Sieves and filters are important
process engineering devices that are
applied in almost any areas of
modern industry. Their reliability
mainly depends on the condition of
their surface. Thus, sieves and filters
need frequently to be cleaned.
In this area, the WOMA high-pressure
water jet technology is successfully
used since more than 30 years for the
following applications:
|
 |
Removal of incrustations and impurities from sieves and filters. |
|
Cleaning of candle filters in the ammonium industry. |
|
Cleaning of viscose filters in the synthetic fiber industry. |
|
Cleaning of filter clothes. |
|
Calcium removal from sieve suction-rollers. |
|
Removal of deposits from hurdles in the brewer industry. |
|
Cleaning of long- and roundsieves. |
|
Cleaning of plastic sieves. |
|
Cleaning of wet feltings. |
|
Removal of impurities from drainage filter presses. |
Why High-Pressure Water Jets? |
|
Very wide range of applications in all areas of cleaning. |
|
Very wide range of tools and accessories. |
|
High efficiency even in areas of difficult access. |
|
Excellent cleaning quality. |
|
Small tool dimensions and low weight. |
|
Possibility of mechanization of the cleaning tools. |
|
Disburdening of operators from manual, dirty and insanitary jobs. |
|
Avoidance of any gas and slags. |
|
Very sensitive and selective removal of coatings, impurities and deposits without damaging the base materials. |
|
Applications possible during active production. |
The Material Range |
|
Using high-pressure water jets,
among others, the following materials
can reliably be removed from sieves
and filters: Calcified agents, coatings,
deposits, germs, impurities,
incrustations, lacquers, oxide layers,
paint systems, slurries.

The Technique |
|
WOMA offers stationary and mobile
high- and ultra-high pressure water
jetting systems with operating pressures
up to 3,000 bar and water flow rates
up to 1679 l/min, consisting of electric
or combustion drive, high pressure
plunger pump, guiding and control
devices, water tools, and high-pressure
accessory.
Furthermore, WOMA offers
hot waterjetting systems with operating
pressures up to 800 bar and mobile
compact systems with operating pressures
up to 1,000 bar. For operating
pressures up to 400 bar, abrasive resistant
high-pressure pumps (ARP®) are
available for running impurified water.
The special high-pressure program for
sieve and filter cleaning also includes
the following components:
|
|
High-pressure guns in modular design for cleaning and selective material removal. |
|
Pneumatically driven traverse systems. |
|
Electrically driven traverse systems with splash water protection and isolating box. |
|
Nozzle beams and traverse tubes. |
|
Flexible high-pressure hoses. |
|
Round and fan shape nozzles. |
|
High-pressure valves for impurified water. |
