ALLWEILER NTT 32-160 U5 AW4 Pump Repair
ALLWEILER pumps are above all reliability and quality!
But no matter how correct the mechanism is, there are parts that need to be replaced or restored over time. Usually, rolling bearings, cuffs, and mechanical seals are replaced. Replacement of bearings is mandatory when a certain service life of the watch is running, regardless of their condition. The manufacturer describes the routine maintenance for service and warranty service. If the pumps operate in high temperature conditions, like hot oil pumps and with increased loads, then the service life of the bearings is reduced, so as not to cause their mechanical seal failure and workings on the pump shaft and housing.
