KCB series gear pump adopts an involute external gear structure, which generates volumetric changes through the meshing and disengagement of the driven gear, thereby achieving the purpose of continuous oil suction and discharge. With its high efficiency, low noise, and long service life, this pump is widely used in industries such as chemicals, petroleum, food, pharmaceuticals, shipping, power, and rubber. 

DG series boiler feed water pump plays an indispensable role in the boiler system, responsible for smoothly and efficiently transporting circulating water to the boiler and return water pipes to maintain heat exchange and energy transfer. However, there may be cases where no water is discharged after startup during use, which may cause the boiler system to malfunction and affect the production process.

ZX series self-priming centrifugal pumps can start normal pumping operations without external priming when sufficient priming water is stored in the pump body. This design allows the pump to perform well in harsh environments where the working site is inconvenient or the concentration of suspended particles in the medium is high, and also simplifies its piping system.

CBN series horizontal gear pumps not only make the hydraulic system run smoothly, but also give the whole production process a reliable and durable power source. With their awesome performance, efficient pumping, and stable operation, they're a key part of industrial hydraulics.

A vacuum pump is a piece of equipment used to create low-pressure or vacuum environments, commonly employed in laboratories, industrial production, and scientific research as a critical component. However, during operation, the exhaust port of a vacuum pump may experience oil leakage, which can impair its performance and lifespan. Therefore, we will provide a detailed explanation of how to address this issue in the following sections.

YHCB series gear pumps belong to a new generation of low-noise, high-efficiency circular-arc gear pumps, designed for conveying mediums such as gasoline, kerosene, diesel oil and mechanical lubricating oil with viscosity of 5-1500 cst and temperature below 80°C. The pumps are designed to be used for the transportation of gasoline, kerosene, diesel oil and mechanical lubricating oil with high viscosity and low temperature.
