Overview
The G Series Chamber Filter Press and GYM High-Pressure Membrane Chamber Filter Pressrepresent two proven solid–liquid separation solutions designed to meet different levels of dewatering efficiency, operational intensity, and investment requirements across mining, metallurgy, chemical processing, and environmental protection industries.
While both models are based on the classical plate-and-frame filtration principle, they differ significantly in dewatering depth, cycle efficiency, and energy utilization. Together, they form a flexible filtration product portfolio capable of covering basic filtration demands as well as advanced deep-dewatering applications under increasingly stringent environmental and cost-control standards.

G Series Chamber Filter Press
The G Series Chamber Filter Press is a time-tested intermittent solid–liquid separation system known for its high filtration pressure, low cake moisture, robust structure, and reliable operation. It operates by forming sealed filter chambers between adjacent filter plates. Slurry is pumped into the chambers under high pressure, where solid particles are retained on the filter cloth to form a compact filter cake, while the filtrate passes through the cloth and drainage channels for collection.
As a fundamental yet highly reliable dewatering solution, the chamber filter press has been widely adopted in mining, chemical, and environmental industries for decades. It is especially suitable for applications requiring relatively dry filter cakes while maintaining controlled capital investment and straightforward maintenance.
Key characteristics of the G Series Chamber Filter Press include:
High mechanical strength frame structure ensuring stable long-term operation
High filtration pressure resulting in dense filter cakes
Simple operating principle with proven reliability
Strong adaptability to different slurry concentrations and particle sizes
Low maintenance cost and excellent spare-part interchangeability
GYM High-Pressure Membrane Chamber Filter Press
The GYM High-Pressure Membrane Chamber Filter Pressis an advanced evolution of the traditional chamber filter press, often regarded as a deep dewatering specialist. It integrates flexible membrane filter plates into the standard filtration process, enabling a secondary high-pressure squeezing stage after initial filtration.
Following the conventional filtration phase, high-pressure water or compressed air is introduced into the membrane cavity behind the elastic diaphragm. The membrane expands uniformly, applying additional pressure directly onto the filter cake. This secondary compression effectively removes capillary and bound water that cannot be eliminated through filtration alone.
As a result, the membrane filter press achieves:
Significantly lower cake moisture content
Shorter filtration cycles
Higher throughput per unit time
Reduced washing and drying energy consumption
This technology is particularly advantageous for fine-grained, sticky, or difficult-to-dewater materials and is widely used in modern tailings management, sludge minimization, and high-value product recovery processes.
