One of the standout features of our high pressure pump is its forced lubrication and cooling system. This innovative system guarantees long-term stable operation of the power end, even under the most demanding conditions. It effectively lubricates the key components, reducing friction and wear, while also efficiently dissipating heat, preventing overheating.

Another notable feature is the crankshaft box, which is made from ductile iron. This material provides exceptional strength and durability, ensuring the pump can withstand high pressures and heavy use. Additionally, the cross head slide is made using cold-set alloy sleeve technology, which enhances its wear-resistance, reduces noise, and enables high precision operation.
Coupled with the use of NSK bearings, known for their superior quality and reliability, we guarantee stable operation and minimal maintenance requirements.

Our high pressure plunger pump stands out from the competition due to its exceptional value for money. We have carefully designed and manufactured this pump to offer the highest quality at a competitive price. We understand the importance of providing reliable and efficient pumping solutions without breaking the bank. With our compact vertical design, this pump can be easily integrated into existing systems, saving valuable space without compromising on performance.
