Each Visun water pump features the latest technology, including low friction seals, which are arguably the water pump’s most critical component because the seal must not only prevent coolant leakage, but also provide a long service life. As a result, the highest quality materials have been used in the seal manufacturing process.

Additional design features include coolant-resistant, long service life grease for the bearings and pump specific impellers that are optimized for each individual application and designed to ensure efficient coolant flow throughout the engine and prevent cavitation within the coolant. Impeller design is extremely complex and requires both high-tech software and comprehensive real world testing to ensure the performance of the finished product.

Finally, the main water pump bodies are designed to support external loads from the associated components in the drive belt system, as well as engine vibrations and thermal movement, while remaining perfectly watertight in all conditions.
