IN-LINE FILTER - What's inside and how
to use and maintain it.
This flush-out
filter type is placed in-line between the supply tank and
a positive displacement pump. It can also be placed in-line after
a centrifugal pump. Sizes from 3/4" to 1 1/2" are rated
to 14 bar 1400 kPa or 200 psi.
Only 3 of the filter elements are
shown: Red 50 mesh while the Blue is 80 mesh and the Green element
100 mesh.
Ensure that the suction size of the
pump matches or is smaller than the filter connections. EXAMPLE:
If the pump has a 32 mm or 1 1/4" suction or inlet then use an
in-line filter with 32 mm or bigger connections.
Leaking? A common fault when the bowl
leaks is to overtighten it. The square profile o-ring in the head
needs replacement. It's a tight fit and make sure it is flush and
square with the head.
Cleaning and reassembly: After cleaning the filter element, always push it into the filter head before screwing on the bowl. If you don't, this is what happens.
The
end is crushed and the dirt gets through to the pump valves and the
nozzle-tips.
THE REAL WORLD.
