98 Series - High Torque Top Entering Mixer

Overview

The Lightnin 98 Series Mixer is engineered to handle high torque mixing applications while minimizing gear deflection and maximizing seal life. Its advanced design isolates internal gearing from fluid-induced forces, ensuring long-term reliability and performance in demanding industrial environments.

Gear Isolation Design Advantages

• Lower quill shaft bearing experiences no external loading
• Clearance between mixer and quill shafts prevents bending loads on gearing
• Fixed bearing in seal cartridge absorbs radial and axial forces
• Precise bearing placement minimizes shaft run-out and dynamic deflection

Mechanical & Operational Features

• Parallel shaft, double reduction design: Ideal for space-constrained installations
• Carburized and ground helical gearing: Quiet operation and extended gear life
• Dry well oil dam: Prevents lubrication leakage down the mixer shaft
• Integral positive displacement pump: Provides continuous lubrication without a separate motor
• Compact drive design: Requires less oil, eliminating the need for a large sump
• Forced lubrication system: Filters contaminants to extend oil life
• Standard flanged motors and pedestal mount: Simplifies assembly and eliminates high-speed coupling alignment
• Integral mounting plate: No need for additional bolted plates
• Optional seal cartridge: Easily removable in four steps without disturbing gear drive or shaft bearings

Specifications

• Power range: 15–130 kW (20–150 HP)
• AGMA speed range: 20–100 RPM
• Seal options: Open tank, stuffing box, or mechanical seal
