Your pressure leaf filter is still in operation – But the manufacturer no longer exists?

  • Spare Parts & Exchange

Many industrial filtration systems have been in continuous service for decades. This is especially true for pressure leaf filters from Schenk, SeitzSchenk and Chemap which earned their good reputation through robust engineering, strong performance, and simple day-to-day operation.

But excellent equipment alone doesn’t guarantee long-term reliability. Filters age. Components wear down. Bearings, gaskets, filter cloths, filter leaves, and hydraulic parts reach the end of their lifecycle. And sooner or later many operators face the question:

When the manufacturer no longer exists – who provides support for your filter?

Pressure leaf filters like the ZHF series from Schenk and SeitzSchenk were produced by companies whose ownership structures changed repeatedly over time. The original manufacturers disappeared, brands were merged, and documentation was archived deep within global corporate groups.

As an operator of such a filter, the consequences are clear:

  • Spare parts become hard to source
  • Manufacturer’s documentation might not be available
  • Service personnel familiar with the systems has become rare
  • The risk of incorrect parts or unplanned downtime increases

These are challenges no production plant can afford.

What you really need as an operator

  • A reliable partner – Someone who knows the equipment, its history, and its technical variations.
  • Easy to reach – A partner who answers quickly — without long waiting times or complex corporate procedures.
  • Technically experienced – Someone who understands the needs of your filtration process, understands the original system design, and knows which spare parts truly fit.
  • Solutions-focused – A provider who can give clear recommendations, support troubleshooting, and guide you through modernization steps.
  • Guaranteed compatibility – Suppliers who can deliver spare parts, filter elements, seals, cloths, and components that match your system — in quality, performance, and longevity.
