Kinney - AFW-1 - Automatic Self-Cleaning Strainer - Brochure

f) Light duty strainer, designed for continuous removal of suspend-ed particles from all types of liquids. Applications are in industrial plants using river, lake, well or sea water for cooling, descaling, bearing lubrication, spraying, quenching, and similar purposes. Pipeline sizes: 2"- 48" Liquids other than water, such as chemicals, acids, white water (paper mills) , sewage plants, and ammonia flushing liquor (coke plants) can also be strained. INSTALLATION Installation is made on the discharge side of a pump or in any piping system operating under a positive pressure. The minimum working pressure required to effectively clean the straining media is 20 psi. The strainer is compact with small face-to-face, width, and height dimensions. Installation can be made in a horizontal or vertical pipeline. DESIGN Similar to many of the automatic strainers on the market, this design 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. OPERATION The 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. BACKWASH As 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. This reversal of flow is caused by a pressure differential between the interior of the strainer and atmosphere. The backwash flow rate is excep-tionally low and will vary, depending on the amount of suspend-ed particles in the liquid. The backwash piping should discharge downward into an open funnel immediately after the backwash valve. AUTOMATIC BACKWASH CONTROL In lieu of a manually operated valve on the backwash outlet line, an automatic control can be furnished to permit intermittent backflushing. This control consists of a motor or pneumatic cylinder-operated ball valve actuated by a timer or a pressure differential switch (or both). S.P.
