brandt mud agitator parts supplier

The skid mounted MA-RG agitator is compact, and its low profile reduces headroom requirements and provides more layout space on top of the tanks. The gearbox is a triple-reduction helical-bevel gear drive system that reduces the rotational speed of the motor to drive the impeller(s). Up to 95% mechanical efficiency helps reduce horsepower requirements.

Impellers are available with flat blades (radial flow), contour blades (axial flow), and canted blades (radial/axial flow). The impellers are sized according to tank volume and expected duty. Active mud system compartments—such as solids removal sections, mud mixing sections, and slug pits, which need a higher shear force to produce immediate mixing—are another consideration in impeller sizing.

Several models are available to meet a variety of mixing needs. The naming convention for these models is: MA-XRGwhere X = the horsepower of the unit, and RG indicates the helical-bevel gearbox. For example, MA-20RG is the 20 hp mud agitator with a helical-bevel gearbox.MA-RG series agitators are very compact. Their low profile reduces headroom requirements and provides more layout space on top of the tanks. The 1:1 height-to-width ratio results in a lower center of gravity, providing stability and safety should the impeller encounter a sudden shock load.MA-RG series agitators use a regular mounting skid. NOV Brandt also offers an even lower profile version of the MA-RG series agitator, in which a base plate is used instead of the mounting skid to reduce the overall height. The naming convention for the agitator with base plate is: MA-XRGLPAnother variation of the MA-RG series agitators has a C-face motor with a gearbox coupling style. This variation also has a base plate instead of a mounting skid and is called: MA-XRGCFor example, the MA-3RGC is the 3 hp mud agitator with a helical-bevel gearbox and a C-face motor.Each MA-RG agitator uses a shaft-mounted impeller to maintain a homogeneous mixture of liquids and solids within a tank. Impellers are available with flat blades (radial flow), contour blades (axial flow), and canted blades (radial/axial flow). Blades may be installed in single or multiple configurations to provide the desired results. The impeller shaft is suspended from and attached to the output shaft of the skid-mounted gearbox. The gearbox uses a helical-bevel gear drive system to reduce the rotational speed of the explosion-proof motor to drive the impeller(s).2 Product Information2-2 NOV BrandtM14030 R3 Unit descriptionEach MA-RG agitator consists of a shaft-mounted impeller, motor, gearbox, and mounting base. Electrical controls, special coatings, custom bases, and other options are available.MotorThe motors used on NOV 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. GearboxThe gearbox is a triple-reduction helical-bevel gear drive, reducing the motor speed (1800 rpm @ 60 Hz / 1500 rpm @ 50 Hz) to the agitator speed (60 rpm / 50 rpm respectively) in a 30:1 nominal reduction. The gearbox contains an output shaft, two seals, and four to six bearings in addition to the helical-bevel gear system. The bearings are generously spaced to minimize shaft vibration and deflection, and seals are readily obtainable standard sizes.Mounting baseThe 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 epoxy. Special coatings are available as an option.Nominal ratingsVolts Hz RPM230/460 60 1800190/380 50 1500 2MA-RG Series 2-3M14030 R3 Product InformationImpellerImpellers may have flat blades (radial flow), contour blades (axial flow), or canted blades (both radial and axial flow). Blades may be installed in either single or multiple configurations to provide the desired results.Impellers range from 32 to 64 in (813 to 1626 mm) in diameter for canted and flat blades and 20 to 64 in (508 to 1626 mm) in diameter for contour blades. Flat-blade impellers are recommended for tanks less than 5 ft (1.5 m) in depth. Use canted or contour blades in tanks deeper than 5 ft (1.5 m). You may also mount a combination of types on a single shaft in tanks deeper than 15 ft (4.5 m).Larger custom-designed blades and mixing systems are also available. See Chapter 8 to locate the NOV Brandt office nearest you.Impeller speed is 57.5 rpm for 60 Hz applications and 48 rpm for 50 Hz applications.Impeller measurements DiameterCanted and flat weightContourweightin mm lb kg lb kg20 508 15 7 18 824 610 21 10 24 1128 711 33 15 35 1632 813 50 29 43 2034 864 NA NA 51 2336 914 79 36 58 2638 965 NA NA 83 3840 1016 101 46 NA NA42 1067 103 47 103 4644 1118 122 55 NA NA45 1143 NA NA 146 6648 1219 118 54 161 7352 1321 126 57 190 8654 1372 NA NA 195 8856 1422 NA NA 204 9360 1524 NA NA 214 9764 1626 NA NA 224 1022 Product Information2-4 NOV BrandtM14030 R3 Flat-blade impellersFlat blade impellers (see Figure 2-1) are recommended for tanks less than 5 ft (1.5 m) deep. When properly mounted, these impellers produce adequate agitation in these tanks, but may require baffles to induce both axial and radial flow and to minimize solids settling. Flat blades do the best job of preventing solids from settling on the tank bottom. Figure 2-1. Flat blade impellers promote radial flow in shallow tanks.Canted-blade impellersOn canted blade impellers (see Figure 2-2), the blades are angled downward at 60 to promote axial as well as radial flow. Canted blades shear and circulate to provide quick mixing. Vortexing may occur with canted blades.Figure 2-2. Canted blade impellers promote axial flow within a tank. 2MA-RG Series 2-5M14030 R3 Product InformationContour-blade impellersOn contour blade impellers (see Figure 2-3) 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. Contour blades also use less horsepower than canted blades.Figure 2-3. Contour blade impellers promote axial flow with less shear to the mud.Multiple impellersWhen an agitator is used in an extremely deep tank, over 15 ft (4.5 m) deep, multiple impellers can be mounted on one shaft. Usually the upper impeller(s) is a canted or contour blade, and the bottom impeller is a flat blade. Contact NOV Brandt engineering for proper impeller sizing and stabilizer requirements. See Chapter 8 to locate the NOV Brandt office nearest you.Impeller placementFlat-blade impellers should be placed 6 in (152 mm) above the bottom of the tank or 2 in (51 mm) above the bottom shaft stabilizer if one is used.Canted and 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 0.75 times the diameter of the impeller.2 Product Information2-6 NOV BrandtM14030 R3 Impeller shaftStandard impeller shafts for MA-RG series agitators are manufactured of solid mild steel. The impeller shaft is coupled to the gearbox with a rigid coupling. All shafts are keyed to adjust the height of the impeller. Bottom shaft stabilizerA bottom shaft stabilizer is required in deep tanks to reduce side loading on the gearbox bearings. The stabilizer also protects the agitator shaft and impeller when auxiliary equipment is carried inside the mud tank during rig moves. Bottom shaft stabilizers are required when the tank depth is 8 ft (2.4 m) or more.OptionsThere are several options available for MA-RG series agitators. Popular options include special paint finishes, remote starters, other electrical controls, and special duty motors. Contact your NOV Brandt sales representative to discuss which options may be right for your application. See Chapter 8 to locate the NOV Brandt office nearest you.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.Impeller shaft measurements ModelsStandard MetricDiameterin Weightlb/ftDiametermm Weightkg/mMA-3RGC 1.75 8.2 44.5 12.2MA-5RGC 2.375 15.1 60.3 22.5MA-10RG 3 24 76.2 35.7MA-15RG 3 24 76.2 35.7MA-20RG 3.25 28.2 82.6 42MA-25RG 3.5 32.7 88.9 48.7MA-30RG 3.5 32.7 88.9 48.7MA-40RG 3.5 32.7 88.9 48.7 2MA-RG Series 2-7M14030 R3 Product InformationAvailable modelsMA-RG series agitators are available in several models, from 3 to 40 hp.

As an option, the base may be welded directly to the mounting surface.Proper electrical serviceCheck all electrical components for proper voltage, frequency, duty rating, and adherence to applicable electrical codes.Oil fill breatherThe MA-RG agitator ships with the oil fill breather cap installed on the gearbox.Impeller rotationThe impeller should rotate clockwise when viewed from above.If the impeller rotates in the wrong direction, switch any two lead wires at the starter controls or at the motor. To switch wires at the motor, refer to the wiring diagram on the MA-RG name plate or inside the junction box cover.Disconnect power to the electrical circuit before beginning any work on the electrical controls or motor rotation.Failure to do so may result in severe personal injury or death.3 Installation3-2 NOV BrandtM14030 R3 Impeller shaft alignmentCheck the impeller shaft coupling regularly for proper alignment. As shown in Figure 3-1, the impeller shaft should not touch any portion of the stabilizer (if installed) when the MA-RG agitator is not running.Figure 3-1. Impeller shaft alignmentLong term storageStore the MA-RG agitator in a cool, dry place.The MA-RG agitator is packaged to prevent corrosion for a period of 12 months if stored indoors. During shipping, all openings are covered or capped to protect the inside from dust, rust and moisture. Threaded connections, couplings and shafts are coated with corrosion inhibitor.If the equipment is to be subjected to prolonged shutdown or storage, take the following steps to ensure that the unit does not degrade during storage. Motors are shipped from the factory pre-lubricated. Rotate the shafts 30 revolutions once per month to keep the bearings in the motor and speed reducer lubricated. Place protective caps over all threads to further guard against contamination. Keep temperature as consistent as possible to prevent condensation. If the motor is equipped with space heaters, connect them to the appropriate voltage and frequency. If unit is stored for more than one year, add grease before start-up.Some contact between shaft and stabilizer is normal during operation, but immediately correct any hard striking.

Additional copies of this checklist should be placed close to the unit for quick reference.Startup1. 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.Daily1. 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.Periodic1. Check oil level.2. Grease the gearbox input bearing with the approved bearing grease (see the "Recommended greases" table on page 6-2) every 5000 operating hours.3. Change oil (see the "Recommended oils" table on page 6-2) every 10,000 operating hours.4. Lubricate motors every three months.Do not over lubricate.Do not over grease.6 Maintenance and Repair6-6 NOV BrandtM14030 R3 7MA-RG Series 7-1M14030 R3 Parts and DrawingsParts and DrawingsOne-year recommended spare partsRecommended spares are for typical operating conditions.
