Maintenance

Scheduled attention is needed by high-pressure pumps, seals, door seals, hoses, vapor condenser, nozzles and pipes. The intervals are not standardized — a system in three-shift operation with aggressive contamination needs a different rhythm than one in single-shift operation. If intervals are not kept, nozzles and pipes get dirty or clogged.

A neglected routine turns into a process problem: the system runs, but the cleaning no longer lands where it should. The critical point is that this wear does not come suddenly — it announces itself, if someone looks.

Yes. Systems that do not come from us are maintained and repaired as well. Before the first intervention on a third-party system comes an on-site survey — with incomplete documents it is not optional, but a prerequisite. Only then can it be said which subassemblies need attention in which rhythm.

We aim for 24 hours. Via our regional service partners, the response time is 24 to 48 hours depending on region and type of malfunction — that describes the normal case, not a blanket assurance for every system. A service contract is at the same time the prerequisite for the 24/7 emergency service; scope and the response time binding in the individual case are agreed in it.

Almost never the pressure alone, and that is why the search most often ends there too early. What leaves the pressure on the gauge unchanged and still reduces the effect on the component: worn nozzles — the bore widens, volume flow and spray pattern change with it. Clogged nozzles that no longer reach individual areas at all. A dirty filter that throttles the volume flow in the circuit. A changed media quality — dirt load, water quality or concentration. And the position of the component: if it is held or positioned differently, spray shadow forms in places that were hit before. Just as often it is not the system that has changed, but the task: a new batch of material, a different machining step before, more firmly adhering or baked-on contamination. Then the system works unchanged — only against a different contamination than the one it was designed for. The sensible sequence is therefore: pressure, volume flow, filter condition, nozzles and spray pattern, media quality, component fixture — and last, the question of whether the contamination is still the same.
