HAMBURG, Germany — A defective water pump can quickly cause major engine damage. In many cases, the root cause is a leaking mechanical seal, which is why material quality is a critical factor.
Using silicon carbide mechanical seals (SiC/SiC mechanical seals), MEYLE and MEYLE-HD water pumps far exceed the quality standards typically available on the independent aftermarket, according to the company. Leading carmakers rely on this type of sealing now fitted in the majority of available MEYLE water pump designs. The extremely narrow sealing gap combined with a high-grade silicon carbide material – a particularly robust compound – helps protect the water pump against wear and contamination. Even the smallest of particles are ground down instantly. No run-in period is required – the water pump is perfectly water-tight immediately after installation.
All water pumps designed by Hamburg manufacturer Wulf Gaertner Autoparts come with a 100,000-miles (160,934 kilometres) minimum performance guarantee – in addition to the respective guarantee period. The performance guarantee is offered independently of the standard four-year guarantee given for all MEYLE-HD parts and exclusively covers part mileage. Further information on the MEYLE guarantee policy is available here
. The additional performance guarantee is the natural result of the many benefits SiC/SiC mechanical seals have to offer.
Compared to conventional hard carbon material typically used in aftermarket applications, silicon carbide sliding face material pairings offer excellent thermal conductivity thereby preventing the risk of crack formation due to thermal stress. The result: a prolonged water pump life.
