Description
Technical role of anti-vortex devices in water supply systems
In large-capacity storage tanks or industrial pumping stations, water discharge is often accompanied by vortex phenomena at the suction pipe inlet when the water level drops. This condition reduces supply flow, causes pressure drops, and allows air to enter the pipeline, leading to air binding, vibration, and pump overload.
The anti-vortex plate manufactured by Tan Dat is designed to eliminate the torque of the fluid flow before it enters the suction port. This accessory helps maintain a calm flow state, protecting mechanical equipment from the adverse effects of water hammer and cavitation.
Structure and practical operating principle
A standard anti-vortex suction unit consists of a flat or conical flow-blocking plate combined with a 90-degree flanged elbow. The operating mechanism is based on breaking the natural circular motion of the fluid:
- Eliminating the vortex core: When the water level drops near the bottom, the blocking plate stops the funnel-shaped vortex from the surface, preventing air from being sucked directly into the pipe.
- Stabilizing flow velocity: The distance between the plate and the pipe mouth is calculated to avoid obstructing the main flow, keeping the pressure at the suction port stable.
- Flexible installation position: The device effectively serves both configurations: positive head or suction lift systems.

Notes on selecting and installing anti-vortex suction units
For the device to maximize its efficiency, system engineers should note some important points during the pipeline design process:
- Determine the exact maximum flow rate of the pump to calculate the appropriate diameter of the blocking plate, avoiding bottlenecks that cause pressure loss.
- Ensure the minimum distance from the tank bottom to the underside of the plate so that water flows evenly from all directions.
- Use the correct flange standard (JIS, DIN, or ANSI) compatible with existing valves and piping systems.

Frequently asked questions about anti-vortex plates
Why do fire protection water tanks need an anti-vortex plate?
When the water level is low, the suction creates a funnel vortex causing the pump to draw in air, reducing flow rate and damaging 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 fabricates according to your suction pipe DN and drawings.
What is an anti-vortex device used for?
The anti-vortex device helps prevent the formation of vortexes when withdrawing liquids from tanks, maintains a stable flow, and prevents air from entering the pump system.
What material is used to manufacture the anti-vortex plate?
The product is made of standard Stainless Steel 304 and can use Stainless Steel 316 according to the customer's specific requirements.
Does the anti-vortex device support custom fabrication according to specific sizes?
Yes, Tan Dat accepts custom fabrication for sizes, materials, and flange connection types (PN16, JIS 10K, ANSI 150) according to drawing requirements.
