Marvelbo-SC and SCB Series

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 below .

  • Permits Filter servicing without machine shutdown.
  • Eliminates the conventional filter housing because it mounts inside the reservoir... saves space, weight, installation, and filter costs.
  • Large, long life element reduces servicing frequency, lowers pressure drop and permits finer filtration.
  • Self priming design eliminates need for air bleed.
  • Wide choice of cleanable or throw-away filter elements.
  • Designed for low minimum oil level operation.
  • Thumb screws permit filter service without tools. (SC Series only.)
  • Eliminates mess of draining conventional filters...does away with priming problems.
  • Element shroud permits low oil level operation with full element effectiveness.
  • Famous Colorator Indicator reads element condition as well as magnetic element condition. (Magnets optional )
  • Filter may be sized as large as desired without danger of oversizing and pump priming problems.
  • Reduces suction line air leaks as outlet port is below oil.
  • Standard size element fits same size Marvel Colorator Suction, return line or pressure filter .
  • Available with optional electric warning switch and/or "T" Type dual port outlet for convenient piping when filtering oil to two pumps from the same filter.

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.

Marvelbo-SC and SCB are continuous flow in the tank suction indicating filters that permit servicing with uninterrupted machine operations. Long life elements reduce your time spent on servicing. The self priming design, eliminates the need for air bleeding, and the mess of draining conventional filters. Please see our wide range of cleanable or throw away filter elements. Tank mount installation instruction and sizing information on this page.

INSTALLATION OF MARVELBO-SC AND SCB SERIES CONTINUOUS FLOW FILTER
Simply weld the filter to the reservoir as shown below, positioning the outlet port as desired. An optional bolted mounting flange is also available, however, the selded flange installation is more economical and is recommended.

HOW TO SIZE THE MARVELBO-SC and SCB SERIES FILTER

The total pressure drop through the filter and the suction line should not exceed what the pump can tolerate continuously. Whenever possible it is recommended that for maximum element life, the pressure drop through the filter, when clean, not exceed 0.5 P.S.I. using the 2 P.S.I. by-pass valve, and 1 P.S.I. using the 3 P.S.I. by-pass valve. The 2 P.S.1. by-pass 2 P.S.1. The filter should be cleaned before the indicator moves into the red band to avoid exceeding safe pressure drop limits and to prevent pump cavitation. The above pressure drop figures must be added to the suction line pressure drop to determine the total pressure drop to which the pump is
being subjected.
