Recessed Plates
are designed for 7, 15, and 20 bar operation (100/225/300psi). They
are available for sidebar or overhead press designs. Mounting hangers
or side handles can accommodate any brand of filter.
Recess
Plate - Open Filtrate:
An Open Filtrate recess plate, discharges filtrate to either a "bib"
located on one side of the plate or via vertical holes along the underside
of the filter plate. Visible filtrate discharge from each chamber
can identify holed filter cloth or retention problems.
Recess
Plate - Closed Filtrate:
Virtually identical to the open filtrate but with the addition of
corner pads. Holes in these corners form a pipe or tube and collect
the filtrate which is discharged to a manifold at the feed end of
the filter press. Spigots may be used to examine the filtrate externally.
Gasketted
Recess Plate:
Filter cloth is installed in grooves within the plate. Grooves containing
'O' ring around the sealing edge and filtrate holes
form a tight seal when the plate pack is closed.
Cloth Support Patterns come in 3 distinct
drainage patterns; pipped, elongated pip and grooved. Grooved drainage
is more common on plate & frame installations. The higher filtration
pressures used with recessed or membrane plates make a pipped design
more desirable. This design provides better support for filter cloth,
allowing filtrate to discharge along the base of the plate with
the least resistance.
