2. S FETY
Read this data sheet carefully before installing and starting up. Pay
special attention to the points concerning the safety of the equip-
ment for the intermediate or end user.

material damages.
3. TR NSPORT ND STOR GE
When taking delivery of the equipment, check that it has not been
damaged in transit. If anything is found wrong, take the necessary
steps with the carrier within the allowed time.
If the equipment delivered is to be installed at a
C UTION !
later time, store it in a dry place and protect it from
impacts and outside hazards (moisture, frost, etc.).
Due to high position of centre of gravity and small ground sur-
face of this type of pumps, beware of unstability during hand-
ling to avoid any falling down and take necessary means to
avoid injuries or damaging.
Handle the pump carefully so as not to alter the geometry or align-
ment of the hydraulic assembly.

4.2 The pump
Multistage vertical pump (1 to 16 stages).
Not self-priming.
Ports in line on the same axis in bottom part.
Shaft sealing by standardized mechanical seal.
• Round flanges : pump supplied with gaskets and bolts without
counterflanges (accessories in option).
• Cartridge system for an easier maintenance on MULTI-V 36C/60C
and MULTI-V 80/100.
• "Spacer" feature to avoid big size motor disassembling on MULTI-V
36C/60C and MULTI-V 80/100.
4.3 The motor
Sealed motor with standardized flange and shaft end for vertical
operation.
Motor and pump linked by a coupling with safety guards.
Protection index: IP 55
Insulation class: F
For motor variator fitted on MULTI-VE pumps, see specific
electronic leaflet.

5. INST LL TION
Two standard cases:
• Fig. 1: Pump in suction
• Fig. 2: Pump under pressure from storage tank (item 9) or town
water supply (item 10), with dry-running protection system.
5.1 Installation
Install the pump in a place that is easy to reach, protected from frost,
and as close as possible to the place from which water is drawn.
For heavy pumps, provide a point of attachment (lifting hook, item
12) in the pump centreline to facilitate removal.
Install the pump on a concrete foundation block (item 13) at least 10
cm high and attach by anchor bolts (for installation surface, see Fig. 3).
Place an insulating material (cork or reinforced rubber) under the
concrete block to avoid transmitting noise and vibrations to the rest
of the installation.
Before final tightening of the anchor bolts, make sure that the pump
centreline is quite vertical; use shims if necessary.
