Venturi powder pumps are usually used in conjunction with spray guns, recovery devices and powder supply devices. Their function is to ensure that powder coating can be continuously and stably supplied to the spray gun, thereby achieving uniform coating coverage. At the same time, due to the high conveying efficiency and stability of the Venturi powder pump, it can significantly improve the production efficiency and coating quality of powder coating.
Main advantages
Efficient and stable: The Venturi powder pump is driven by the rotation of the impeller and the positive and negative pressure of the shell, which can achieve efficient powder delivery and stable coating coverage.
Easy to maintain: The structure of the Venturi powder pump is relatively simple, with fewer wearing parts, so the maintenance and replacement costs are low.
Strong adaptability: The Venturi powder pump can be applied to different types of powder coatings and coating process requirements, with high versatility and flexibility.

The new generation DDF4 powder pump invented by Ruisai Gaotingshi can operate friendly under the principle of high powder concentration and low air flow rate. Since 2001, DDF technology has proven to operate stably in long-term and harsh hot and humid environments. The fourth generation DDF4 powder pump can adapt to different types of powders and maintain a soft, smooth and stable powder delivery effect.
The latest DDF4 powder pump is user-friendly and easy to operate. There will be no powder spitting under different conveying distances and powder types. The rugged structure can meet the high-pressure cleaning requirements required for fast color change systems.
When compared with Venturi pumps/injectors, DDF4 can save a lot of compressed air.
The low powder delivery rate allows the powder particles to have a longer charging time (2.5X), thus forming a "soft spraying" effect and high charging efficiency for the powder.
Main advantages
Long-term stable powder delivery and excellent coating thickness control effect
Minimum production downtime
Fewer wearing parts, reducing the cost of use
Minimum compressed air usage leads to lower cost of use
Low powder delivery speed, bringing "flexible spraying" effect and high powder charging efficiency
