Filter Press Plate

Name: Filter Press Plate | Slurry Separation Support Plate – Frigate
Price: 249.00 USD
Availability: InStock

Filter Press Plate is engineered to resist compressive forces exceeding 25 bar during press closure. The high modulus material matrix and reinforced rib architecture provide excellent stiffness, ensuring no warping or deflection over multiple filtration cycles. Load fatigue is minimized through controlled wall thickness and isotropic structural distribution.

Overall Plate Dimensions

500–2000 mm (L) × 500–2000 mm (W) (±1.5 mm), Custom sizes up to 2500 mm (±2 mm)

Thickness

30–100 mm (±0.5 mm for PP, ±1.0 mm for metal), Chamber Depth – 20–50 mm (±0.3 mm)

Material Specification

Ductile Iron (ASTM A536), 316L SS (ASTM A240), Polypropylene (Machined from billet)

Filtration Chamber Volume

0.5–5 L per chamber (±2%), Depth – 20–50 mm (±0.5 mm)

Port Hole Diameters

Feed/Filtrate – 25–80 mm (±0.5 mm), Wash – 15–50 mm (±0.3 mm)

Product Description

Filter Press Plate is manufactured with surface flatness within ±0.3 mm and edge squareness within ±0.2°, preventing leakage and misalignment in high-pressure packs. These tolerances reduce bypass flow and ensure uniform gasket sealing, critical for repeatable filtration in pharmaceutical and chemical processes.

Number/Location of Ports

2–4 ports (positional tolerance ±0.8 mm), Aligned within 0.5 mm/m across plate stack

Gasket Sealing Surface

Ra ≤3.2 µm (metal), Ra ≤6.3 µm (PP), Groove Depth – 5–10 mm (±0.2 mm)

Drainage Surface Design

Pyramid Pips (5–10 mm height, ±0.3 mm), Grooves (2–5 mm wide, ±0.2 mm spacing)

Operating Pressure Rating

7–15 bar (standard), up to 30 bar (high-pressure designs, ASME BPVC compliant)

Certification Standard

ISO 9001, ASME BPE (for pharma), DIN 28003 (Pressure Filters), FDA CFR 21 (PP for food)

Technical Advantages

Filter Press Plate incorporates engineered drainage surfaces with controlled rib depth and pattern orientation. This promotes even slurry distribution and reduces differential pressure buildup. Consistent cake formation is achieved across the plate area, improving cycle uniformity and press efficiency.

Filter Press Plate is produced using chemically inert polymers capable of operating in pH ranges from 1 to 14. These plates maintain mechanical properties in aggressive media, making them suitable for acid leaching, alkaline digestion, and high-solids slurries found in metallurgical and chemical plants.

Industry Applications

Mineral Processing

Filter Press Plate separates fine tailings from slurry streams, optimizing water recovery and minimizing solids carryover in flotation circuits.

Chemical Manufacturing

Filter Press Plate removes precipitated solids after crystallization, ensuring purity and controlled moisture in batch chemical separation processes.

Pharmaceutical Production

Filter Press Plate is used in API recovery by separating biomass and active compounds under controlled pressure and aseptic conditions.

Food and Beverage Processing

Filter Press Plate filters edible oils, juices, and sweeteners by removing suspended solids without altering thermal or chemical characteristics.

Metal Finishing and Electroplating

Filter Press Plate captures sludge from rinse tanks and drag-out recovery units, maintaining electrolyte purity and preventing downstream contamination.

Wastewater Treatment

Filter Press Plate dewaters industrial sludge, reducing moisture content for safe disposal and improving solids handling efficiency in treatment facilities.

Controlled Filtrate Flow Path

Filter Press Plate integrates symmetrical port design and laminar channel routing to minimize pressure drop and backflow. Port diameter tolerances are tightly controlled to ±0.05 mm, ensuring consistent filtrate evacuation, preventing clogging, and reducing cycle delays caused by non-uniform flow.

Membrane-type Filter Press Plate allows secondary cake compression using elastomeric diaphragms, reducing residual moisture content to below 20% in suitable applications. The flexible membrane layer is designed for over 50,000 actuation cycles, ensuring long-term dewatering performance in moisture-critical industries.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure consistent sealing performance in high-pressure Filter Press Plate assemblies?

Fregatte machines each Filter Press Plate to tight flatness tolerances below ±0.3 mm. This prevents uneven sealing and minimizes gasket fatigue. Plates undergo profile verification using coordinate measuring machines (CMM) to ensure sealing faces remain parallel under compressive load. This helps pflegen leak-proof operation during prolonged filtration cycles.

What materials does Frigate use to improve chemical resistance of Filter Press Plates in corrosive environments?

Fregatte uses virgin polypropylene, glass-filled polymers, and PVDF based on chemical exposure. These materials resist swelling, softening, or stress cracking in aggressive pH conditions. Each batch is tested for elongation, hardness, and thermal stability. Material compatibility charts are also provided to guide selection for specific media.

How does Frigate handle custom configurations of Filter Press Plates for non-standard press sizes?

Frigate supports custom tooling for both recessed and membrane plate profiles. Plate dimensions, feed eye locations, and gasket grooves are machined per customer specs. CAD/CAM systems ensure genaue reproduction of legacy or OEM patterns. This reduces integration risk and downtime during retrofit or scale-up.

How does Frigate address uneven cake formation in large chamber Filter Press Plates?

Frigate designs each Filter Press Plate with optimized drainage geometry to ensure equal slurry distribution. Rib layout and inlet flow routing are simulated using CFD tools. This prevents blind spots and promotes even cake build-up across the plate area. Uniform cake thickness improves dewatering and discharge efficiency.

How are Frigate Filter Press Plates tested for long-term performance under cyclic loading?

Plates are pressure tested up to 1.5× their rated capacity to simulate peak operating loads. Frigate also conducts cyclic fatigue testing across 10,000+ press-open-close cycles. Mechanical degradation, warpage, and sealing performance are evaluated post-cycle. This ensures structural reliability for high-volume, continuous-duty operations.
