MEYLE and MEYLE-HD water pumps: Raising the benchmark with SiC/SiC mechanical seals

Additional 100,000-miles minimum performance guarantee to complement applicable guarantee period

Featuring silicon carbide mechanical seals, MEYLE and MEYLE-HD water pumps outperform conventional designs in terms of quality: 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.
