The model KRF is a truly customizable fabricated self-cleaning strainer designed for continuous backflush operation. Featuring a fabricated backwash arm and a single, replaceable element Wedgewire basket—both of stainless steel construction—the model KRF is designed to be unattended for extended periods of time. The large amount of open area allows intermittent backflush operation, thereby minimizing both operating costs and backwash effluent. The Wedgewire element features a reverse groove design that prevents lodging of debris in the element and creates a vortex during backflush for a more efficient backflush operation. The model KRF can be constructed from a variety of materials— from carbon steel to stainless steel to exotic alloys—or can be coated internally with fusion bonded epoxy finish, allowing it to handle any fluid. For a truly customizable strainer that can be designed for any application or budget, not limited by size and pressure, the KRF is the finest choice.
