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. ºC 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 ¾” and and RC-2 / RCV-2 with 1 ½”

nozzle

6. Components

6.1 Shaft seal

Mechanical seal is supplied as standard for biggest sizes. ForRC-00 and RC-01- shaft seal is by means of several lip seals.

6.2 Driv 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, RC–1 ½ and RC–2, the shafts and gearsare supported by removable friction bearings housed in the

side covers.On the models RC-2R, RC–2RD, RC–3R and RC–4R, 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
