mud agitator schottel brands

Derrick mud agitators include an explosion-proof, “C” faced motor, reduction gearbox (helical-bevel gears for horizontal agitators or all helical gears for vertical units), impeller, and shaft with assembly bushings. Motors range from 5 to 30 HP and may be supplied in several power configurations.

Attaching the motor directly to the gearbox protects correct alignment that can increase bearing life and provides 95 percent efficiency in power transfer to the impeller. Using this superior design surpasses standard worm drive gear assemblies by 30 percent, allowing Derrick agitators to do the same work at far less horsepower. By unitizing the motor and gearbox, weight and space requirements are reduced. Horsepower, mechanical configuration, impeller diameter, and shaft length are customized to tank dimensions and maximum mud weights. Available horsepower ratings* are: 5, 7.5, 10, 15, 20, 25, and 30.

Our agitators feature the new dracomet coated corrosion resistant keyless coupling for easy installation and impeller adjustment. The units come complete with base plate, motor, gearbox, impeller, shaft & couplings.

The MAX2000® Agitator features a rugged cast iron gearbox that houses helical bevel gearing. The gear sets are precisely ground to prevent all but the slightest amount of backlash in the gear sets. This feature promotes longer life by eliminating the high impact forces generated when the unit is energized at start-up. Each helical bevel gear stage is 98% efficient. A typical worm gear set is only 85% efficient, since it loses most of its efficiency through the generation of heat.

Internal gears and bearings are lubricated with mineral oil. When the ambient temperature drops below 23ºF or rises above 140ºF, a synthetic lubricant should be substituted. A unique feature of the MAX2000® Agitator is the lower bearing, which can be maintained from the top of the tank. This feature eliminates the need for in-tank inspections of the lower bearing, and also provides a barrier of grease that can be expunged out the lower seal. The lower seals are arranged to accommodate the grease pocket and make for a four-tier layer of protection for the gearing. The end result means the lower bearing stays in contact with good, uncontaminated lubricant at all times. All four of these levels must be breached prior to loss of oil in the gearbox.
