Common Problem

Drip Leakage & Filtrate Loss

Filtrate dripping between filter press plates causes product loss, workplace contamination, and environmental hazards. CGR (drip-tight) filter cloths provide a gasket-integrated seal that eliminates inter-plate leakage.

The Problem

In filter presses, the filter cloth is clamped between adjacent plates to form sealed chambers. When the cloth does not seal properly against the plate surface, filtrate escapes between the plates — dripping down the press frame, onto the floor, and into the workplace environment.

This drip leakage is more than an aesthetic issue. It represents direct product loss, creates slip hazards, corrodes equipment, and can violate environmental discharge regulations. In chemical and pharmaceutical applications, leaking filtrate may be toxic, acidic, or contain valuable product that cannot be recovered.

Traditional filter cloths rely solely on hydraulic clamping pressure to seal. But plate wear, cloth compression, and uneven surfaces create leak paths that worsen over time. The solution requires a fundamentally different sealing approach.

Consequences of Drip Leakage

Direct product and filtrate loss reducing yield
Workplace contamination and slip/fall hazards
Equipment corrosion from acidic or alkaline drips
Environmental regulation violations and cleanup costs
Increased maintenance for cleaning press frames
Poor workplace hygiene in food and pharma environments
Higher clamping pressures needed, accelerating plate wear

The CGR Solution

CGR (Cloth with Gasket Ring) technology integrates a sealing gasket directly into the filter cloth — creating a drip-tight seal without additional hardware.

Integrated Gasket Ring

A vulcanised rubber or elastomer gasket is bonded directly to the cloth perimeter. When plates close, the gasket compresses into the plate groove, creating a mechanical seal.

Zero Drip Operation

The CGR seal eliminates inter-plate leakage completely. No drips, no product loss, no environmental contamination — even at high filtration pressures up to 16 bar.

Lower Clamping Pressure

The gasket seals at lower hydraulic pressure than cloth-to-plate contact alone. This reduces mechanical stress on plates and extends press frame life.

Custom Gasket Profiles

Gasket shape, hardness (Shore A), and material are matched to your specific plate geometry — recessed chamber, membrane, or plate-and-frame types.

Retrofit Compatible

CGR cloths fit existing filter presses without modification. They replace standard cloths directly — no changes to plates, manifold, or hydraulics needed.

Extended Cloth Life

The gasket protects the cloth edge from abrasion and chemical attack. CGR cloths typically last 20–40% longer than standard cloths in the same application.
