If the differential pressure becomes too high, the electric motor
switches off at an overpressure of 7 bar (101 psi).
To read out the clogging indicator or to enable it to send a
signal to the controller, a conveyed medium has to flow through
the filter element.
Due to the universal application options of the filter system, it is not possible
to make any statements on the service life of the filter elements. A clogging
indicator is absolutely necessary, especially if medium is often pumped out
of highly contaminated vessels.
This type of filter trolley is equipped with an electrical clogging indicator
which forwards a signal to the controller. When “
change filter
” is shown on
the display, the filter element has to be replaced.
