A Chamber Filter Press (Recessed Plate Filter Press) is the most reliable, cost-effective, and widely utilized solid-liquid separation equipment in heavy industry. By utilizing chamber filter plates that form sealed chambers when clamped together, these machines rely on high-pressure feed pumps to force slurry into the cavities, efficiently separating clear filtrate from dense solid cakes.
As a leading source factory, Yuwei Filtration Equipment manufactures a versatile range of chamber filter presses, including Fully Automatic Mud Sewage Presses with Cloth Washing Systems, High-Pressure Round Plate Presses for ceramic/clay sludge, and specialized Cast Iron or PP/Stainless Steel Coated Presses for high-temperature and highly corrosive chemical applications. From standard 870mm models to heavy-duty 2000mm industrial units, we provide end-to-end ODM/OEM engineering solutions to maximize your dewatering efficiency.
The Chamber Filter Press represents the backbone of mechanical dewatering. Unlike plate and frame configurations, a chamber filter press utilizes individual plates with recessed (concave) surfaces on both sides. When a hydraulic cylinder clamps these plates together, the recesses form solid, leak-proof chambers. Slurry is pumped into these chambers at high pressure, where the filter cloth captures the suspended solids to build a uniform filter cake, while the clean filtrate exits through drainage ports.
Why do industrial facilities worldwide rely on chamber filter presses for bulk slurry processing? The design offers several inherent mechanical and operational benefits over alternative dewatering methods (such as centrifuges or belt presses):
Yuwei Filtration Equipment engineers various specialized chamber presses to handle the unique physical and chemical properties of different industrial slurries:
Proper sizing is critical for achieving your targeted daily throughput. Below is a standard reference matrix for our industrial chamber filter presses. (Note: Custom capacities and chamber volumes are available upon request.)
| Filter Plate Size (mm) | Filtration Area Range (m²) | Filter Chamber Volume (L) | Standard Cake Thickness (mm) | Motor Power (Kw) |
|---|---|---|---|---|
| 870 * 870 | 30m² – 80m² | 498L – 1287L | ≤35mm | 2.2 Kw |
| 1000 * 1000 | 50m² – 120m² | 776L – 1941L | ≤35mm | 4.0 Kw |
| 1250 * 1250 | 80m² – 250m² | 1560L – 4783L | ≤40mm | 5.5 Kw |
| 1500 * 1500 | 200m² – 500m² | 3809L – 9446L | ≤40mm | 11.0 Kw |
| 2000 * 2000 | 600m² – 1000m² | 11901L – 19651L | ≤40mm | 15.0 Kw |
Critical Logistics and Installation Notice: When reviewing heavy machinery specifications, procurement teams must carefully distinguish between processing capacity and equipment weight. For structural foundation engineering, shipping, and crane lifting purposes, the Operating Weight refers exclusively to the machine’s static physical mass (which can exceed 50,000 Kg for our largest 2000mm models). This static weight guarantees the structural stability required to withstand 18MPa of hydraulic clamping force. It does not refer to the machine’s hourly throughput capacity, which is dictated by the filtration area, feed pump pressure, and specific slurry resistance.
When customizing a chamber filter press, engineers must choose between two filtrate discharge configurations based on environmental and chemical safety requirements:
A Plate and Frame press uses alternating flat solid plates and hollow frame pieces. A Chamber press uses a single type of plate that has a recessed cavity. Chamber presses are significantly more robust, can handle much higher feeding pressures without breaking, and are much easier to automate for rapid cake discharge. Plate and Frame presses are generally reserved for very fine depth filtration using filter paper, such as in the food and beverage industry.
Standard reinforced polypropylene (PP) plates can handle temperatures up to 80°C (176°F). For high-temperature applications up to 120°C, we provide glass-fiber reinforced PP plates. For extreme temperatures reaching up to 300°C (such as waste oil, hot resins, or liquid sugar syrups), we supply heavy-duty Cast Iron or Ductile Iron filter presses.
Instead of operators manually pulling apart heavy plates one by one to release the filter cakes, our automatic plate shifting system uses a motorized carriage on the sidebars. Once the hydraulic cylinder retracts, the carriage hooks onto the plate handles, sequentially pulling them apart at a set speed. This drastically reduces turnaround time and labor intensity, especially on large 1250mm or 1500mm machines.
Our standard PP chamber filter presses comfortably operate at feed pump pressures of 0.6 MPa to 1.2 MPa. For highly resistant slurries, we engineer high-pressure models capable of 1.5 MPa to 2.5 MPa. Our specialized High-Pressure Round Plate presses can withstand even greater forces to squeeze out maximum moisture from difficult materials like clay.
