SiC/SiC Seals Step Up Quality of MEYLE and MEYLE-HD Water Pumps

One of the leading causes of engine damage is a defective water pump. In several cases, the problem starts with a leaking mechanical seal, which is why material quality is an important factor.

The use of SiC/SiC mechanical seals enables MEYLE and MEYLE-HD water pumps to surpass the quality standards usually available on the independent market. As a result, a number of automakers rely on this type of sealing that is now fitted in the majority of MEYLE water pump designs. It boasts an extremely narrow sealing gap combined with a high-grade silicon carbide material, which guards the water pump against wear and contamination. In fact, even the smallest particles are ground down in an instant, and run-in period is not required as the water pump is securely water-tight after installation.

As compared to the traditional hard carbon material normally used in aftermarket applications, silicon carbide sliding face material pairings offer superior thermal conductivity, thus preventing the risk of crack formation due to thermal stress. This helps prolong the water pump life.

All the MEYLE water pumps designed by Wulf Gaertner Autoparts are offered with a (160,934 kilometers minimum performance guarantee apart from the respective guarantee period. This guarantee is offered independently of the standard four-year guarantee provided for all MEYLE-HD part, and covers part mileage.
