DANGER ! Due to high position of centre of gravity and small
ground surface of this type of pumps, beware of unstability
during handling to avoid any falling down and take necessary means
to avoid injuries or damaging.
CAUTION ! Handle the pump carefully so as not to alter the
geometry and the alignment of the hydraulic unit.

4.2 Pump and motor
• Multistage vertical pump with wet rotor motor not self-priming, with
ports in line on the same axis in bottom part.
• Wet rotor motor fitted with its converter in its upper part.
• Protection index motor-converter : IP44
• Insulation class : F
• Operating frequencies : 50/60Hz
• Operating voltages : 400V +/- 10%
• Hydraulic connection : Oval flanges on the PN 16 pump casing:
pump supplied with oval cast iron counter flanges for screw-on
tube, rings and bolts.
CAUTION ! Only pump running under pressure.
4.4 Accessories (optionals)
Accessories must be ordered separately
• Insulating valves • bladder or galvanised tank • tank for antihammer
blow effect • weld-on (Steel) or screw-on (Stainless Steel) counter flan-
ge • non-return valves (with nose or spring ring when operating in
mode 2) • vibrationless sleeves • protection kit against dry-running •
sensor kit for pressure regulation (accuracy : ≤ 1% ; use between 30 %
and 100 % of the reading range) • Interface for connection to PLR net-
work • Interface for connection to LONWORKS network.
5. INSTALLATION
Installation and service by qualified personnel only.
5.1 Mounting
• Fig. 1 : pump under pressure on storage tank (7) or town water supply (8).
The liquid flowed by the pump allows the lubrication of thewet
rotormotor bearing and the cooling of the motor-converter. It is
imperative that the suction pressure is upper or equal to 1,2 bar.
So, a running with a storage tank : HC ≥ 2m (Fig. 1) and the venting plug
position : HP ≥ 0,5m.
CAUTION ! Assemble only after finishing all welding and brazing
operations and after thorough cleaning of the pipes. In fact
any dirt can damage the correct operation of the pump.
- Install the pump in a place easy to reach, protected against extre-
ma conditions (rain and sun in excess, frost) and as close as possible
from the drawing point.
- For heavy pumps provide a point of attachment (lifting hook - item
10) in the pump axis (item 12) to facilitate removal.
- Install the pump on a concrete block (at least 10 cm high) (item 11)
and fix with anchor bolts (installation plan see Fig. 3).
- Foresee an insulating material under the concrete block (cork or
reinforced rubber) to avoid any noise and vibration transmission into
the installations.
- Before final tightening of anchor bolts, ensure that the pump axis is
vertical : use shims if necessary.
5.2 Hydraulic connections
CAUTION ! Possible damage of the installation ! The installa-
tion has to bear the pressure reached when the pump runs
at maximum frequency and zero flow rate.
- Pump connection with threaded screw-on tubes directly on the
tapped oval counter flanges delivered with the pump.
- The diameter of the pipe must never be smaller than the one of
the counter flange.
- The direction of the fluid flow is indicated on the identification
label of the pump.
- Use supports or collars (Fig. 1, 2 - item 7) so that the pump does
not bear the weight of the pipes.
CAUTION ! Water potable using !
In order to avoid the proliferation of bacteria, the tank must
be flow-through and equipped with the insulation valve type "flow
jet" (Fig. 2 - item 12).
CAUTION ! Possible damage of the installation !
It is recommended to connect the non-return valve to the
pump discharge to protect it against hammer blow effects.
5.3 Electrical connections
The electric connections and inspections have to be carried
out by a qualified electrician and have to comply with the
relevant local standards.
- The electric characteristics (frequency, voltage, nominal current) of
the motor-converter are mentioned on the nameplate. Check that
the motor-converter complies with the mains supply used.
- The electric protection of the motors is integrated into the conver-
ter. The parameters take into account the characteristics of the
pump and must ensure its protection and the one of the motor.
- In case of impedance between earth and neutral point, install a
protection before motor-converter.
- Provide a fuse disconnecting switch (type GF) or a circuit-breaker
to protect the mains installation (Fig. 1 - item 9).
WARNING ! If you have to install a differential circuit-breaker
for users protection, it must have a delay effect.
CAUTION ! Adjust it according to the current mentioned on
the converter label.
Main network
- Use power cables conforming with standards.
DO NOT FORGET TO CONNECT TO EARTH.
The electric connection of the converter (Fig. 4) according to its
operating modes (see chapter 8 for starting) has to comply with the
schemes of the following table.
CAUTION ! A connection error can damage the converter.
The power cable must never touch the pipe or the pump ; make sure that
it is sheltered from any humidity.
