Ceramic Filter Plates and Vacuum Disk Filter Spare Parts
Identify the existing filter and the part interface before requesting replacement ceramic sectors or disk filter spares. Two sectors with a similar outline can differ at the mounting points, liquid connection or sealing face.
Information to Supply by Part
| Part | Information needed to check fit |
|---|---|
| Ceramic sectors | Filter make and model, part number, sector dimensions, mounting and port details, seal type and media specification if known. |
| Scrapers and wear parts | Material, dimensions, orientation, mounting centres and clearance. Describe the wear pattern. |
| Seals and distribution components | Assembly drawing or part number, connection dimensions, wetted material and service conditions. |
Check the Cause of Repeat Failures
For rapid blinding, breakage or poor release, share when the problem starts and whether it followed a feed or cleaning change. Include slurry chemistry, temperature and cleaning practice where relevant. Comparing a used part with the drawing helps distinguish wear or modification from the original dimensions.
See the vacuum ceramic disk filter for the assembly context. For an older machine with incomplete drawings, include the available dimensions and ask about inspection or retrofit support.
Match the Mechanical Fit and the Filtration Duty
For a ceramic plate or sector, start with the original part drawing if available. Verify the outer profile, thickness, mounting centres, filtrate outlet position and seal seating against an unworn reference. If the only sample is used, mark the worn surfaces so that wear is not copied into the replacement. Confirm the original ceramic specification where known. Mechanical fit alone does not establish filtration rate, filtrate quality or cleaning response.
When the original part number is missing, send the nameplate, a dimensioned sketch and photos of both faces, the outlet and the assembled joint. Show a scale and identify which dimensions are measured on the machine. If drawings and measurements disagree, resolve the discrepancy before ordering a full set. A first article can be checked for mounting, sealing, scraper clearance and operation before a larger order.
When a Replacement Part May Not Fix the Fault
| Symptom | Checks to narrow the cause |
|---|---|
| Rate drops across several discs | Compare feed solids, vacuum and cleaning recovery with the normal baseline. Check whether the change affects all discs or a single group. |
| Cloudy filtrate after maintenance | Check the installed sectors, seals and connections for damage, poor seating or leakage. Separate startup conditions from persistent solids carryover. |
| Repeated breakage at one position | Record the position and crack pattern. Check mounting, scraper clearance and possible contact or interference before repeating the order. |
| Cake sticks after a media change | Compare sector specification, feed changes and scraper condition. Check cake formation and release together on representative feed. |
PORVOO can review a like-for-like replacement or a modified part against the existing assembly. For a change in sector type, agree the trial quantity, fit checks and what counts as acceptable release and filtrate quality. Include any change to cleaning chemistry or seals in the review. The Metso ceramic filter brochure illustrates why ceramic media and regeneration are evaluated together.
Discuss Your Project
Send the machine nameplate, part number or drawing, a photo of the mounting and connection, and the quantity required. State whether the request is a like-for-like replacement or a recurring fault.
