1. Product DescriptionThe KCB/2CY series of gear oil pumps are known for their compact and simple design, ease of operation, and low maintenance requirements. These pumps are ideal for transporting various types of oils such as petroleum, diesel, and lubricants. When equipped with copper gears, they can handle fluids with low flash points, such as gasoline and benzene, at temperatures below 70°C.
They are widely used in oil reservoirs, piers, ships, mining sites, factories, and farms. The 2CY series is specifically designed for transporting viscous lubricants for mechanical equipment. With stainless steel gears, these pumps can also be used to pump cooking oils or beverages.

6. Product Advantages
1. Driving Gear Passive Gear
The active/passive gears undergo high temperature quenching and ion carburizing. This process increases the hardness, wear resistance, and heat resistance of the gears, significantly extending their service life.
2. High Temperature Bearing
High temperature bearings are capable of handling large torque loads and offer excellent stability under high temperatures. They have high load capacity, good heat resistance, and long service life. For KCB18.3-KCB83.3 models, sliding bearings are used, while rolling bearings are used for models above KCB200.
3. Mechanical Seal
Carbide mechanical seals provide excellent heat and impact resistance, a low friction coefficient, self-lubricating properties, and reliable performance. They are leakage-free, heat-resistant, wear-resistant, and corrosion-resistant.
4. Integral Coupling
DEFU high-temperature gear pumps use integral couplings, which are safe and reliable, have good concentricity, and offer long service life. They can withstand heavy loads and have strong torque capabilities.
5. 100% Copper Motor
DEFU gear pumps are paired with 100% copper motors, ensuring stable operation, low heat generation, standard output power, and extended service life.
6. Certificate of Inspection
Every DEFU gear pump is strictly tested before leaving the factory and comes with a certificate, manual, test data report, and a Chinese Classification Society (CCS) certificate.
