- EQUIPMENT DESCRIPTION.
RCpumps, RCVpumps(verticalversionof RC) andRCA
pumps are gear displacement pumps with axial in-line
suctionanddelivery.RC-OOandRC-01sizesaresupplied
in close coupled configuration and are not available in
vertical versions.
CLOSE COUPLED
RC (BareshaR)
RCV (VERTICAL)
RCA series pumps include an internal thermal isolation
chamber.
This manual outlines installation In a fixed location.
According to the size and type of pump ordered a
number of pieces may be deliberately omitted such
that certain parts of this manualwill not be applicable
to all pumps. These parts may be, for example:
- Retainers, mechanicalseal or packing gland.
- Roller bearing or friction bearing.
-Type of motor

/1 These pumps are only suitable for clean, solid-free
liquids.
The sound pressure of these pumps is less than 96
dB(A) at any momentof operation(giventhat the flow
is above the minimum requiredfor each model). The
sound power is lessthan 110 dB(A).
4.1. Shafl seal
Models RC-00and RC-01use retainersand all other
models use mechanicalseals or packing-gland.
4.2. Surge or by-pass valve.
All pumps in this family have an internal surge valve
which recirculatesthe liquid if the delivery pressure
exceeds ratedpressure. This protects the pump anc
installationfrom excess pressure.
As aruleof thumbthisvalveshouldbeset to 2 kgtcm'
abovethe pressurestatedinthe orderandshouldnu

-INSTALLATION
The design of the pipework, anchoring and
other parts of the installation is not the
res~onsibilitvof the manufacturer. rrUR offers
information&dsuggestionsby wayofguidelines
only and cannot assume responsibilityfor the
design, assemblyandrunningofaninstallation.

the information supplied by us and thereby
ensure correct running.
5.1.- Mounting
The unitcanbemountedonalargefoundation.
Thisfoundationmustprovideaflat, levelsurface.
The unit is to be attached to this platform by
anchoringboltsdesignedto avoidvibrationcaused
by operation of the pump.
5.1.I.-Anchoring bolts
'Bombas ITUR' can supply the anchoring bolts.
They are fitted as follows:
Mode of use:
- Place the equipment over its base.
- Drillholesinthe baseinthe pointscorresponding
to the anchoring points into which to fnthem.
- Level up the unit.
- Once the equipment is locatedon itsfoundation
andthe boltsarefid intothe holes,pourcement
(do not use quick setting cement) into the holes
and allow 48 hours for it to dry.
- Level up again and tightenthe bolts.
5.1.2.- Levelling up
A conventionalspirit-levelmay be usedto levelupthe
unit.The unit mustbelevelledUDbothlenuthwavsand-crossways.
If it is necessary to level the base plate by using
wedges small pieces of cut sheet metal should be
used. Bondthemwith askinofcementto preventthem
from deformingwhen the bolts are tightened.
Once levellinghas been completed it is wise to fn a
lock-nuttoeachoftheboltssothatthey donotbecome
loose during operation.

Inthe standardversion all RC, RCV and RCA pumps
include a flexible coupling except RC-00 and RC-01
sizes (closecoupled) which have a rigid,coupling.
Equipment supplled in the form of a complete
motor-pumpunitwill already have beenalignedin

The unit mustalwaysbe alignedonce allparts
are assembledandit is readyfor start up.
The correct alignment of the standard ITUR drive

andconcentricbychockingupthe motor as neces-
sary.

5.2.2.- Rigid Coupling
All units are factory aligned and this alignment is
not lost unlessthe unit is dismantled. If this is the
casethe following steps should betaken once re-
assembled:
-Check that all the flange supporting surfaces

- Insert the motor shafl into the pump without
forcingit so as to avoiddamage to the bearings.
- Checkalignmentbetweenbothshaftsturningthe
assembly by hand and measure possible
misalignmentwith a comparator.
5.3.- Plpework unlons
Strain on the pump collar can cause misalignment ol
the flanges. To reduce strain the flanges must be
parallel and concentric. The bolts or studs usedto fix
the flanges must passfreely through the holes drilled
inthem. Donotforgetto placeasealorgasketbetween

.-STARTING AND RUNNING
7.1.- Starting the pump unit
- Before starting the pump unit go through all the
sections of Chapter 6: 'BEFORE START UP'.
- All the valves on the inlet side must be fully opened
andthe outletvalve partiallyclosedbeforestartingthe
pump. Once the pump has reached operating
speed and all air has been eliminatedfrom the inlet,
the pump may be regulated by adjusting the outlet
valve.
- If the motor protector cuts out on start up the outlet
should be closed a little, thereby further restricting
flow, untilthe motor starts normally.
/iThepumpmustNEVERbeoperatedwithareduced
or zero flow as the recirculatingliquidcontainedin
thepump willrapidlyoverheatleadingto the riskof
explosionowingto thehighpressuresthatcanbuild
up within the casing.
A-Do not operate the pump with the suction or
delive~yvalves closed.

7.2.- Checking during running
Durinathe first few M e s of oweration:
Pumpwsh mechanicalseal:
- Check that there is no leakage whatsoever through
the mechanical seal. If there is the seal must be
checked andlor replaced immediately.
Pump sealed with gland packing:
- Ifthere isnoleakagewhatsoeverimmediatelyloosen
the packing gland until it drips slowly.
- If there is excessive leakage leave it to settle for 10
minutesthentightenthe gland 116of atum and leave
to settle for another 5 minutes. Repeatthis process
untila drip rateof between20to 60 drips a minuteis
obtained.
After several hours omration:
- Check the bearing temperature by placing E
thermocouple on the nearest housing. The norma
temperature can reach40°above ambient tempera.

Besure toput eaccofthe partsbackinthe right
place, especially the seal and impeller compo-
nents. 7ighten the impellernutsfully.
0.- LUBRICATION
RCand RCVseriespumpsare Viedwith eitherfriction or
roller bearings which are lubricated by the liquid itself
makingitunnecessaryto takeanyadditionalstepsunless
problems arise.
The models which are fitted with frictionbearings are:
RGOO. RC-01, RC-1, RC-1%. RG2
RCV-1. RCV-1% RCV-2
The models using roller bearingsare:
RCPR, RC2RD, RC9R, RC-4R
The models comprising the RCA series use external
grease lubrication.
Before lubricatingthe pump ensure that
- The pump is stopped and there is no risk of its
accidentally starting.
- The bearinghousingtemperature is lessthan 40°C
so that there isno riskof bumsto the hands. Uses
thermowuple to measuretlts temperature.
10.1.- Greasing (RCA only)
The pump leavesthe factorywiththe bearingsready
greased for the first 1000hours (approx.) operation.
For lubrication purposes a table has been included.
Quantities shown are grams of grease to be applied
to the greasing points approximately every 4000
hours of operation for pumps of the given shaft
diameters (measured on the couplingside).
1; 1 GREASE IQUANTITY(gr)

10.1.1.- Changing the grease.
When changingthe grease the bearings must first
be stripped down and their seats in the base
thoroughly cleaned to remove all traces of the old
grease.

DESMl MODULAR S is a single-stage self-prlmlng,
centrifugal pump wlth stainless steel shaft and me-
chanlcal shafl seal. The small pumps, sizes 532.25
110, 550-32-135,and S50-32-220, have open Impellers,
all other sizes have closed impellers.
The pump Is sultable for clean or polluted liqulds wlth
temperatures ranging from O0 to 60°C.
The pump has horizontal Inlet on the centre llne and
vertical outlet at the top.
The back of the ImpellerIs equippedwlth relief blades
In order to reduce the axlal load on the bearlngs at.
high revolutlons and pressure.
Relief holes in the Impeller ensure circulation of lip
uids for the shafl sealand prevent, under normal cori.
dltlons, overheatlng of the shaft seal.
The Dumos are oartlcuiarlv suitable for the oumolno
of water in connection wlth coollng systems; cool in^
of dlesel englnes. Irrlgatlon, water lowering, and flre
protection,as baliast and biige pumps, and-as pumps
for fish farms, water works, salvage contractors, ar;
mles, and navles.
The pump should be Installed on a base plate with a
fiat surface to avold dlstortlon. The centre llne of the
shaft Is to be horlzontal.
Bore H7 Is recommended If the pump is to be fltted
wlth a V-belt pulley, to facilitate the fitting, the hub
can be heatedto~aboutlOOO~;..~. . ~ ~ ~~- ~~ .~. .. .
The V-belt oullevcanthen easllv beslid onto the shaft
towards the shoulder. ~lternatfvely,a belt pulley wlth
a taper lock bush can be fltted.
When selecting the V-belt pulley,It is lmportant to ob-
serve the lnstructlons glven in the DESMlnomograms
for the pump size In questlon. If In doubt, ask DESMl
to advise.
If the pump Is to be drlven by a motor through a fiexl-
ble coupling, pump and motor should be mounted on
a common base piate.
Please note the followlng:
1. Avold dlstortlon In the base plate.
2; Avold dlstortlon In the piping.
3. Make sure that pump and motor are correctly
allgned.

4. Plplng
The suctlon hose should be fltted very carefully as -)even thy leaks may lmpalr the self-prlmlng. Water-
tightness may be checked by a pressure test.
The suctlon hose should be as short as posslble.
When selectlng make sure that the veloclty of the
water does not exceed 2 mhec.
Use a stralner when PumDlno oolluted Iloulds. The
stralner must be fltted with asieve wlth a'sectlonal
area of flow of 3 x the areaof the stralner. Mesh slze-
see data sheet for pump In questlon.
The pressure hose should be sized for a velocity of
water not exceeding 5 to 6 mlsec. In order to ensure
bleeding of the pump durlng prlmlng It is essential
that the pressure h e Is made so that traps in the
pipework'are avolded. During prlmlng the pump can-
not produce enough pressure to overcome traps.
The plplng should be arranged so that posslble
stresses resuitlng from~fluctuatlonsIn temperature
are not applied to the pump.
Tools for Dismantling and Assembllng of Pump

5. Startlng
5.1 Llquld Filllng
A self-prlmlng pump must flrst be fllled with llquid.
Llquld fllllng takes place at the top of the pump
caslng. Remove the plug, flll the pump, replace the
plug, and the pump Is ready for use.
The liquid also serves as coolant for the shaft seal.
5.2 Start-up
Before start-up do the following:
1. Check that the shaft can rotate freely.
2. Check that the pump caslng Is fllled with water.
3. Start the pump for a moment to check the direc-
tlon of rotation.
If the dlrectlon Is correct (clockwise when viewed
from shaft end) the pump may be started.
6. Lining-up
It is often dlfflcult to calculate the manometrlc dellv-
ery head In advance. It Is, however, declslvely lmpor-
tant for the quantlty of llquld dellvered.
3I
A considerably smaller dellvery head than expected
.will increase the quantlty of llquld dellvered, causlng
Increased power consumption, motor overload, and
perhaps cavltatlon In the pump and the piping. The
Impeller may show slgns of heavy eroslon caused by
cavltatlon (corroslon), whlch may at tlmes render an
impeller unfit for use In a very short tlme. Not unusu-
ally do slrnllar eroslons occur in pipe bends and
valves elsewhere In the plplng system.
Therefore, it Is necessaryto check either the quantlty
of llquld dellvered or the Dower consum~tionof the
pump, e.g. by measuring v'oltage and curient level on
the motor. Together wlth a readlng of the counter
pressure a determinatlon of the ouantltv of water de-
ilvered can be compared agalnsi the characterlstlcs
of the pump.
Should the pump not functlon as Intended, please
proceed accordlng to the followlng fault-flndlng list.
Bear In mind. thouoh. that the ourno was carefullv
checked and testedit'our factoG and that the malo;-
Ity of faults stem from the plplng system.
