlled. Once the differential pressure exceeds the set limit, a geared motor rotates a very precisely placed internal suction arm inside the filter element and opens the drain valve. A tremendous suction pressure is created due to the difference of atmospheric pressure and internal working pressure. This powerful suction pressure is used to collect the dirt/debris on the internal surface of the filter screen and throws it out of the system at very high velocity. All this happens within few seconds and is completely online without any stoppage of flow.
A hollow, full flow backwash arm extending the full length of the screen element rotates slowly inside of the screen and is piped to atmosphere. The port shoe is in close proximity to the screen. When cleaning is required the automatic backwash valve opens the system to atmosphere, causing a high velocity reverse flow across the isolated section of the screen. Dirt and debris are flushed from this segment of the screen into the backwash arm and out of the strainer via the backwash piping. During the backwashing cycle the main flow is uninterrupted and continues to be strained in the normal manner.
An automatic control system consisting of an electrical panel, actuated valves and a differential pressure switch operates the strainer. The cleaning cycle is set to activate on a timed cycle with a differential pressure override to protect against system upset conditions. The control system will automatically close the backwash valve after the screen element is properly cleaned.
We specialise in custom built Automatic Backwash Filters and also do have some standard sizes. Filter Media is available right from 10 microns rating to 3000 microns and above. So let us know your exact application so we can offer you the best suitable & cost effective solution
