Automatic Backwash Suction Water Strainer Filters

Champion Suction Water Filters are designed for continuous removal of suspended particles from all types of liquids.

Major Applications are in industrial plants using river, lake, well or sea water for cooling, descaling, bearing lubrication, spraying, quenching, and similar purposes.

Pipeline sizes:from 2”NB to 48” NB.

· No Limitations on Flow rates.  

· No Limitations on Dirt Load.                    

· No Supervision required.

InstallationInstallation is made on the suction side of a pump or in any piping system operating under a positive pressure.  The strainer is compact with small face-to-face, width, and height dimensions. Installation can be made in a horizontal or vertical pipeline.

DesignThe strainer consists of a one-piece stainless steel cylindrical well screen drum with slotted openings ranging from .005" thru .075". Within the drum is contained a rotor, which is essentially a hollow rotating shaft- supporting two pads extended on each side. These pads are flush with the inside of the drum surface.

OperationThe liquid to be strained enters the inlet connection located in the lower portion of the body and flows upward into the inner surface of the drum. The suspended particles are retained in the media and the clean liquid passes through the media- leaving the body at the outlet connection located diametrically opposite the inlet.

BackwashAs the rotor sweeps past the straining media, a reversal of flow occurs, flushing the suspended particles from the media into the rotor and out through the backwash opening. Filtered water is used to backwash the filter element

Automatic Backwash ControlIn lieu of a manually operated valve on the backwash outlet line, an automatic control can be furnished to permit intermittent back flushing. This control consists of a motor or pneumatic cylinder operated ball valve actuated by a timer or a pressure differential switch (or both).
