We had a Graco ST Max II 595 in our shop for repair.

Several components of the pump were worn. Therefore, the question arose whether individual parts of the pump should be replaced or the complete pump should be replaced.

The new part of the video series Airless Tips is about the repair of the pump of the Graco Classic and ST Max models.

Replace piston & components or complete pump?

In this way, it is possible to determine directly which spare parts are required for the maintenance and repair of the airless unit.

Then it can be quickly calculated whether the repair of the lower pump is worthwhile or whether the pump should be replaced completely.
