Description
Operating principle and technical role of the anti-vortex plate
In industrial water supply systems, fire pump stations, or chemical storage tanks, vortex formation at the suction inlet is always a difficult problem for design engineers. When the water level in the tank drops, the rapid flow creates a vortex core that draws air into the pipeline, causing a drop in pump chamber pressure and loss of prime. The anti-vortex plate installed directly at the tank bottom suction port acts to break the vortex trajectory of the fluid flow. As a result, water is guided evenly into the pipe with a stable flow, keeping the pump impeller submerged and maintaining the design flow rate throughout the operation.
Design benefits when applying anti-vortex plates in storage tanks
Integrating this device provides significant advantages in terms of space optimization and the durability of the entire system:
- Optimizing the useful volume of the tank: Allows for a lower water level than usual without worrying about air cavitation, helping to reduce the construction size of the storage tank.
- Protecting pump equipment: Prevents dry running, minimizes noise and vibration, and extends the service life of the pump assembly.
- Reducing operating costs: Simple mechanical structure with no moving parts, so there are no periodic repair costs.

| Debris filter screen | Optional integration of stainless steel or galvanized steel mesh |
| Connection type | Flanged or threaded according to piping standards |
| Pre-shipment inspection | 100% pressure testing and visual inspection |
Guidelines for selecting and installing anti-vortex devices according to engineering standards
For the device to perform at its full capacity, engineers should note some key points during the construction and installation process:
- Accurately determine the nominal diameter of the suction pipe to choose the appropriate flange size, avoiding pressure loss.
- The distance from the bottom of the plate to the bottom of the tank must comply with technical recommendations to ensure water flows smoothly from all directions.
- Regularly clean the debris filter screen (if equipped) to avoid obstructing the flow into the system.

Frequently asked questions about anti-vortex plates
Why do fire protection (PCCC) water tanks need anti-vortex assemblies?
When the water level is low, the suction creates a funnel vortex that causes the pump to draw in air, reduces flow rate, and damages the pump. The anti-vortex plate breaks the vortex, helping the pump drain almost all the water in the tank.
How to choose the size of the anti-vortex plate?
The plate diameter is usually much larger than the suction pipe diameter and complies with fire protection design drawings. Tan Dat custom-fabricates according to your suction pipe DN and drawings.
What is the function of the anti-vortex plate in pump systems?
The anti-vortex plate helps prevent vortex formation when extracting liquids, ensures the pump is always fully primed, prevents damage, and maintains maximum operating efficiency.
What materials are used to manufacture anti-vortex plates?
Products are mainly manufactured from Stainless Steel 304 or Stainless Steel 316, or galvanized steel according to customer requirements.
Does Tan Dat Mechanical accept custom fabrication of anti-vortex plates according to specific dimensions?
Yes. Tan Dat accepts custom fabrication of dimensions, connection types, and materials according to the actual requirements of the project.
