• The drive rating plate is on the electronic module on the side with the
cable bushings (Fig. 12, Item 3). The electrical connection is to be
made in accordance with the specifications on the drive rating plate.
The pump has the following main functional assemblies:
• Hydraulic unit (Fig. 6, Item 1), consisting of the pump housing, impel-
ler (Fig. 6, Item 6) and lantern (Fig. 6, Item 7).
• Optional differential pressure sensor (Fig. 6, Item 2) with connecting
and fastening parts.
• Drive (Fig. 6, Item 3), consisting of the EC motor (Fig. 6, Item 4) and
electronic module (Fig. 6, Item 5).
Due to the continuous motor shaft, the hydraulic unit is not a ready-
to-install kit; it is disassembled during most maintenance and repair
work.
The hydraulic unit is driven by the EC motor (Fig. 6, Item 4), which is
controlled from the electronic module (Fig. 6, Item 5).
As far as the assembly is concerned, the impeller (Fig. 6, Item 6) and
the lantern (Fig. 6, Item 7) belong to the motor impeller unit (Fig. 13).
For the following purposes, the motor impeller unit can be separated
from the pump housing (which can remain in the piping) (also see
chapter 10 "Maintenance" on page 110):
• To provide access to the inside parts (impeller and mechanical seal)
• To make it possible to separate the motor from the hydraulic unit.
When this is done, the transport eyes (Fig. 13, Item 2) are removed
from the motor flange (Fig. 13, Item 1), taken to the motor housing
and refastened there with the same screws to the motor housing
(Fig. 13, Item 3).
