JVK Filter Elements have been well
proved in all industrial processes since 1962. From that time the development
in the filtration technology on the field of solid-liquid-separation has
been highly influenced by
JVK's new ideas and constructions.
JVK is offering long-term experience on the development,
production and application of filter elements.
JVK filter elements are
successfully used world-wide due
to the high quality standard and the continuous developments.
The specialities of JVK, however, are filter elements being
installed within:
- filter presses
- pressure filters
- vacuum tank filters
- vacuum rotary filters
- electrolysis
- micro filtration
ADVANTAGES OF THE PRODUCTS
The effectiveness of a filter apparatus depends on the construction and
the material of the filter medium support tray. Some common materials
are wood, aluminium, cast iron, ductile iron, stainless steel and material
compounds out of steel and rubber. These elements are showing a lot of
disadvantages as for example low chemical and corrosion resistance, high
weight , unfavourable drainage, considerable abrasion, limited working
life, fluid absorbency and bad sealing.

Plate - Polypropylene Plate |

In 1962 JVK's former company, Messrs. JOH.JAC.VOWINCKEL was
the first to start the production of
polyolefin filter elements in the filtration field of application.
Even today filter plates manufactured at that time are still in operation.
During the 60ties the development of technical thermoplastic
materials lead to the first exchange of the wooden filter elements.
Polypropylene turned out to be the best material due to it's most
favourable price-power-performance and its interesting
combination of excellent properties.
PROPERTIES OF THE POLYPROPYLENE FILTER PLATES
Highest Chemical Resistance
excludes corrosion or damage of the material and
grants a long working life
Improved Product Quality
due to a very good drainage and effective cake washing essentially due
to
the water resistant, non absorbent surface
Excellent Sealing
of chambers avoids losses in product, odorous
annoyance as well as unhealthy gas leakage,
keeping the plant clean
Less Cloth Stress
means longer working life of filter cloth >
Heat Insulation
reduces dissipation of heat towards outside and
saves energy
Less Weight
makes handling of the filter elements easier
Recycling Ability
of older plate designs to a new version with an
adequate additional stabilisation of the used
material
JVK-ICM-PROCESS
JVK produces each kind of filter element for filtration
equipment in accordance with DIN standards or as special designs to meet
all the requirements of each customer. This production is done with the
most modern technical ICM process developed by
JVK.
The
ICM Process, developed by
JVK,
allows to fill the mould computer controlled with premelted homogeneous
thermoplastic
materials.
All
JVK plates are moulded in one piece without any
inserted PP parts or joints. Therefore
JVK products
are most resistant against unbalanced pressure in the chambers
during application.
This process creates products with:
- reproducible controllable mould filling
- a complete homogenous material structure
- minimal thermal damage during processing
- a surface without thermal decomposition
- minimum internal tension due to uniform set up
- best mechanical properties because of an extremely
small crystallite
structure
- chemical resistance even at high temperatures
