Chemineer HS Turbine Agitators
HS Side-Entering Agitators offer the same ruggedness, dependability and simplicity of design found in our other
high-quality turbine agitators and mixers. At the heart of the HS Agitator is a right-angle drive exclusively engineered
for side-entering agitator service.
Chemineer ® HS Side-Entering Turbine Agitators work efficiently when a tank is too large for convenient installation
of a top-entering agitator, or where headroom is severely limited. Supporting a top-entering agitator on a large
tank is often far more expensive than the installation of a side-entering agitator. Long shafts on extremely tall
tanks can be eliminated for cost savings and design simplicity. For large tank installations, several smaller side-entering
agitators may be more efficient and economical than a single, larger unit.
The HS Agitator is available in four standard sizes from 1 to 75 hp. Special designs, up to 250 hp, are available.
The wide range of power selections and seal options, combined with two standard output speeds and accurately sized
impellers, means that there is an HS agitator available for nearly every standard application. Consider HS Side-Entering
Agitators for process applications involving continuous blending, heat transfer, mass transfer or solids suspension.
Drive Elements
Right-Angle Design
The right-angle gear design of the HS Agitator reduces overhung load and minimizes nozzle reinforcement requirements.
A structural steel support leg is standard on HS Agitators with optional adjustable tie-rods available.
Spiral Bevel Gearing
HS drives utilize hardened spiral bevel gearing sized to provide heavy-duty performance and strength. All gears
are load-rated per AGMA standards and inspected to AGMA Quality 10 levels.
High-Capacity Tapered Roller Bearings
Rated at a minimum of 30,000 -hour L10 bearing life, the Timken ® high-capacity, tapered roller bearings throughout
the HS drive provide long service life and exceptional wear
resistance.
Positive Lubrication
All gears and bearings in the HS drive are splash-lubricated by an exclusive system developed by Chemineer. Double
lip seals on the drive shaft prevents oil loss or the infiltration of contaminants.
Extra Capacity Reducer Shaft
Due to a large cross-section, the low-speed shaft inside the drive minimizes gear misalignment and deflection. The
extension shaft is also designed to minimize deflection for superior seal life. Shafts are stocked in carbon steel
as well as types 304 and 316 stainless steel. Machinable alloys are also available to address an even wider array
of applications.
Motor Types and Mounting
For installation flexibility and easy mounting, the HS Agitator is compatible with standard foot-mounted electric
motors ranging from 1 to 75 hp. Vertical adjusting screws permit precise alignment of the motor even when the agitator
is mounted on the tank. Readily available, standard couplings reduce costs and replacement difficulties.
Rugged Steel Construction
Drive housings, support pedestals and mounting feet are fabricated from steel plate using high-tech NC machining
equipment. Each component must then pass a quality inspection on a computerized precision coordinate measuring inspection
machine. Each housing features lifting lugs and eyebolts for simplified, safe handling of the agitator during installation
and removal. Catalyzed, polyurethane exterior finishes protect against corrosion in both indoor and outdoor operating
environments.
Tank Shut-Off System
A retracting mechanism and seal shut-off are standard on all HS Agitators. This permits the replacement of cartridge
mechanical seals or the repacking of stuffing boxes without emptying the tank.
The mechanical seal shut-off is engaged when the easily accessible retraction bolt pulls the shaft shut-off collar
back into the flange housing. The shut-off seal is provided by a fluoroelastomer O-ring. The shaft is then rotated
to lock the extension shaft into the housing. This locking feature assures positive shut-off and shaft stability
during a mechanical seal change.
The stuffing box shut-off is accomplished by simply tightening the retraction bolt which pulls the shut-off collar
back and holds it securely. The seal is provided by a corrosion-resistant gasket sandwiched between the shut-off
collar and the mounting flange.
