Name plates The Wilo-Stratos GIGA has three name plates:
• The pump name plate (Fig. 11, Item 1) includes the serial number
(Ser.-No…/…), which is, for example, required for spare parts ordering.
• The electronic module name plate (electronic module = inverter or
frequency converter) (Fig. 11, Item 2) indicates the designation elec-
tronic module being used.
• The drive name plate is at the inverter on the side with the cable lead-
throughs (Fig. 12, Item 3). The electrical connection is to be made in
accordance with the specifications on the drive name plate.
Functional assemblies 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 EC motor (Fig. 6 , Item 4) and elec-
tronic module (Fig.
6 , Item 5).
The hydraulic unit is not a “ready-to-assemble” assembly due to the
motor shaft which goes through; it is taken apart for most mainte-
nance 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) depend on the motor impeller unit (Fig. 13).
