The construction of the JVK
membrane chamber plate
meets all important technical requirements:
Design in accordance to individual requirements
High functional safety
- Basic construction
- Membrane core plates (MTP)
- Press medium
- Membrane installation
- Filter cloth fixing
- General informations
1. Basic Constructions
membrane chamber plates can be supplied in the
- Suspension inlet inside the plate:
center, center top/bottom, in the corner
- Suspension inlet outside the plate
- Corner ports for filtration and cake washing,
inside or outside the filter plate
2. Membrane Core Plate (MTP)
The membrane core plate taking up the membranes is generally produced
out of high molecular, high heat stabilized Polypropylene (PP) in accordance
to the ICM process
developed by JVK
Treatment is done on CNC-milling machines according to DIN standard 7129
and in the narrowest possible
tolerances. It is possible to adapt these plates to all specific requests
of any filtration plant choosing the most suitable materials:
different Polypropylene types, other thermoplastic or metallic materials
e.g. aluminium or ductile iron resp. their combination with other thermoplastic
elastomeres as a surface protection.
Usually there will be installed one detachable elastomere membrane on
each side of the core plate. The membranes are made from vulcanized
or thermoplastic special elastomeres, as for example EPDM, NBR, SBR,
VITON, PP-TPE etc. The design of most critical zones was considered with
care in order to grant a long working life.
4. Press Medium
The gap between the combinationplate and the membrane is inflated by
the pressmedium, e.g. air or water. The cake will be adjustable
compressed and at the same time residual moisture will be reduced. The
press medium as
well as the operating situation determine type and position of connection.
Threaded inserts being frontal fixed on each core plate do allow
an individual connection of the JVK membrane chamber plate to the
manifold of pressure medium.
An internal channel in a suitable position of the sealing area
can connect each JVK membrane chamber plate with
the squeezing media. Sealing is done by an elastomere O-ring
between the plates.
5. Membrane Installation
The membrane must be installed in the sealing rim and support boss area
of the core plate. A detachable fixing is only applied within the feed
area by clamping rings from thermoplastic material as PP, PVDF etc.
The screwless version can be realized using support and distribution
cheme-drawing / membrane installation
6. Filter Cloth Fixing
For any design filter cloths with barrel neck can be used.Overhang filter
cloths can be installed with modified clamping rings or with support
and distribution rings.

7. General Information
The combination of JVK
membrane chamber plate and JVK
chamber plate is approved in all fields of application and much more
in price. There are less limitations compared to more rigid membrane.
Due to the high elastic membrane a filter press completed exclusively
with membrane chamber plates is only necessary in special applications.
||The construction of the JVK membrane
chamber plates is protected by various patents and trademark rights
all over the world.
