Gearmotors for Mixers and Agitators

In industrial mixing and agitation applications, selecting the right gearmotor can make the difference between smooth, efficient operations and costly downtime. From pharmaceutical blending to food processing, chemical mixing to wastewater treatment, these applications demand precise torque control, reliable performance, and specialized environmental protections.

KEB America brings decades of German engineering expertise to this challenge, offering a comprehensive range of customizable gearmotors tailored to meet the demands of mixing and agitation equipment. Whether you’re dealing with high-viscosity materials, washdown requirements, or space constraints, understanding your gearmotor options is essential for optimizing both performance and total cost of ownership.

German Engineered, Local Assembly

KEB gearmotors combine German precision engineering with local assembly at our ISO 9001-certified Minnesota manufacturing facility, ensuring both quality and responsive service. Our product line includes flexible configurations across multiple gearbox types, gear ratios, and motor options.

Beyond standard specifications, we provide extensive customization capabilities including enhanced environmental protection, reinforced bearings for heavy-duty applications, and food-grade or pharmaceutical-grade paint finishes. This flexibility allows you to precisely match our gearmotors to your specific application requirements, delivering optimal performance and reliability.

KEB Gearmotor Configurations

KEB’s gearmotor line features five distinct gearing technologies to address diverse mixing and agitation challenges. While parallel shaft and right-angle helical bevel configurations are our most popular choices for these applications, we also manufacture helical inline, right-angle helical worm, and planetary gearing systems. Each design offers unique advantages that can be optimized for your specific mixing requirements.

Compact and Efficient Design

KEB gearmotors feature an integral design that delivers superior space efficiency compared to separate motor and gearbox assemblies. By pressing the high-speed pinion gear directly onto the motor shaft, we eliminate the need for additional couplings while maximizing your available installation space. This integrated approach also reduces potential failure points and maintenance requirements.

Flexible Output Options

Understanding that every mixing application has unique spatial and mechanical requirements, KEB offers three primary output configurations to optimize performance and installation efficiency.

Hollow Shaft Configuration

Our hollow shaft gearbox output accommodates direct mixer or agitator shaft integration, eliminating additional coupling hardware. Alternatively, it can be paired with solid shaft outputs for applications requiring different mounting configurations.

Right Angle Output

The high-efficiency helical bevel design provides optimal performance for mixing applications requiring right-angle power transmission. Available in both IE2 and IE3 efficiency ratings, these gearmotors deliver energy savings while maintaining precise torque control throughout your mixing process.

Parallel Shaft

Ideal for space-constrained installations, our parallel shaft configuration positions the output shaft along the motor’s backside, minimizing the overall footprint without compromising performance.

Motor Integration Flexibility

NEMA or IEC Compatibility. For applications with existing motor preferences, KEB offers standalone gearboxes with either NEMA or IEC input couplings. Our designs accommodate both AC induction and servo motor integration, providing maximum flexibility in system design.

Enhanced Performance Features

Reinforced Bearing Systems
Heavy-duty applications benefit from reinforced bearings on both drive and non-drive ends, significantly increasing overhung load capacity. This enhancement is particularly valuable for large motors handling substantial loads or high-speed, low-ratio applications.

Pressure Management
Optional breather valves prevent internal pressure and fluid buildup, extending bearing life and reducing maintenance requirements in demanding environments.

Global Power Compatibility

KEB gearmotors support diverse voltage and frequency requirements worldwide. North American customers typically specify 230V or 460V configurations, while we readily accommodate 208V, 500V, 575V, 690V, and custom voltage requirements for international applications.

Environmental Protection

Our environmental protection options include IP65 washdown-rated motors and food/pharmaceutical-grade paint finishes. These features make KEB gearmotors ideal for demanding food processing and pharmaceutical applications that require rigorous sanitation without full stainless steel construction.

KEB’s versatile gearmotor designs enable precise customization for your unique mixing and agitation requirements, ensuring optimal performance and long-term reliability.
