Whether in the chemical industry or the petroleum sector, the transportation of heavy oil requires pumping equipment capable of delivering a stable flow rate and reliable operation under harsh working conditions. Yet, renowned for their exceptional ability to handle high-viscosity liquids, KCB gear pumps are broadly employed in heavy oil transportation to effectively increase delivery and production efficiency while reducing equipment maintenance and downtime, ultimately providing reliable and stable fluid solutions for the industrial sector.
In the process of pumping high-viscosity media such as heavy oil, lubricating oil, fuel oil, and asphalt, significant resistance is encountered. The selection of a pump with an inappropriate viscosity rating can lead to unstable flow, insufficient suction, and excessive energy consumption. Nevertheless, the operating principle of this series of gear pumps is based on the rotation of two sets of meshing gears within the pump chamber to facilitate fluid transfer. As the gears rotate, the fluid is drawn into the pump chamber, trapped between the gear teeth and the pump body, and smoothly delivered to the discharge side. This operating mechanism guarantees stable flow delivery even under fluctuating pressure conditions, making it particularly well-suited for industrial oil transfer processes.
KCB high-temperature gear pumps are able to maintain effective volumetric efficiency even as fluid viscosity increases, owing to their gears. The gears are manufactured from high-quality alloy steel through heat treatment processes involving carburizing and quenching, resulting in extremely high hardness and wear resistance. This manufacturing process ensures that the pump maintains precise clearance even during long-term continuous operation under high torque loads, helping extend the equipment’s service life to a certain extent. In addition, the pump is equipped with a well-designed drain groove and return oil structure, which not only effectively balances the radial forces generated during gear rotation but also further reduces mechanical wear, safeguarding long-term operational stability.
Under actual operating conditions, this pump can manage lubricating oil or lubricating oil-like fluids with viscosities as high as 1,500 cSt. It also covers an extremely wide range of parameters, with flow rates ranging from 1.1 m³/h to 800 m³/h, capable of meeting various needs from small lubrication points to large oil depot transfer stations. In addition, to accommodate the various operating environments involved in pumping heavy oil, KCB options can be selected using high-temperature-resistant materials to handle special media such as heavy oil or asphalt at temperatures as high as 300°C, demonstrating the equipment’s excellent adaptability to different media.
To fully account for the actual risks involved in transporting heavy oil, the KCB gear oil pump is fitted with a safety valve that automatically opens in the event of a blockage in the discharge line or an abnormal increase in pressure, effectively protecting the motor and pump housing from overload shocks, a feature that effectively addresses changes in viscosity caused by temperature fluctuations in heavy oil. The equipment features a simple structure and rational design, allowing for fine-tuning to compensate for gear end-face clearance during long-term operation, enabling rapid pressure recovery and significantly reducing maintenance and downtime costs. KCB heavy fuel oil pumps provide efficient and reliable fluid solutions for industries that require the continuous delivery of high-viscosity media. Whether in harsh industrial environments or in fuel systems that demand continuous, high-performance operation, these pumps ensure safe and efficient performance for your heavy fuel oil transfer tasks thanks to their well-engineered operating mechanism, advanced gear design, broad compatibility with various media, and safety features.
