KCB cast iron gear pump is an external gear pump featuring a compact structure, low noise, long service life, and simple maintenance. It is primarily used for handling non-corrosive lubricants with temperatures below 300°C and viscosities ranging from 5 to 1500 cst, including crude oil, diesel, heavy oil, vegetable oil, and lubricating oil. This equipment employs advanced gear design and precision manufacturing techniques to effectively reduce energy consumption during the pumping process, thereby enhancing overall pumping efficiency and extending its service life.
