ZYB series gear pumps are routinely employed to convey heavy oil, kerosene, fuel oil, and other high-viscosity liquid media within operating environments characterized by high temperatures, high viscosity, and continuous operation under complex conditions. In such demanding conditions, pumping equipment must possess sufficient mechanical strength while maintaining continuous and stable flow output to ensure the safe operation of the entire production process and optimal pumping efficiency. With its rational structural design and sound operating principles, this product is capable of delivering stable flow even under complex operating conditions, effectively achieving high-efficiency operation.
Through the continuous meshing of the drive gear and the driven gear, this product series creates a continuously expanding sealed space on the suction side, drawing the fluid into the pump chamber while simultaneously forcing it out as it is transported to the discharge side, at which point the gears re-mesh. Different from traditional centrifugal pumps, which rely on the conversion of fluid kinetic energy, the entire delivery process of this product is accomplished through the periodic changes in the sealed volume, ensuring stable delivery efficiency even when handling fluids with significant viscosity fluctuations. ZYB horizontal gear pumps feature an optimized tooth profile and durable materials, effectively addressing issues such as reduced flow rate and delivery interruptions caused by increased resistance in conventional pumping equipment, while also minimizing shear loss during fluid transfer. With its well-designed flow path, the pump reduces fluid stagnation within the chamber, ensuring a smoother and more stable transfer of high-viscosity fluids and thereby minimizing the impact of flow rate fluctuations on the fluid.
Temperature fluctuations are also a key factor affecting pumping stability when conveying heavy oil or residual oil, as a drop in temperature often leads to a rapid increase in viscosity, which in turn increases pumping resistance. To address this issue, this product can be equipped with a heat-insulating jacket that allows steam, heat transfer oil, or other heating media to be circulated according to process requirements, providing continuous thermal insulation for both the pump body and the conveyed medium. The stable pumping temperature helps maintain the medium’s viscosity within an optimal range, minimizing flow fluctuations caused by viscosity changes and ensuring a consistent flow rate even during prolonged operation.
The core components of the ZYB oil pump, including gears and bushings, are manufactured from wear-resistant, high-performance materials, combined with precision machining and heat treatment processes to enhance the surface hardness of the gears, effectively extending the equipment’s service life. It also minimizes leakage of the medium from the high-pressure side to the low-pressure side and improves volumetric efficiency through optimal control of gear end face clearance and radial sealing structures. In addition, the unit is equipped with a robust transmission structure capable of efficiently transferring power from the drive unit to the gear system, ensuring relatively stable rotational speed even under conditions of high fluid viscosity and heavy startup loads, and reducing uneven delivery caused by power fluctuations. ZYB high viscosity gear pumps rely on the positive displacement principle, an optimized gear design, an insulated jacket, and durable core components to effectively handle high-viscosity, low-temperature, and poor-flow conditions, as well as continuous operation, providing efficient flow delivery for continuous and stable production.
