Recessed chamber filter plates
The recessed chamber plate builds the frame into the plate itself. That single-piece design is far more stable than a separate plate and frame, so it runs at much higher filtration pressures.
Cake and plate thickness are chosen to suit your filtration conditions. The polypropylene body resists chemicals and is simple to handle.
Why chamber plates
- Single element, so it costs less than separate plates and frames
- Filtration pressures of up to 50 bar
- Suitable for high filtration temperatures
- Robust design with reinforced edges
- Pipped surface protects the filter cloth and drains evenly
Available as
- Wash and non-wash plates
- Standard chamber plate
- Standard chamber plate without stay boss
470 to 2000 mm
CGR chamber filter plates
CGR stands for caulked, gasketed and recessed. The filter cloth is caulked into a groove in the plate, and an O-ring around the sealing edge and filtrate ports closes the plate pack tight.
Groove widths are typically 1/4 to 3/8 inch. The pipped polypropylene surface supports the cloth across the whole drainage area.
Why CGR plates
- Excellent sealing for virtually leak-free operation
- Polypropylene resists chemicals, corrosion and high temperatures
- Handles high pressure and flow
- Pipped surface protects and supports the filter cloth
- Long service life
610 to 1200 mm
Plate and frame filter plates
Plate and frame is the oldest way to separate solids from liquids, and still the right one where cake washing and hygiene matter most. Once made of wood, plates and frames are now moulded in plastic for chemical resistance and easy cleaning.
Symmetrical cake chambers give excellent wash results, and interchangeable frames let you change cake thickness simply and at low cost. Typical users are pharmaceutical producers, including blood plasma, and food processors.
Why plate and frame
- Good wash results
- Cake thicknesses of up to 60 mm
- Easily exchangeable cloths
- Works with disposable filters such as paper
- Works with depth filter sheets
800, 1000, 1200 and 1500 mm
Membrane filter plates
Membrane plates are built like recessed chamber plates, but the drainage surface is flexible. After filtration, air pressure behind the membrane squeezes the cake and presses out remaining moisture before discharge.
Membrane plate vs chamber plate
- Shorter cycle time
- Increased dry solids
- Reduced filtration time
- Reduced cake washing time
- Less wash water
- Increased capacity
- Lower waste disposal cost
- Lower operating cost
- Excellent cake discharge
- Higher quality, higher value end product
- Membranes are easily replaceable
- Membranes are common to either side of the plate
- Pip-style drainage surface for uniform flex
Available as
- Membrane centre feed plate
- Membrane companion plate

Filter Plates: common questions
What sizes of PP filter plates does PAM manufacture?
PAM moulds polypropylene filter plates from 250 mm to 2000 mm. Recessed chamber plates cover 250 to 2000 mm, CGR plates 470 to 2000 mm, plate and frame 610 to 1200 mm, and membrane plates 800, 1000, 1200 and 1500 mm.
What does CGR mean on a filter plate?
CGR means caulked, gasketed and recessed. The filter cloth is caulked into a groove in the plate and an O-ring seals the edge and filtrate ports, which gives virtually leak-free operation.
What is the difference between a membrane plate and a recessed chamber plate?
Both form a chamber for the filter cake. A membrane plate adds a flexible drainage surface that is inflated after filtration to squeeze the cake. That gives drier solids, a shorter cycle and less wash water than a chamber plate alone.
What pressure can recessed chamber filter plates handle?
PAM recessed chamber plates are designed for filtration pressures of up to 50 bar, and are suitable for high filtration temperatures.
Can PAM make a replacement plate for an existing filter press?
Yes. Along with catalogue sizes, PAM moulds adapter plates, thicker plates and round plates. Send the plate size, type and a drawing or sample and the team will confirm the match.
