KCB series gear pumps deliver exceptional performance in fuel supply systems due to their design structure, operating principle, and specialized manufacturing techniques, which ensure high efficiency and smooth, low-pulsation flow.
It is a positive displacement gear pump that relies on the changing enclosed volume formed by gear meshing to convey media. This structural feature enables the formation of effective oil film lubrication between the internal gears and bushings when conveying lubricating oil media, significantly reducing wear rates while achieving high operational efficiency and extended service life. Thanks to the transmission characteristics of its involute gear meshing, it delivers low-pulsation continuous oil supply to maintain uninterrupted combustion, with outlet pressure fluctuations kept within ±5% to effectively meet the stringent requirements for stable flow in fuel supply, making it a crucial component for stable boiler operation.
KCB gear oil transfer pump employs a tooth profile optimized for lubricating media and metallurgical sleeve materials to achieve excellent self-lubricating friction performance. Therefore, when conveying media such as heavy oil containing trace solid particles, heavy oil, and vegetable oil, the internal wear rate is significantly lower than that of conventional pumps, extending maintenance intervals by 25%-50% compared to other pump types. It can also be equipped with a thermal insulation jacket design, which maintains the flow temperature of fuel oil within the pump chamber through continuous heating by steam or thermal oil. This effectively solves the problem of high-pour-point fuel oil solidifying inside the pump and fundamentally prevents equipment jamming or damage caused by medium solidification within the pump chamber.
This pump features a simple structure, rational design, and high standardization, meaning its procurement cost in fuel systems is approximately 18-35% lower than that of specialized pumps under equivalent operating conditions, thereby reducing production costs. The replaceable bushings and floating sleeve with automatic clearance compensation design eliminate the need to replace the entire pump body during wear maintenance, requiring only replacement of wear parts to restore performance, thereby reducing repair costs and minimizing downtime to lessen production disruptions. Simultaneously, its compact and robust construction allows for relatively flexible installation environments while offering enhanced resistance to impact and pipeline stress, ensuring long-term stable operation of the fuel supply system under various conditions. By incorporating a well-designed return line and pressure protection devices, the system automatically adjusts output to prevent overload risks.
In fuel supply systems, the KCB horizontal gear pump maintains high delivery efficiency through its rational internal structure, stable long-term performance, reliable wear resistance, and low maintenance costs, making it a durable core equipment choice for traditional fuel supply systems.
