BAC pumps are non self-priming, single-stage centrifugal pumps in a
horizontal monobloc construction. The suction port is arranged in an
axial orientation and the pressure port is arranged in a radial orienta-
tion. They are equipped with an air cooled motor. The pump housing
is made of composite, and depending on the power, the pumps are
fitted with "Victaulic" and/or threaded unions. The shaft is sealed
with a mechanical seal that does not need any maintenance..
DANGER! Danger of death!
Incorrect installation and improper electrical connections can
result in a risk of fatal injury.
• Have the electrical connections established by approved electri-
cians only, in compliance with the applicable regulations.
• Accident prevention regulations must be observed!
CAUTION! Risk of property damage!
Danger of damage due to incorrect handling.
• Have the pump installed by qualified personnel only.
• Unpack the pump and dispose of the packaging in an environmen-
tally-responsible manner.
CAUTION! Risk of damage to the pump!
Dirt can cause pump failure.
• The pump should only be installed after completion of all welding
and soldering work and, if necessary, flushing of the pipe system.
WARNING! Risk of burns to the pump when body parts come into
contact with the pump!
Depending on the pump or system operating conditions (fluid tem-
perature), the entire pump can become very hot.
• The pump must be positioned in a way that nobody will come into
contact with the hot pump surfaces during operation.
