The filtration unit has a gear pump (2.10) that is directly flange-mounted to
the electric motor (6.30) via a coupling.
The supply voltage can be found on the name plate of the unit and on the
name plate on the electric motor (6.30).
Switch the unit on or off using the operating switch (6.10). The thermal
overload protector (6.90) and the connector cable with plug are located at the
terminal box of the electric motor (6.40).
The motor pump assembly is flange-mounted to the connector head. The
connector head has the following components:
A suction strainer (2.42) in the suction port (2.43)
The threaded connection for the filter housing (2.60)
The clogging indicator (2.30) for displaying the differential pressure via
the filter element.
A pressure relief valve (2.50)
