Diaphragm Filter Plates
Diaphragm filter plates represent a cutting-edge technology in the filter press industry, offering superior performance in solid-liquid separation processes. These specialized components enhance filtration efficiency while reducing processing time and operational costs across multiple industries.
Diaphragm filter plates consist of a base plate and a flexible membrane. When external media (water or compressed air) enters the chamber between the plate and membrane, the membrane inflates to compress the filter cake formed in the chamber between diaphragm plates and chamber plates. This compression significantly improves solid-liquid separation efficiency and increases the solid content percentage of the filter cake.
Key Features
✅ High Tensile Strength & Elongation:
Constructed with precision, our diaphragm filter plates boast high tensile strength and exceptional elongation, ensuring reliable performance under demanding operational conditions.
✅ High Temperature & Corrosion Resistance:
Designed to withstand extreme temperatures and corrosive environments, these filter plates maintain their integrity and functionality, even in harsh industrial settings.
✅ Innovative Design:
The diaphragm filter plate comprises a template and a matching plate. This assembly guarantees optimal performance, creating a tightly sealed chamber when integrated with a casing filter plate. The design effectively enhances the mechanical compression of the filter cake, leading to improved dewatering and filtration efficiency.

Benefits of Using Diaphragm Filter Plates
Shorter Filtration Time
As filtration progresses, cake growth typically slows, requiring longer processing times to achieve low residual moisture content. Diaphragm filter plates significantly reduce filtration time through mechanical compression via the elastic membrane, achieving desired moisture levels faster than conventional systems.
Reduced Washing Time
Conventional filtration components often cause uneven cake formation due to wrinkling or cracking, resulting in inconsistent washing. Diaphragm filter plates prevent this unevenness through gentle membrane pressure during the washing process. The uniform capillary structure formed in the filter cake ensures excellent washing effectiveness while substantially reducing washing liquid consumption.
Lower Residual Moisture Content
The high-pressure filtration process is replaced by compression from the highly elastic membrane against the filter cake. This compression occurs perpendicular to the filtration surface rather than along it. The result is significantly reduced residual moisture content and increased filtrate discharge in a shorter timeframe.
Key Parameters
While exact specifications can vary based on application and design, our diaphragm filter plates generally offer the following parameters:
- Tensile Strength: High-performance rating for industrial demands.
- Elongation: Superior elasticity ensuring minimal damage under pressure.
- Temperature Resistance: Capable of operating in high-temperature environments.
- Corrosion Resistance: Suitable for use in corrosive conditions, extending product lifespan.
- Material Options: Available in both rubber and polypropylene, catering to specific operational needs.
Common Questions
Have More Questions? Our technical team is ready to provide detailed, personalized guidance.
Q1: How do diaphragm filter plates compare to traditional filter plates?
Diaphragm filter plates provide superior performance through additional mechanical compression, resulting in drier filter cakes, faster cycle times, and reduced washing liquid consumption compared to traditional plates.
Q2: What industries benefit most from diaphragm filter plates?
Industries processing slurries with high moisture content or valuable solids particularly benefit from these plates, including mining, chemical processing, pharmaceutical manufacturing, and wastewater treatment.
Q3: How long do diaphragm filter plates typically last?
With proper maintenance, rubber diaphragm plates typically last 1-3 years, while polypropylene versions may last 3-5 years depending on operating conditions and the nature of processed materials.
Q4: Can membranes be replaced or must the entire plate be replaced?
Rubber diaphragm plates feature replaceable membranes, while polypropylene versions typically require complete plate replacement when the membrane fails.
Q5: What pressures can diaphragm filter plates withstand?
Our diaphragm filter plates are engineered to withstand operating pressures between 6-16 bar, depending on the specific model and application requirements.
Q6: Are these plates compatible with existing filter press systems?
Most diaphragm filter plates can be integrated into existing filter press systems with minimal modifications, though compatibility should be verified based on specific dimensions and connection types.
