INSTALLATION
1.1.
Operation principle
In order to operate the pump, the casing has to be filled with liquid before start-up. The
liquid enters the pump casing axially to the shaft. The rotating impeller generates a
centrifugal force accelerating the liquid through the pump casing and into the discharge
piping.
1.2.
Receiving inspection
Although precaution is taken by us when packing and shipping, we urge you to carefully
check the shipment on receipt. Make sure that all parts and accessories listed on the packing
list are accounted for. Immediately report any damage or shortage to the transport company
and to us.
1.3.
Storage
If the equipment is to be stored prior to installation, place it in a clean location. Do not
remove the protective covers from the suction and discharge which have been fastened to
keep pump internals free of debris. Clean the pump thoroughly before installation.
When in storage, turn the shaft by hand at least twice per week. The pump-motor unit should
always be stored indoor in dry, vibration and dust free conditions.
1.4.
Foundation
The pump-motor unit must stand on and be fixed to a sufficiently rigid structure that can
support the entire perimeter on which the unit stands. The foundation on a firm bottom is
the most satisfactory. Once the pump is in position, adjust level with metal shims between
the feet and the surface on which it stands. Check that the feet of the pump motor unit stand
well on each of them. The surface on which the foundation stands must be flat and
horizontal. If the unit is fitted on a steel structure, make sure that it is supported so that the
feet do not warp. In any case, it is advisable to fit some anti-vibration rubber pieces between
the pump and the brickwork. The motor needs an additional stand as its level is higher than
that of the pump casing. As an option the pump can be ordered with feet for the motor. For
close-coupled type, pump motor alignment is not required.
