One of the standout features of our plunger pumps is the use of tungsten carbide material. With a hardness higher than HRA92, our plungers guarantee superior performance and durability. The surface accuracy, with a rating higher than 0.05Ra, ensures precision and smooth operation. Moreover, the straightness and cylindricity less than 0.01mm further enhance the efficiency and effectiveness of our pumps.But that’s not all. Our plungers not only offer exceptional hardness and wear resistance but also provide excellent corrosion resistance. This unique combination ensures a longer service life, reducing the need for frequent replacements and maintenance. No matter how intense the working conditions, our pumps will stand the test of time.To further enhance durability, we have incorporated a plunger self-positioning technology. This advanced feature guarantees even distribution of stress on the plunger, prolonging the lifespan of the seal. With our technology, you can be confident that our pumps will operate flawlessly, delivering uninterrupted performance even in the harshest environments.The stuffing box plays a crucial role in maintaining the optimal performance of our pumps. That’s why we have equipped it with imported V-type packing. This highly reliable and efficient packing ensures that the high-pressure generated by our pumps is contained securely, preventing any leaks or malfunctions. You can rely on our pumping system to consistently perform at its best.

Our ultra high-pressure plunger pumps have been engineered to complement motor triple plunger pumps, providing a comprehensive and powerful solution. Whether you need to tackle challenging industrial tasks or operate heavy machinery, our pumps will meet and exceed your expectations.
