The Wilo-Stratos GIGA high-efficiency pumps are glanded pumps
with built-in power adjustment and "Electronic Commutated Motor"
(ECM) technology. The pumps are designed as single-stage low-
pressure centrifugal pumps with flange connection and mechanical
seal.
The pumps can be installed both directly as pipe installation pumps in
sufficiently secured pipes or be placed on a foundation base.
The pump housing is designed as an in-line design; i.e. the suction and
pressure-side flanges are on one axis. All pump housings are provided
with pump support feet. Installation on a foundation base is recom-
mended.
NOTICE:
Blind flanges, which allow the motor impeller unit to be replaced even
in a twin-head pump housing, are available for all pump types/frame
sizes in the Stratos GIGA-D series (see chapter 5.4 "Accessories" on
page 79). A drive can therefore remain in operation while replacing
the motor impeller unit.
The pump housing of the Stratos GIGA B is a spiral pump housing with
flange dimensions in accordance with DIN EN 733. The pump has
cast-on or screwed-on feet.
The electronic module controls the speed of the pump within the
control range that can be adjusted by the setpoint.
The hydraulic output is controlled by differential pressure and the set

control mode.
In all control modes, however, the pump adapts itself continuously to
the changing power requirements of the system, which is the case
especially when thermostatic valves or mixers are used.
The basic advantages of the electronic control are:
• Energy saving at the same time as reduced operating costs
• Reduced number of differential pressure valves required
• Reduction of flow noise

• Modification of the pump to changing operating requirements
