Suction Line Filter - Sump Filters
Sump filters and suction filters provide critical initial protection for the pump, aiding in protection for the rest of
the hydraulic system. Sump filters which are mounted inside the hydraulic reservoir or tank, are the most
economical filters. Suction line filters are mounted outside the reservoir to simplify cleaning and often employ
visual and/or electrical indicators.

Marvel Engineering suction filters come in
external mount visual electrical indicating versions, reservoir top
mounted continuous flow colorator styles and in tank strainers that include take apart type filters.
The Marvelbo-S Suction Filter with Colorator Indicator, (A) in cut-away at
