Note
On pump models with stuffing box, the stuffing box may be readjusted in case
of leakage due to higher wear.
To do so, tighten locking screw by an appropriate tool.

Commissioning

Before starting operation:
• Make sure that the supply voltage corresponds to the voltage indicated on the name
plate.
• When using compressed air motors, please do not exceed the maximum operating
pressure of 6 bars and use a filter-regulator-lubricator unit.
• When using compressed air motors, adjust the speed by a ball valve in the air supply
line. Do not exceed the maximum speed of 1000 rpm.
• Before inserting the electrical plug into the socket, ensure that the Start/Stop switch is
set to "0" (Stop). On compressed air motors, close the valve in the air supply line.
• Immerse the pump into the liquid and secure it in a vertical position by the use of a
compression gland or a container clamp.
• Immerse the flexible hose end into the container to be filled and secure it by an
appropriate device.

The outer tube and the stator housing of the pump are marked with the explosion class.
The stator in PTFE white may not be mounted into a stator housing marked "IIB".
The stator in PTFE white may not be used in conjunction with an outer tube marked "IIB".

3.1.1 Definition of explosion-proof protection:

Category 1 (ZONE 0): The external part of the pump between the pump suction end and its
outlet connection.
Category 2 (ZONE 1): The external part of the pump between its outlet and the connection
part to the drive motor as well as the internal part of the pump. (During pumping, the
