1. Fields of Application
RC pumps are used for pumping viscous and with lubricatingproperties liquids without solids in applications such as:
Marine industry: motor lubrication, fuel feed, fueltransfer and lub-oil transfer.
Oil: mineral and vegetable oils, oil derivates,greases and additives
Petrochemical industry: liquid polymers, viscous
solvents, emulsions, adhesives, fuel oil, diesel oil
Chemical industry: liquid soap paste, soya oil,glycerine,..
Paint and lacquer industry: binders, colouringmatters, solvents, textile dyes
2. Operating Data
50 Hz 60 Hz
Capacity, max. m3/h 78 94
Head, max. m 100 100Operating temp., max. C 80 80
Operating pressure, max. bar 10 10
Operating speed, max. rpm 1500 1800
For any specific application beyond these limits, please consult
KSB ITUR. All data given in this document are for fully standard
construction
3. Design
Double-gear pump, self-priming (1), with in line suction anddischarge. Pump casing with adjustable automatic reliefbypass valve.
Three types:
- Horizontal (sizes from R1 to R4)
- Vertical (sizes from R1 to R4)
- Close coupled (sizes RC-00 and RC-01)
Close coupled Horizontal Vertical (RCV)
(1) with siphon type pipe installation
4. Designation
RC V - 2 R D
*Except RC-00 which has a nozzle of and and RC-2 / RCV-2 with 1
nozzle

6. Components
6.1Shaft seal
Mechanical seal is supplied as standard for biggest sizes. ForRC-00 and RC-01- shaft seal is by means of several lip seals.
6.2Driv e
IEC frame electric motor.
6.3 Bearings / Lubrication
The RC-00 and RC-01 size pumps do not have independentfriction bearing bushes and its upper shaft supports on themotor bearings.
In the models RC-1, RC1 and RC2, the shafts and gearsare supported by removable friction bearings housed in the
side covers.On the models RC-2R, RC2RD, RC3R and RC4R, theyare supported by ball bearings, housed in the intermediatesupport.
In all cases the bearings are lubricated by the pumped fluid..
6.4 Coupling
Flexible, rubber plug type coupling for all pump sizes, exceptfor RC-00 and RC-01, that are close coupled type.
Coupling guard: Metallic protections are supplied asstandard.
6.5 Base Plate
The horizontal pumps, from RC-1 to RC-4R sizes, can besupplied on a base plate or bare shaft.
Base plate: of steel, welded or U-rails for complete unit (pumpand motor).
6.6 Safety valve
All the pumps include an adjustable bypass valve for internalsafety.
Direction of rotation
Fixed as standard. If customer wants to change the direction
of rotation of the gears and thus the the direction of pumpedfluid, contact KSB ITUR for feasibility since modifications tostandard configuration pump must be carried out.
7. Certification
Certified quality management according to ISO-9001
