1. Product DescriptionThe KCB/2CY series gear oil pumps are known for their compact and simple design, making them easy to operate and maintain. 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 like 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 mainly designed for transporting viscous lubricants for mechanical equipment. With stainless steel gears, the pumps can also be used for pumping cooking oils or beverages.

6. Product Advantages
1. Driving Gear Passive Gear
The active/passive gear undergoes high-temperature quenching and ion carburizing treatment. This enhances the hardness, wear resistance, and heat resistance of the gears, significantly extending their service life.
2. High-Temperature Bearing
These bearings are designed to withstand heavy loads and high temperatures, ensuring stable operation and long service life. DEFU’s KCB18.3-KCB83.3 models use sliding bearings, while models above KCB200 use rolling bearings.
3. Mechanical Seal
Equipped with a carbide mechanical seal, these pumps offer excellent heat and impact resistance, low friction coefficient, self-lubrication properties, and high reliability. They ensure no leakage, high temperature resistance, wear resistance, and corrosion resistance.
4. Integral Coupling
DEFU high-temperature gear pumps use an integral coupling, which ensures safe and reliable operation, good concentricity, and a long service life. It can withstand high torque under heavy load conditions.
5. 100% Copper Motor
DEFU pumps are paired with 100% copper motors, providing stable operation, low heat generation, standard output power, and a long service life.
6. Certificate of Inspection
Each pump from DEFU is strictly tested before leaving the factory, comes with a certificate, manual, test report, and is shipped with a Chinese Classification Society (CCS) certificate.
