Product Information

Introduction HMA series agitators are heavy-duty mechanical mixers for viscous fluids specially designed for seal type tanks. Several models are available to meet a variety of mixing needs. The naming convention for these models is: HMA-X where X = the horsepower of the unit. For example, HMA-20 is the 20 hp mud agitator for seal type tanks. Each HMA series agitator uses a pipe-spool shaft and impeller(s) to maintain a homogeneous mixture of liquids and solids within a tank. Impellers have contour blades (axial flow), and may be installed in multiple configurations to provide the desired results. The impeller shaft is suspended from and attached to the output shaft of the low-profile, skid-mounted gearbox. The gearbox uses a worm-worm gear drive system to reduce the rotational speed of the explosion-proof motor to drive the impeller(s). HMA series agitators are available in models ranging from 25 to 40 horsepower, and can be seal base unit or shaft seal units. Impellers range from 54 inches (1372 mm) diameter to 84 inches (2134 mm) diameter.

Unit description General description Each HMA consists of a shaft-mounted impeller, motor, gearbox, and mounting base. Electrical controls, special coatings, custom bases, and other options are available.

Motor The motors used on Brandt mud agitators are explosion proof, T-frame, three-phase electric motors directly coupled to the gearbox using a flexible coupling with a solid steel guard. Motors are available for most voltage/frequency requirements. Other electrical code styles and temperature ratings are also available.

Gearbox The gearbox is a triple reduction worm-worm gear drive, reducing the motor speed (900 rpm @ 60 Hz) to the agitator speed (30 rpm) in a single 30:1 reduction. The gearbox contains an output shaft, two seals, and four to six bearings in addition to the worm-worm gear. The bearings are spaced to minimize shaft vibration and deflection, and seals are readily obtainable standard sizes. Unlike many competing agitators, Brandt’s gearbox requires no manual lubrication of the bottom output bearing.

2

Mounting base The motor and gearbox are assembled on a common base with heavy grade fasteners. The base is sand blasted to white metal, primed with zinc, and finish coated with urethane. Special coatings are available as an option.

Impeller Impellers are contour blade style, and may be installed in multiple configurations to provide the desired results. Impellers range from 54 inches (1372 mm) to 84 inches (2134 mm) in diameter. Larger custom-designed blades and mixing systems are also available. See Chapter 8 to find the Brandt office nearest you. Impeller speed is 30 rpm for 60 Hz applications.

Contour-blade impellers On contour blade impellers (Figure 2-1), the blades are designed with a variable pitch reducing the horsepower requirements and inducing less shear to the mud. Contour blades move liquid downward to the bottom of the tank, along the tank bottom toward the tank walls, and then up the tank wall. All fluid in the tank is mixed continuously, and the same consistency is maintained in all parts of the tank. Field experience has confirmed that this design provides the most homogeneous mixture in the widest range of installations. Fluid agitation minimizes fluid control problems caused by inconsistent mixtures.

Figure 2-1. Contour blade impellers promote axial flow with less shear to the mud.

Impeller placement Contour blade impellers should be placed on the shaft so that the distance between the bottom of the tank and the lower edge of the blades is equal to .75 times the diameter of the impeller.

Impeller shaft HMA standard impeller shafts are manufactured of eight-inch pipe spools. The impeller shaft is coupled to the gearbox with a rigid coupling. Shaft length is determined by tank depth. When ordering impeller shafts, always specify the actual tank depth. Tank depth is defined as the distance from the bottom of the tank to where the agitator is mounted.

Gear reducer oil capacity

Gear reducer capacity is 16 gallons (61 liters).

Gear oil is extremely slippery and sticky. Gear reducers are most easily filled using a pump or pressurized lubrication gun. Be sure to dispose of used oil properly and clean area of any spilled oil after completing this procedure.

Routine maintenance checklist Your HMA-series unit is designed for years of dependable service with routine inspection and maintenance. Additional copies of this checklist should be placed close to the unit for quick reference.

Startup 1. Check oil level with agitator off: oil should be level with the bottom of the oil level hole. Do not overfill.

2. Impeller rotation: The impeller should rotate clockwise when viewed from top. 3. Oil fill/breather plug: plug must be clear of any obstruction to prevent pressure build-up and possible seal damage. 4. Agitator should operate with no vibration. 5. Check rubber insert on input shaft coupling for wear and cracks. 6. For optimal performance, change the oil after the first five days of operation.

Daily

6

1. Inspect for oil leaks. 2. Keep motors clean and ventilation opening clear of mud build-up or other debris. 3. Check impeller shaft coupling for proper make-up.

Periodic 1. Check oil level. 2. Grease the gearbox top bearing with the approved bearing grease (see the "Recommended greases" table on page 6-2) every 100 operating hours. About a 3/8 in (9mm) ball of grease is sufficient. Do not over lubricate.

3. Change oil (see the "Recommended oils" table on page 6-3) every 100 operating hours. 4. Lubricate motors every three months. Do not over grease.
