Bernoulli - Strainer
Many industrial processes need pure water, free from particles
and other impurities. Modern water supplies are often severely
polluted and this makes heavy demands on purification and
filtration equipment. A good system has to be simple, efficient
and reliable. What is more, it has to be able to withstand
sea water and resist corrosion. The name of this system is
New filter technology
The Bernoulli Strainer is an ingenious design for straining
water. The strainer works on Bernoulli’s principle,
the 250-year-old discovery that an increase in the velocity
of flow of a liquid gives rise to a drop in pressure. A specially
designed piston is introduced into the strainer basket which
creates an increase in the velocity of flow between the piston
and the wall of the strainer. The resulting drop in pressure,
“vacuums“ away the particles which have attached
themselves to the inside of the basket. The impurities are
flushed out through a flushing valve, and problems due to
the clogging of the strainer surfaces are avoided.
The design is simple and robust, giving benefits such as increased
reliability, ease of maintenance and a high level of operational
reliability. Thanks to the right choice of materials and a
well-thought-out design, the Bernoulli Strainer offers a long-life
solution to corrosion problems, even in salt water systems.
Its smooth flow, high capacity characteristics, combined with
low flushing losses, make the filter highly efficient, and
offer real advantages in process system design.
• Continuous operation - the Bernoulli Filter is designed
for continuous operation without interruptions and does not
require any regular maintenance.
• Low pressure drop even for high flow rates
• Low flushing pressure - 0,3 bar pressure gauge is
• Easy installation - the Bernoulli Filter can be fitted
directly to pipe lines. Any horizontal or vertical position
• Good corrosion resistance - the Bernoulli Filter has
a stainless steel, PVC or glass fibre body, particularly suitable
for corrosive liquids such as sea water.
