The first reduction helical change gears are spline or taper hub mounted for easy removal and replacement. Removing the change gear cover provides direct access to the change gears without the need to disturb other internal parts or the motor. Second reduction spiral bevel gearing offers low wear for long service, and provides superior efficiency for right angle power transmission. • Magnetic drain plug is included as standard • Hardened helical gears precision hobbed and shaved to exact tolerances for proper contact and wear • Spiral bevel gearing is precision generated, matched, lapped,...

Shaft Seals Seal Mounting Shaft seals attach directly to the integral ANSI mounting flange on pedestal mounted agitators. All shaft seals are also available as auxiliary units with beam mounted gearbox. Shut Off Systems Optional shaft shut off systems allow seal change without the leakage of process fluid or pressure loss. Types of Seals A wide selection of shaft seals are available for closed tank processes. Field service technicians are readily available to help maintain your equipment as shown in this large chemical plant in the UK • Lip Seal The spring loaded elastomeric lip seal...

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...

Agitator Dimensions Case Size

Motor Dimensions Mounting Dimensions Case Size Agitator Dimensions Case Size © D imensions are for totally enclosed and explosion proof motors. ® Agitator output speed, shaft diameter and extension, impeller design and other optional features to suit application. ® Larger and smaller flanges available, however in most cases, the smaller than standard flange dictates on centerline bolt holes and studs. ® Varies per case and shaft diameter selection. Refer to certified assembly drawing for actual dimension.
