ENGLISH
1 - GENERAL
1.1 Applications
Pumps aimed at pumping clear liquids in building, agriculture and
industry areas ...
Water supply, water tower, sprinkling, high pressure washing, fire pro-
tection, boiler supply (with mandatory by-pass kit) – lifting of conden-
sates – air conditioning – industrial networks and integration in all
modular systems.
1.2. Technical characteristics
• Maximum operating pressure :
- Pump casing – PN 25
- Pump casing – PN 16
- Pump casing-rapid hose
coupling for Victaulic bracket
- Maximum suction pressure
• Temperature range :
- Standard versions EPDM O'ring and mechanical
seal (KTW/WRAS approved versions *)
- Versions for aggressive water
(Viton O'ring and mechanical seal )
• Maximum suction head
• Ambient temperature (standard product): + 50° C maxi
• Ambient humidity
* (WRAS : according to British standard - KTW : according to German standard).
2. SAFETY
Read this instruction carefully before installing and starting up. Pay
special attention to the points concerning the safety of the equip-
ment as regards the intermediate or final user.

rial damages.

3. TRANSPORT, HANDLING AND STORAGE

When receiving the material, check that there has been no damage
during the transport. If any defect has been stated, take all necessa-
ry steps with the carrier within the allowed time.
If the delivered material is to be installed later on,
CAUTION !
store it in a dry place and protect it from impacts
and any outside influences (humidity, frost etc...).
Due to high position of centre of gravity and small ground surfa-
ce of this type of pumps, beware of unstability during handling to
avoid any falling down and take necessary means to avoid inju-
ries or damaging.
Handle the pump carefully so as not to alter the goemetry and the
alignment of the unit.

Multistage vertical pump not self-priming, with ports in line on the
same axis in bottom part.
Shaft sealing by standardized mechanical seal.
Hydraulic connection
Oval flanges on the PN 16 pump casing : pump supplied with oval
cast iron counterflanges for screw-on tube, rings and bolts.
Round flanges : pump delivered with rings and bolts without counter-
flanges (accessories as option).
Rapid hose coupling (only 2, 4, 8m3/h) for "Victaulic" bracket : pump
delivered without brackets (accessories as option).
4.3 The motor and its speed variator
Asynchronous motor with standardized flange and shaft end for ver-
tical operation fitted with its speed variator.

4.4 Accessories (as option)
• By-pass kit • insulating valves • bladder or galvanised tank • tank
for antihammer blow effect • weld-on (Steel) or screw-on (Stainless
Steel) counterflange - rapid hose coupling like "Victaulic" • non-return
valves (with nose or spring ring when operating in mode 2) • strainer-
foot valve • vibrationless sleeves • protection kit against dry-running
– sensor kit for pressure regulation (accuracy : ≤ 1% ; use between 30
% and 100 % of the reading range).
5. INSTALLATION
Two standard types :
• Figure 1 : pump in suction
• Figure 2 : pump under pressure on storage tank (item 9) or town
water supply (item 10).
5.1 Installation
Install the pump in a place easy to reach, protected against frost and
as close as possible from the drawing point.
For heavy pumps provide a point of attachment (lifting hook) in the
pump axis (item 12) to facilitate removal.
Install the pump on a concrete block (at least 10 cm high) (item 13)
