Core component driving coolant circulation.

Constructed from high-strength aluminum alloy for lightweight durability, corrosion resistance, and dynamic balance at high speeds. Resists erosion from coolant impurities, extending service life.

Sealing Components:

Includes gaskets and seals to prevent coolant leakage.

Gaskets use oil- and high-temperature-resistant rubber for reliable sealing under extreme conditions.

Seals made of fluororubber, offering superior chemical resistance, high-temperature tolerance, and anti-aging properties.

Bearings:

Supports impeller rotation.

Manufactured from heat-treated alloy steel for high hardness, wear resistance, and load capacity. Ensures stable operation with minimal vibration and noise.

Sleeve:

Protects the pump shaft from wear and corrosion.

Bronze construction provides excellent anti-friction properties, wear resistance, and durability. Maintains smooth shaft operation.

Installation Steps:

Drain the cooling system completely to prevent leakage.

Remove the original water pump and disassemble components (impeller, seals, bearings, sleeve).

Clean and inspect the pump housing for damage or debris.

Install new components in sequence per instructions. Apply sealant to gaskets for optimal sealing.

Test the pump for smooth impeller rotation.

Refill coolant, start the engine, and check for leaks or irregularities.

Precautions:

Wear protective gear (gloves, goggles) during repairs.

Follow instructions strictly; avoid using incorrect tools or altering installation steps.

Inspect components for defects before installation.

Perform a full system check post-repair, ensuring proper coolant levels and secure connections.

Stop operation immediately if issues arise to prevent further damage.
