ZYB series gear pump is an external gear-type positive displacement pump specifically designed for the transfer of medium- to high-pressure, high-temperature, and contaminated media. It is ideal for conveying low-lubricity, high-viscosity media containing non-metallic particles, such as residual oil, heavy oil, and coal tar. Replacing conventional gear pumps in applications involving media containing impurities, it resolves issues such as pressure instability, reduced service life, and even pump seizure, leading to its increasing adoption in fields such as asphalt road construction, petroleum, petrochemicals, and industrial combustion, where it delivers outstanding performance.
Product Details:
ZYB series gear pumps primarily use gears as their core working elements and are based on the principle of external gear pumps. When the motor drives the drive gear to rotate via a coupling, the sealed volume continuously increases, creating a local vacuum, as the gears continue to rotate, the volume between the teeth gradually decreases, forcing the fluid into the pipeline. The unit also features a rationally designed oil drain and return groove within the pump, which minimizes the torque forces on the gears during operation, reduces bearing loads, significantly decreases wear, and ensures the overall efficiency and stability of the pump.

Application:
ZYB series gear pumps are normally employed to handle liquid media containing non-metallic impurities such as kerosene, heavy oil, residual oil, and fuel oil, provided their temperature does not exceed 260°C and their viscosity does not exceed 150 mm²/s. These pumps are designed to meet the pumping requirements of industries including grain and oil processing, power generation, building materials, daily chemicals, asphalt mixing plants, chemical processing, and road construction.
Feature:
1. This series of pumps features an adjustable gear end-face clearance design that allows periodic adjustment of the operating clearance, ensuring the pump maintains high volumetric efficiency and pressure output even after prolonged operation.
2. Thanks to hydraulic balancing technology, the pumps can maintain long-term continuous operation even under severe conditions such as high-pressure injection of contaminated fuel.
3. The selection of seals can be tailored to specific operating conditions to ensure the equipment remains in optimal working condition at all times.
