6.2 Design of product
• MVI pumps are vertical, high pressure, non-self
priming pumps with inline connection based on
multistage design.
• MVI pumps combine use of both high efficiency
hydraulics and motors.
• All metallic parts in contact with water are made
of stainless steel.
7. Installation and electrical connection
Installation and electrical work in compliance
with any local codes and by qualified personnel
only.
WARNING! Bodily injury!
Existing regulations for the prevention of
accidents must be observed.
WARNING! Electrical shock hazard!
Dangers caused by electrical energy must be
excluded.
7.1 Commissioning
Unpack the pump and dispose of the packaging
in an environmentally responsible manner.
7.2 Installation
The pump must be installed in a dry, well
ventilated and frost-free place. Always refer
to the local or national regulations and codes
relating to the selection of the installation site,
the water and power connections, etc.
CAUTION! Possible damage of the pump!
• It is recommended that any welding and
soldering work be done before installing the
pump.
• Thoroughly flush the system before installing
the pump.
WARNING! Risk of injury due to hot surfaces!
The pump must be positioned so that someone
cannot come into contact with the hot pump
surfaces while in operation.
- Install the pump on a flat concrete block using
appropriate accessories. If possible, use an
insulating material under the concrete block to
avoid any noise and vibration transmission into
the installation.
WARNING! Risk of fall!
The pump must be correctly screwed to the
ground.
- Place the pump where it will be easy to reach, to
facilitate inspection, replacement and removal
work. The pump must always be installed
perfectly upright on a sufficiently heavy concrete
base. Refer to Fig.7a-page 8-Proper Installation
Clearances .
CAUTION! Risk of parts inside the pump!
Take care to remove port covers of the pump
housing before installation.
NOTE: Pumps may be pressure tested before
shipment. Some water may remain in the pump. It
is recommended, for hygienic purposes, rinse the
pump before any use with potable water supply.
- The installation and connection dimensions
(connection flanges and pump footprint) are
given in
Fig. 7b through Fig. 7g (page 9 - 10) -
Flanges/Footprint
.
- Lift the pump carefully so as not to damage the
unit. Please refer to
Fig. 3-page 3-Proper Lifting
for procedures and guidelines.
WARNING! Tipping Hazard!
Vertical multistage pumps may have a high center
of gravity. Make sure to secure the pump firmly to
avoid risks.
WARNING! Risk of Damage!
Do not use the motor lifting lugs when lifting the
entire pump: these are only designed to lift the motor
alone. Refer to
Fig. 3-page 3-Proper Lifting
.
For elevated storage tank and water main
applications please refer to
Figure 7h-page 11 -
Storage tank or water main installation
For well or underground storage tank applications
please refer to
Fig. 7i-page 11-Suction lift
installation
.
-Use a foot valve (component 10 in Fig. 7i -page
11-Suction lift installation ) in case of negative
suction head.
7.3 Pipe connection
- Connect the pump to the system piping. For
flanges refer to Fig. 7b through Fig. 7g (pages
8 - 10) .
NOTE: Using elbows in any installation will
increase the flow resistance. Wide bends will
result in a lower flow resistance.
7.4 Anchoring
- The pump must be secured to a solid foundation
by bolts through the holes in the base plate.
Refer to the mounting footprint drawings in
Fig.
7b through Fig. 7g (pages 8-10) .
- The direction of fluid flow is indicated on the
pump.
- Pump must be installed in such a way that it is
not stressed by the pipework. Use pipe supports
