In industries where separating solids from liquids is essential — such as wastewater treatment, chemical processing, mining, food production, and pharmaceuticals the filter press remains one of the most efficient and dependable filtration systems available. It provides high-capacity dewatering and ensures consistent, high-quality separation performance.
However, investing in a new filter press can be expensive, especially for facilities looking to expand capacity or replace existing units. That’s where used filter presses come in offering the same efficiency, durability, and throughput as new equipment, but at a significantly reduced cost.
At JM Industrial, we specialize in supplying used, unused, and surplus filter presses from leading manufacturers. Each unit is inspected, cleaned, and tested to ensure peak performance, giving customers a cost-effective and sustainable solution for their separation needs.
What Is a Filter Press?
A filter press is a mechanical dewatering device that separates solids and liquids using high pressure. It works by pumping slurry into a series of filter plates lined with cloth. As pressure builds, the liquid passes through the filter media, leaving behind solid particles that form a “filter cake.”
This process produces two outputs:
-
Filtrate (clean liquid): The purified liquid that passes through the cloth.
-
Filter cake (solid residue): The compacted solids that are discharged at the end of the cycle.
Filter presses are widely used because they provide excellent separation efficiency, low operating costs, and the ability to handle a variety of materials — from fine particles to coarse solids.
Why Choose Used Filter Presses?
Significant Cost Savings
Buying a used filter press can save you 40–70% compared to purchasing a new unit — without compromising performance or reliability.
⚙️ Proven Performance
Used equipment from JM Industrial is tested and inspected for mechanical integrity, pressure handling, and filtration efficiency, ensuring dependable operation.
Quick Availability
Unlike new systems that may require long manufacturing lead times, our used filter presses are in stock and ready to ship, reducing downtime and keeping your operations on schedule.
Environmentally Sustainable
Purchasing pre-owned equipment helps reduce manufacturing waste and extends the life cycle of durable machinery — supporting sustainability initiatives.
Lower Depreciation
Used filter presses hold their value better than new units, making them a smart long-term investment.
Types of Filter Presses
At JM Industrial, we carry various types of used filter presses to meet the needs of different applications and materials:
1. Plate and Frame Filter Presses
These are traditional designs featuring alternating plates and frames that create filtration chambers. They are easy to operate, clean, and maintain, making them ideal for laboratory or batch operations.
2. Recessed Chamber Filter Presses
Also known as chamber filter presses, they use recessed plates to form chambers that hold the filter cake. This type is popular for high-volume industrial applications such as wastewater treatment and chemical manufacturing.
3. Membrane (Diaphragm) Filter Presses
These include flexible membranes that can be inflated to squeeze the filter cake, improving moisture removal and reducing cycle times.
4. Automatic Filter Presses
Equipped with automation features like automatic plate shifting, cloth washing, and cake discharge, these systems are ideal for continuous, large-scale operations.
5. Belt Filter Presses
Used for continuous dewatering of sludge and slurry, these presses are often used in wastewater treatment plants and large industrial facilities.
Industrial Applications of Filter Presses
Used filter presses are employed in various industries for efficient and reliable solid-liquid separation, including:
-
Wastewater Treatment: Dewatering sludge and reducing waste disposal costs.
-
Chemical Manufacturing: Clarifying chemicals, pigments, and catalysts.
-
Food and Beverage: Filtering juices, edible oils, sweeteners, and syrups.
-
Pharmaceuticals: Removing impurities from ingredients or formulations.
-
Mining and Minerals: Extracting valuable solids from slurry mixtures.
-
Metals and Plating: Clarifying plating baths and recovering precious metals.
Advantages of Using Filter Presses
✅ High Efficiency
Filter presses produce extremely dry filter cakes and clear filtrate, resulting in effective separation.
✅ Cost-Effective Operation
Once installed, they require minimal maintenance and energy consumption compared to other dewatering systems.
✅ Customizable Capacity
Filter presses are available in various sizes and configurations, making them adaptable to both small and large-scale operations.
✅ Reduced Waste Volume
By removing more moisture from solids, they lower disposal costs and environmental impact.
✅ Improved Product Recovery
Filter presses help maximize yield by recovering valuable solids and minimizing product loss.
