drops for each strainer size are listed in Table 2. A plugged strainer may completely block flow resulting. in a strainer differential pressure equal to the dead-head pressure of the system pump, which could lead to damaged strainer components. To clear a plugged strainer, refer to the cleaning section.
Assembly 1. For perforated elements with mesh overlays or filter tubes, slide the overlay or filter tube over the top of the element until it is approximately centered on the element. 2. Install a sanitary gasket over the end of the strainer element and slide the strainer element into the housing. 3. Secure with a sanitary clamp. Cleaning* 1. Turn off and lock out any pumps and/or equipment connected to the strainer process line. 2. Ensure that all pressure has been relieved from the system the strainer is installed on. 3. Close any available blocking / isolation valves. 4. Disassemble the strainer by removing the end cap clamp and pulling the element out. Remove mesh overlay if present. 5. Use a hose to spray the insert off with water to remove loose debris. 6. Clean the insert using a clean-out-of-place (COP) parts washer or other automated system running at an
adequate temperature, chemical concentration, and amount of time to remove all soil residue. If automated cleaning is not available, manually clean soil residue off the element using a scrub device, water source, chemical and gloves. 7. Rinse with appropriate water supply and inspect all parts for cleanliness and damage. 8. Reassemble the strainer as described in the assembly section. *These are recommended cleaning instructions only. Follow any plant sanitation standard operating procedure (SSOP) that your facility may have in place. A tri-clamp cap can be attached to the strainer body, which can then be cleaned-in-place (CIP) if desired during COP of the strainer element. Maintenance During normal disassembly, cleaning, and reassembly, inspect the key areas of the strainer that may require maintenance: 1) Soil. Inspect for soil particulates or foreign matter caught in the element. Remove as necessary. 2) Tri-Clamp Gasket. Inspect for cuts, abrasions, tears, holes, deformity, or other visible damage. Replace as necessary or no longer than a recommended annual basis.
