ZYB series high pressure gear pumps are capable of handling diesel fuel, heavy oil, residual oil, coal tar, and other low-grade, poor-quality combustion oils containing non-metallic impurities at medium temperatures not exceeding 260°C. As such, they are particularly suitable for fuel injection applications in industries such as chemicals, petroleum, construction materials, daily chemicals, grain and oil, power generation, and asphalt mixing plants. Moreover, this pump employs hydraulic balancing technology, ensuring high efficiency, minimal pulsation, low noise levels, and extended pressure retention time even under high-pressure operating conditions.
