SKF AquaMax - Not an Ordinary Water Pump
The automotive cooling system is one of the most critical operating systems in modern vehicles and SKF keeps pace with the latest vehicle technology developments with the company's AquaMax water pump.
The water pump is the heart of the automotive cooling system, typically a belt-driven centrifugal pump, and failure will cause breakdowns and can also result in extensive damage. Flat tyres and out-of-fuel situations are followed closely by cooling system failure is one of the main causes of breakdowns; the pump circulates coolant throughout the system while the engine is running and drive belt failure causes water pump malfunction.
The SKF logo stamped on to the water pump and the blue impeller, differentiates the SKF AquaMax from other traditional pumps available in the replacement market. The traditional SKF quality goes much deeper than just appearance As, through design and testing, AquaMax boasts many built-in features to offer a pump that matches and even surpasses the performance of OES water pumps.
Impeller design and material selection ensure maximum flow and pressure. A high-tech blue coating, used in the aerospace industry, minimises problems with inferior coolants, preventing small particles of cooling liquid from sticking to the impeller for maximum corrosion resistance.
Unlike inferior or rebuilt aftermarket pumps that can fail prematurely, SKF original water pumps are designed and manufactured to meet and exceed all OE specifications. Precise manufacturing of all components guarantees precise fit, easy installation, and superior performance.
With each new generation of vehicles, automotive designers and manufacturers are seeking greater performance and efficiency, while at the same time attempting to reduce maintenance. With AquaMax, SKF has created a water pump that meets the rigorous requirements of OEMs by using dedicated testing. Premature leaks cause 90 % of all water pump breakdowns and thorough testing ensures that unitised mechanical seals eliminate these premature leaks. SKF AquaMax is subjected to rigorous testing to ensure superior performance and endurance. When run for 1 000 hours at average car speeds of 100 km/h, vapour leakage is well below acceptable OE standards and far below that common with typical aftermarket replacement units.
Through SKF's bearing expertise, only the highest quality spindles are selected to meet optimum capacity loads and long life performance. Attaining optimal flow throughout the cooling system requires a scientific approach and meticulous attention to detail during the design and manufacturing process. AquaMax water pumps benefit from sophisticated hydraulic flow analysis using the latest computer aided design analysis tools.
