 VS/VSS Agitators

VS Agitators are designed to provide long service and trouble-free operation in demanding pulp and paper applications.

• A312 Impellers with extra-strength hub and heavy-duty, precision-shaped blades provide superior strength without excessive weight.
• Agitators feature a modular stuffing box designed for simple removal of all components and easy inspection and maintenance in pulp and paper applications.
• Modular design permits fast bearing replacement without agitator shaft removal.
• Bearing adaptor sleeve eliminates the possibility of wear on the shaft.
• Oversized bearings reduce maintenance costs and keep downtime to a minimum.
 
   
 VSA Pillowblock Agitators
For pulp and paper applications.


The VSA Pillowblock Agitator is designed for maximum efficiency in severe-duty pulp and paper stock applications.

• Oversized pillowblock bearings provided a minimum B-10 life of 200,000 hours.
• Stainless steel stuffing box is easy to assess and remove for quick maintenance.
• A312 impeller provides 30% more flow than other "high-efficiency" paperstock impellers.
• Can maintain consistency variations to +/- 0.1% under the most adverse conditions.
 
   
 RSE Series Side-Entering Mixers

RSE Mixers are designed for easy installation and high-efficiency operation, which means decreased start-up expense and fewer manholes per tank.

• Rugged shaft support design can withstand all fluid dynamic forces.
• Bearings greatly exceed AGMA requirements for durability and long service life.
• Shaft bearings are located outside the tank to prevent corrosion and contamination.
• Designed for easy maintenance.
 
   
 SXJ Series Side-Entering Mixers

• Maintains suspension levels in storage tanks.
• Choice of stuffing box or mechanical seal.
• Shut-off device permits mechanical seal change while the tank is full.
• Available in 1/3 to 3.5 HP.
 
   
 The LIGHTNIN RSE Is Both Compact And Heavy-Duty, For Economical, Dependable Service

Sizes to 75 HP, 50% Greater Flow

Our complete line of RSE Series mixers ranges from 1 to 75 HP. Each includes our energy-efficient A312 impeller for 50% greater blending capacity over conventional impellers. Installation costs are minimal and operating costs are reduced by 40%

In many cases this high efficiency means a smaller model or fewer units can do the job. And that means decreased installation expense and fewer manholes per tank.
 
   
 LIGHTNIN FGD Single Slurry Seal

Lightnin has successfully applied hundreds of Top and Side Entry agitators for flue gas desulfurization processes, from the very first FGD installation in the 1960's at the Lawrence Energy Center to today's modern power plants. Since the first installation, the Boiler Systems have advanced considerably from the multiple Absorber Towers per Boiler in the 1970's and 80's to today's systems with a single tower per Boiler, capable of operation for extended periods without shutdown.

The mechanical seal is designed to excel in a harsh FGD environment. Engineered to operate with no outside flush liquid to reduce your operating expenses, dependency and usage of plant water.

A-312 Impeller
This hydrofoil impeller is specifically designed for the requirements of flue gas desulfurization. This impeller generates a strong, focused discharge across the swept diameter that ensures good solid suspension and gas dispersion.

The optimum blade configuration also eliminates the formation of eddy currents on the trailing surface of the blade. This design feature greatly reduces erosion and increases blade life.
