How CPE Rotary Vacuum Pan Filters Work
The pan is divided into wedge shaped segments and rotates at a speed from 0.1 to 2.0 rpm.
All segments are covered with filter media appropriate to the slurry and evacuated through an automatic valve which separates the mother liquor from the wash liquor when wash operations are required.
The feed slurry enters the top mounted feed box which distributes the slurry evenly across the pan and the mother liquor is quickly removed under the combined forces of vacuum and gravity.

CPE Pan Filter Features
|Centre Hub with 3-Piece Design||Offering pan deck flatness of +/- 1.0 mm|
|Feed Trough||Rather than a single or dual filling point|
|Washing Weirs||Flooded design to ensure even wash throughout the circumference of the pan|
|Valve Design||Enhanced wear performance, simple changeover maintenance, minimised friction loses caused by the sharp transition from the pan deck to the valve system|
|Drainage Inserts||Accelerates drainage rates|
When is Rotary Vacuum Pan Filter Used
Rotary pan filters are usually used for continuous dewatering of slurries with coarse aggregates and medium to high solids contents. Cake is the filtration product. Pan filters are suitable for the applications where multiple cake wash is required.
Why Use CPE Pan Filters
- High throughput per square meter of filtering area
- Filtration and wash stages visible for ease of control
- Multiple wash stages including counter current washing
- Superior pan flatness for minimum cake heel
- Decade of design and manufacture experience
- Retrofit and modification services
For decades, CPE has pioneered the design modification of horizontal pan filters. Our pan filter design today has evolved to be the best in its class with below key features:
Filtration Process Optimisation
We offer retrofit and upgrade services for pan filters aiming to enhance the filtration performance and capacity, increase operation safety, and reduce recurring maintenance shutdowns.
