PURPOSE
If the basket strainer is being used for protection rather than direct filtration, Apollo’s
standard screens will suffice in most applications.
SERVICE
With services that require extremely sturdy screens, such as high pressure/ temperature
applications or services with high viscosities, Apollo® recommends that perforated screens
without mesh liners be used. If mesh is required to obtain a certain level of filtration, then
Apollo recommends a trapped perf./mesh/perf. combination.
FILTRATION LEVEL
When choosing a perf. or a mesh/perf. combination attention should be given to ensure
overstraining does not occur. As a general rule the specified level of filtration should be no
smaller than half the size of the particle to be removed. If too fine a filtration is specified
the pressure drop through the strainer will increase very rapidly, possibly causing damage
to the basket.
