McLanahan’s growing might in mining: QUICKCHANGE filter press gains for plant engineers
Reviewed by Tom Sullivan

First reported on International Mining – News
30 Second Briefing
McLanahan Corporation and its Italian sister company Diefenbach have launched the patent-pending QUICKCHANGE™ system for filter presses, introduced in March 2025 and engineered to cut maintenance time through faster, simpler and safer plate change-outs. The system targets high-throughput mining dewatering circuits where conventional filter press maintenance can cause extended downtime and manual handling risk. For plant engineers, QUICKCHANGE™ signals further mechanisation of filter press servicing, with potential to tighten maintenance windows and improve availability without major changes to existing dewatering layouts.
Technical Brief
- QUICKCHANGE™ is a patent-pending mechanical system integrated directly into Diefenbach/McLanahan filter press frames.
- The system is designed to be retrofittable to existing Diefenbach presses without major structural modification.
- Plate handling is mechanised to reduce manual lifting and pinch-point exposure during change-out operations.
- McLanahan cites reduced need for scaffolds or temporary platforms around the press during maintenance.
- The design targets large mining presses where plate packs can exceed several tonnes in aggregate mass.
- QUICKCHANGE™ was jointly engineered between McLanahan’s Hollidaysburg, PA facility and Diefenbach’s Medolago, Italy plant.
- Integration with OEM control systems allows interlocks to prevent motion while operators are in the hazard zone.
- For high-throughput mines, such mechanised change-out systems support tighter lock-out/tag-out windows and clearer task demarcation.
Our Take
In our coverage of mining equipment, post-acquisition product launches on a roughly two-year cadence, as seen here between the 2023 deal and the March 2025 introduction, usually signal that integration of engineering teams and IP has progressed beyond simple branding to genuine platform redesign.
