Less than 0.5" gap resulting from drop into mounting flange catcher bracket Seal Change Procedure The double mechanical seal cartridge is removed in four simple steps requiring no special tools or blocking: 1. Unbolt the spacer spool between the reducer output and agitator extension shaft. The extension shaft drops less than 0.5" into a catcher bracket in the mounting flange to support the shaft and impeller weight. 2. Remove spacer spool. 3. Remove tapered shaft coupling half located above the seal cartridge. 4. Unbolt and slide the entire seal assembly off the extension shaft. Benefits •...

Top entering HTN agitator with pedestal mounted arrangement Bottom entering HBN agitator with a double mechanical seal and independently mounted drive Shaft Design Both process and mechanical considerations determine shaft design. Shafts are sized to resist torsional loads and bending moments induced by hydraulic forces acting on the impeller, as well as to avoid excessive vibration due to coincidence of critical frequencies and operating speed. Shafting is straightened to tight tolerances—less than 0.003 inches total run out per foot of shaft length (0.25 mm per meter)—for long seal life...
