Mechanical / Hydraulic
All dimensions are shown in Inches (millimeter).
- Diameter: 8” for TM720 series elements, 4” for TM710.
- The document includes diagrams with further dimensions. See the official PDF for exact tabulated values and diagrams.
Operating Information
- All elements are wet tested.
- Elements are treated with a 1% by weight percent sodium bisulfite storage solution and then vacuum packed in oxygen barrier bags. Alternatively, they may be treated with tested feed water solution and then vacuum packed in oxygen barrier bags with deoxidant inside.
- For short-term storage, shipment, or system shutdown, it is recommended that elements be immersed in a protective solution containing 500 - 1,000 ppm of sodium bisulfite (food grade) dissolved in permeate.
- Permeate from the first hour of operation shall be discarded.
- The use of chemicals incompatible with the elements will void the Limited Warranty.
