One of the key features of our high-pressure pump is its forced lubrication and cooling system. This innovative system ensures that the power end of the pump operates smoothly and reliably for a long period of time. With this pump, you can expect stable performance, even under the most demanding conditions.

The power end of our pump is built to last. The crankshaft box is cast with ductile iron, providing exceptional strength and durability. Additionally, the cross head slide is made using cold-set alloy sleeve technology, which offers wear-resistance and low noise operation. With its high precision design, you can depend on this pump to deliver accurate and consistent results.

We have paid attention to every detail in designing this pump. The gear shaft and gear ring surfaces are finely ground, resulting in low running noise. To further enhance the performance and reliability of our pump, we have chosen to use NSK bearings. By utilizing these high-quality bearings, we can ensure that the pump operates smoothly and without any issues.

In addition to its superior performance, our high-pressure pump is also compact in size. This makes it easy to install and integrate into your existing liquid processing system. Its horizontal triple plunger design also contributes to its compactness, while still delivering a high level of power.

With a maximum pressure of 2800 bar, our high-pressure pump is capable of handling even the toughest liquid processing tasks. Whether you need to pump chemicals, oils, or any other liquids, this pump will get the job done efficiently and effectively.
