CMS Strainer Description Model CMS strainers are offered in capacities to 200 gallons per minute per unit; manifolding multiple units increases this capacity. The strainers are offered for Vertical installation and are available to 0.0006" degree of cleaning using Concord's own "POSI-CLEAN" elements. The CMS has a large screen area, providing more filtering surface than any other same size automatic strainer in the marketplace, equating a higher filter open area to inlet area ratio. This allows longer straining cycles and less backwash disposal and electrical usage. The CMS strainer is a fabricated, single body vessel with a single straining element and is designed as a fully automatic self-cleaning strainer. The vessel is available fabricated to ASME Code latest edition and addenda ("U" stamped) and National Board Registered, or built in general accordance to ASME Code without code stamp or registration. In Canada, it is available also with "CRN" registration as required by provincial codes. Inlet and outlet connections are on the sides. The debris laden fluid enters the large upper chamber where it slows down and heavier contaminants settle to the bottom. The fluid flows downward passing through the screen media and exits the strainer through the outlet nozzle. Contaminants gather on the inside of the straining element. The CMS strainer can perform self-cleaning without interruption of flow. These strainers are designed primarily for service where large quantities of debris must be removed. The CMS Strainer uses a pneumatic actuator to mechanically clean the straining element. The strainer is purged by starting the pneumatic drive and opening the purge drain valve. This purging mechanically cleans the filter media by driving particulate collected on the media to drain. The strainer utilizes system pressure, a percentage of system flow and a scraper to clean the straining element. The controls to accomplish this can be as simple as a toggle switch to start and stop the pneumatic plunger, and a manual ball valve to control the system backwash flow. The CMS straining element is a cylindrical, reverse wound and resistance welded wedgewire tube ("POSI-CLEAN") that is open at both ends. Flow during straining is from the inside to the outside of this straining element. The straining element is constructed for easy replacement. The pneumatic actuator and cleaning disc scrape the filter media surface, driving particles down to the large collection chamber where purging sends the concentrated solids to drain. CMS Control Systems Every CMS strainer is shipped completely assembled, ready to operate. A single pneumatic cylinder with scraper and manual ball valve for purging. Concord automatic controls are engineered and designed to allow for optimal performance and ease of operation. They are factory set and field adjustable so as to provide for a minimal loss of backwash liquid and provide total cleaning of the "POSI-CLEAN" element.
