Description and function
6.1
Description of the product
The single-stage centrifugal pump is equipped with a directly flanged
motor and a one-piece shaft (monobloc design). The steel pump
housing has an in-line construction, i.e. the suction and pressure
ports lie along a straight line. The pump is designed as an in-line
pump. The pump weight and the position of its centre of gravity ena-
ble all pump sizes to be attached directly to the piping. This requires
the pipe to be appropriately secured to the structure. The pump shaft
is sealed by a mechanical seal for temperatures of up to +210 °C
(IPH-W) or +350 °C (IPH-O). It is cooled by means of the housing
cover's cooling fins.
In conjunction with a control device (Wilo-VR system or Wilo-CC
system), the power of the pumps can be continuously controlled.
This allows optimisation of the pump output for the demands of the
installation and economically efficient pump operation.

Installation and electrical connection
Safety
DANGER! Risk of fatal injury!
Incorrect installation and improper electrical connections can be
life-threatening.
• Have the electrical connections established by approved electri-
cians only, in compliance with the applicable regulations!
• Adhere to regulations for accident prevention!
DANGER! Risk of fatal injury!
Failure to install safety devices on the motor, terminal box or on
the coupling can cause electrical shock or contact with rotating
parts, potentially resulting in life-threatening injuries.
• Before commissioning and after maintenance work, all safety
devices (such as terminal box covers or coupling covers) that were
removed must be reinstalled.
• Keep a safe distance during commissioning.
• Always wear protective clothing, protective gloves and protective
goggles when working.
WARNING! Risk of injury due to the weight of the pump!
The pump itself and pump parts can be extremely heavy. Falling
parts pose a risk of cuts, crush injuries, bruises or impacts, which
may lead to death.
• Always use suitable lifting equipment and secure parts against fall-
ing.
• When performing installation and maintenance work, protect the
pump components against falling.
• Never stand underneath a suspended load.
CAUTION! Risk of material damage!
Danger of damage due to incorrect handling.
• Have the pump installed by qualified personnel only.

Installation
Preparation
• The pump should only be installed after completion of all welding and
soldering work and, if necessary, flushing of the pipe system. Dirt can
cause the pump to fail.
• Standard pumps must be protected from the weather and installed in
a frost/dust-free, well-ventilated environment which is not poten-
tially explosive.
• Install the pump in a place that is easy to access so that subsequent
inspections, maintenance (e.g. mechanical seal) or replacement is
easily possible.
