Our water pum application
KOALADIESEL engine water pump extensively applied in various diesel engines, offering power solutions for multiple industries. Whether in the automotive sector, shipping, energy industry, construction, agriculture, and other fields, they serve as crucial components ensuring efficient engine operation and stable performance.
The structure of water pump
The engine water pump has several key components that work together seamlessly to achieve its vital functions.
The impeller, housed within the pump’s casing, draws coolant from the engine and propels it through the cooling system.
This impeller operates in a rotational motion, generating the necessary pressure for efficient coolant circulation.
The shaft connects the impeller to the engine’s drive belt, transmitting the rotational energy required to power the water pump.
Seals and gaskets are critical in maintaining a secure enclosure for the pump’s components, preventing coolant leakage,
and ensuring the pump’s efficiency.

The water pump process flow
Engine water pumps are integral components of various mechanical systems, ensuring optimal cooling and
circulation of coolant fluids.The intricate process involved in their manufacturing is a testament to the precision
and expertise requiredto create products that meet the highest quality standards.
STEP 1
water pump shell mechanical modeling
This step is critical as it forms the foundation for the entire manufacturing process. The model serves as a blueprint for subsequent stages and influences the pump’s final dimensions and design.
STEP 2
cast&smelting
Once the shell’s model is finalized, the next step is casting. Molten metal, often aluminum or alloy, is carefully poured into the mold to shape the shell. This stage determines the pump’s overall structure and strength, ensuring it can withstand the demands of its intended application.
STEP 3
water pump shell Shot Blasting
To achieve a pristine surface finish, the cast shell undergoes shot blasting. This process involves propelling abrasive materials at high speeds onto the shell’s surface, effectively removing any impurities and roughness. The result is a smooth and clean exterior ready for further refinement.
STEP 4
water pump shell polishing
Shell polishing takes the refinement process a step further. The cast shell undergoes polishing to eliminate any remaining imperfections and achieve a high level of precision. This stage ensures that the shell’s dimensions align with the intended specifications.
STEP 5
Impeller Machining
The impeller, a critical component responsible for fluid circulation, is meticulously machined in this stage. Its design and dimensions play a significant role in the pump’s efficiency. Precision machining ensures optimal fluid flow and minimizes energy wastage.
STEP 6
Gear Tooth Grinding
Since grinding corrects all errors in gear pre-machining, the machining accuracy is higher, contributing to the service life and stable performance of the pump.
STEP 7
Water pump assembly
various components including the casing, shaft connecting shafts, impellers, and gears are carefully assembled.
STEP 8
Inspection
Before the finished product is shipped, it needs to be under strict inspection. From size to functionality, every aspect needs to be carefully evaluated to meet strict quality standards.
