Water pumps are designed to provide a constant circulation of coolant in engine cooling system. HOLA water pump construction includes five main elements: pump body or cover, assembled shaft and bearing with impeller, timing pulley (pulley hub) and labyrinth seal installed. Pump parts have special protective corrosion resistant coating. Specially designed impeller allows optimal flow and pressure created by water pump. Application of enhanced high-quality bearing provides extended operating life of product.
Advantages of aluminum HOLA radiators include higher heat exchange, improved mechanical strength, wide stock of excessive pressure and long-living. Effective heat exchange is ensured by using ribbing belts and fins in special designed direction. Quantity of fins and space between them are designed for maximum heat exchange under different speed of air flow.
