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 Filters 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 left, has other outstanding advantages. Its Dual Filtration feature provides superior filtering with longer element life. Initial filtration is within this sleeve is the fine Marvel Synclinal element (C). Other available filter element media are shown in Table II .
Marvelbo-R Filter with Colorator Indicator is ideal for all types of filtering applications in all fields.
The Marvelbo-SC and SCB continuous flow in the tank suction indicating filters are economical to purchase install, use and service with uninterrupted operations. The self priming design, eliminates the need for air bleeding, and the mess of draining conventional filters. The use of long life element reduces maintenance cost. Tank mount filter installation instruction and sizing information are in the detailed drawing page .
The filter element can be serviced easily and quickly; simply remove 4 screws, lift off the cover... and the element comes off with the cover assembly... no fishing around in the oil for a submerged element. Snap the replacement or cleaned element into the shroud assembly and reinstall. It is automatically guided into proper position. The element is centered by the element guide so that it slips quickly and easily onto the outlet port. Nothing is required to be closed, reopened, reset or checked after the cover has been reinstalled. And while the cover is off, the filter outlet port is protected by an expanded metal guard.
The unique shrouded element design enables use of generous size elements for long life, minimum servicing frequency and low pressure drop.
The element shroud allows low oil level operation even below the top of the element giving full element effectiveness to meet pump flow requirements. Contrast this to small, squat elements designs of enshrouded elements which must be entirely below oil level for full element effectiveness.
The famous Colorator Indicating Filter Cover tells as simply as a traffic light in green, yellow and red colors when element service is required. It is recommended that the filter be serviced when the indicator is in the yellow and before it reaches the red band. This will assure full flow filtration at all times.
