Advanced TPE Diaphragm Technology: Utilizes a durable Thermoplastic Elastomer (TPE) diaphragm, offering exceptional longevity, reliable stability, and broad compatibility with various chemicals, making it suitable for multiple R&D applications.
High-Pressure Water Squeeze: Employs hydraulic pressure technology capable of reaching 2.0 MPa and above, ensuring superior cake dryness compared to standard filtration.
Variable Chamber Design: This technology adapts to different process requirements in chemical, pharmaceutical, and mineral testing, significantly enhancing filtration efficiency and reducing residual moisture content.
Efficient High-Pressure Dewatering: Effectively reduces filter cake moisture to meet disposal standards such as landfill or incineration. Achieves up to 50% reduction in cake weight and volume compared to traditional dewatering equipment, minimizing waste handling costs.
Complete Automation & Unmanned Operation: The entire system is designed for fully automatic operation. Integrated with an online cloth washing system and electronic valves/instrumentation, it enables continuous, unattended operation, maximizing lab productivity and safety.
The operation follows a precise, automated sequence to ensure maximum efficiency and dryness:
1、Close & Press Plates – Hydraulic system seals the filter chambers.
2、Feed & Filter – Slurry is pumped in; solids form cake, liquid drains out.
3、Diaphragm Squeeze – High-pressure water/air expands diaphragms to compress cake (core dewatering step).
4、 Air Blow (Optional) – Compressed air removes additional moisture for ultra-dry cake.
5、Release Pressure – System pressure is safely released.
6、Open Plates – Plate pack separates for discharge.
7、Auto Discharge – Filter cakes fall cleanly by gravity.
8、Cloth Wash (Optional) – Automatic cleaning maintains filter performance.
