Verschleissbeständige Kraftstoffpumpe

摘要

A wear resistant fuel pump (12) for a vehicle includes a pump section (14) having a flow channel (43) and a rotatable impeller (28) cooperating with said flow channel (43) to pump fuel therethrough. The fuel pump (12) also includes a motor section (16) disposed adjacent the pump section (14) and having a motor (30) to rotate the impeller (28). The fuel pump (12) further includes an outlet section (18) disposed adjacent the motor section (16) to allow pumped fuel to exit the fuel pump (12). The pump section (14) includes a plurality of plates (34,36) disposed axially adjacent to and cooperating with the impeller (28). At least one of the plates (34,36) includes a wear insert (56) that improves abrasion wear characteristics therebetween.
