MODEL 400 & 401 KNIGHT-WARE® Monolithic Chemical Stoneware Sumps
GENERAL NOTES: CONSTRUCTION Using a very stiff clay mix, these ceramic shells, complete with connections and dip pipe, are formed in one piece, carefully dried, then vitrified at a kiln temperature in excess of 2100°F. The end product is a dense acid-proof stoneware vessel, completely joint-free and inert to all chemicals except hydrofluoric acid and hot concentrated caustic. FOUNDATION The 400 and 401 Series ceramic sumps should be bedded in a thin layer of sand or fresh stone-free grout on firm base. Avoid possibility of point bearings such as pebbles, rocks, or hard debris under bottom. When filled with neutralizing fill and water, the larger sumps involve considerable weight. Provide even load bearing when using beam supports; possibly using thin grout or roofing paper insulation.
