Overview
The VANVEO Glass Lined Frame Agitator is engineered for superior circulation and uniform blending in large-scale chemical processes. Unlike standard anchor types, the frame structure features additional horizontal supports, providing enhanced mechanical rigidity to move bulk fluid effectively in open-type glass lined reactors.
By applying premium high-silica glass enamel to a robust carbon steel core and firing, we create a stirrer that combines extreme corrosion resistance with the structural integrity required for continuous, heavy-duty operation.
Applications of Glass Lined Frame Agitator
Glass lined frame agitators are widely used in chemical reactors requiring stable circulation and uniform temperature distribution. They are particularly suitable for crystallization processes, slurry suspension mixing, polymer solutions, fertilizer production, and other medium-to-high viscosity applications.
The reinforced frame structure helps maintain consistent axial and radial flow inside large vessels, reducing dead zones and improving mixing efficiency during batch processing.
Key Features
Enhanced Structural Rigidity
Integrated frame with horizontal reinforcement prevents shaft deflection in large vessels.
Optimized Bulk Circulation
Promotes top-to-bottom fluid movement to eliminate temperature and concentration gradients.
Improved Heat Transfer Efficiency
Enhances fluid movement near reactor walls in jacketed vessels for better thermal uniformity and stable reaction conditions.
Gentle, Low-Shear Agitation
Ideal for shear-sensitive reactions, maintaining the integrity of delicate particles.
Superior Chemical Resistance
0.8–2.0 mm glass lining offers a smooth, non-stick surface against acids and alkalis.
Stable Heavy-Duty Operation
Symmetrical structure ensures smooth rotation and extends mechanical seal life.
Typical Applications
- Bulk fluid homogenization in large-volume chemical reactors
- Shear-sensitive processing for suspension and polymer systems
- Temperature stabilization in jacketed reactor vessels
- Large-scale synthesis requiring stable circulation and uniform blending
Frame Agitator vs Anchor Agitator
Although both frame agitators and anchor agitators are designed for low-speed mixing, their mixing functions are different.
Frame agitators are mainly used for bulk circulation and uniform blending in large-volume reactors. Their reinforced frame structure improves overall flow distribution and temperature consistency throughout the vessel.
Anchor agitators are more suitable for high-viscosity applications that require wall-scraping performance to prevent material buildup on reactor surfaces.
For processes involving crystallization, suspension mixing, or large-batch homogenization, frame agitators are often the preferred solution.
Design Advantages of Reinforced Frame Structure
The reinforced frame structure provides better mechanical stability during continuous operation in large reactors. Compared with simpler agitator designs, the frame configuration improves circulation near vessel walls and reduces uneven flow distribution.
This design is especially beneficial for temperature-sensitive chemical reactions and large-volume batch processes where mixing consistency is critical.

FAQ
Q1: When should I choose a Frame Agitator over an Anchor type?
Choose the Frame Agitator when your primary goal is bulk circulation or when the reactor volume is large. If your process involves high-viscosity wall-scraping to prevent buildup, the Anchor Agitator is more suitable.
Q2: Does the glass lining affect the mechanical strength of the frame?
No. The carbon steel core provides the necessary mechanical strength and torque resistance, while the glass lining acts as a protective shield against chemical attack.
Q3: What seal types are compatible with this agitator?
We offer both Single and Double Mechanical Seals to ensure vacuum-tight operation and prevent leakage of hazardous vapors.
Q4: What is a frame agitator used for in chemical reactors?
Frame agitators are commonly used for bulk circulation, suspension mixing, crystallization, and temperature-sensitive reactions in large-volume chemical reactors.
Q5: Can frame agitators improve heat transfer efficiency?
Yes. The frame structure increases fluid movement near reactor walls, helping improve heat transfer performance in jacketed vessels.
