Our plunger guarantee hardness and wear resistance, but it also boasts excellent corrosion resistance, allowing for seamless operation even in the harshest of environments. This exceptional durability significantly improves the service life of our pump, providing our customers with a reliable solution that minimizes maintenance and replacement costs.

To further enhance its longevity, our Triple Plunger Pump features advanced self-positioning technology. This technology ensures that the plunger is stressed evenly, reducing wear and tear on the seal and significantly extending its service life. This feature allows our customers to experience uninterrupted operation and lower downtime, resulting in increased productivity and enhanced efficiency.

We understand the importance of maintaining high pressure in industrial applications. Therefore, our pump is equipped with imported V-type packing in the stuffing box, guaranteeing reliable and consistent high pressure. This feature ensures that our pump delivers consistent performance, even in the most demanding and high-pressure conditions.

Environmental protection is at the core of our product design. The compact structure and horizontal layout of our Triple Plunger Pump ensure minimal footprint, making it easier to integrate into existing systems without requiring substantial space. Additionally, our pump operates with reduced noise levels, contributing to a healthier and more sustainable work environment.

Environmental protection   
High-pressure water cleaning does not produce dust, such as the use of sewage recovery system, sewage, sewage will be directly recycled. Water cleaning requires only 1/100 of the material treated by dry sandblasting compared to traditional dry sandblasting.
Cost effective   
High-pressure water cleaning operations are not affected by the weather, and only a small number of operators, greatly reducing labor costs. Equipment quantification, shorten the approach preparation time, corresponding to ship cleaning, shorten the ship docking time.
After cleaning, it is sucked and dried, and the primer can be sprayed directly without cleaning the surface.
It has little impact on other processes, and can be used for other types of work at the same time near the high-pressure water cleaning working area.
Health and safety   
There is no risk of silicosis or other respiratory diseases.
It eliminates the flying of sand and pollutants, and will not affect the health of surrounding staff.
The use of automated and semi-automated equipment greatly reduces the labor intensity of the staff.
Quality surface   
There are no foreign particles, will not wear and destroy the surface of the cleaned material, will not leave old dirt and coating.
Fine needle flow cleaning, cleaning more thoroughly than other methods. The cleaning surface is uniform, and the quality meets the requirements of international standards.
