The KCB series gear pump is specifically designed for use in lubrication systems of various mechanical equipment. It is suitable for pumping oils with lubricating properties, provided that their viscosity does not exceed 300cst and the operating temperature remains below 300°C. Additionally, stainless steel versions of the gear pump are ideal for handling edible oils, beverages, and other food-grade liquids.
Each pump is equipped with a shaft seal, which can be either a skeleton oil seal, mechanical seal, or packing seal. The type of seal should be specified when placing an order to ensure it meets your specific requirements.
The pumps are constructed with a cast iron casing and gears made from 45# steel, ensuring durability and efficiency. They are branded under "HG" and are packaged in wooden cases for safe transportation. These pumps originate from China and are classified under HS Code 84131100.
