Blinded cloths restrict filtrate flow, causing longer cycle times and wetter filter cake. This typically occurs when fine solids become embedded in the cloth fibers and cannot be removed through normal washing. If cleaning does not restore performance, replacement is recommended.

Increasing cycle times are usually caused by clogged filter cloths, improper feed pressure, or partially blocked center feed pipes. Over time, these issues reduce flow and slow down filtration efficiency.
Wet filter cake is often caused by low pump pressure, worn cloths, or backflow due to poor discharge piping design. Ensuring proper pressure and replacing cloths can significantly improve cake dryness.
Leaks can occur due to worn gasketing, cracked plates, or insufficient hydraulic pressure. Even a small drop in pressure can prevent proper sealing between plates.

👉 JWI Filter Press Hydraulics
Most JWI filter presses operate between 3,000 and 5,000 PSI depending on the model. If pressure drops below required levels, leaks and poor filtration performance will occur.
Yes, most JWI filter presses can be retrofitted with new cloths, plates, hydraulic systems, and feed pipes. Upgrading components can extend the life of the press and improve performance.
Gasketing ensures a tight seal between plates to prevent leaks during high-pressure operation. Worn or damaged gasketing is one of the most common causes of leaks.
Cracked plates, warped surfaces, or persistent leaks even with good gasketing indicate plate damage. Damaged plates should be replaced to maintain proper sealing and performance.
The center feed pipe delivers slurry evenly into each chamber. If damaged, it can lead to uneven filling, reduced efficiency, and longer cycle times.
This is usually caused by a failing hydraulic cylinder or low system pressure. Without proper closing force, the plates cannot seal correctly.
Lifespan varies by application, but cloths may last months to a year, while plates and structural components can last many years with proper maintenance.
If the cylinder can no longer hold pressure or shows external leakage, rebuilding or replacing is recommended. This is critical for maintaining press performance.
