METAL PUMPS RCEHorizontal Chemical Centrifugal Pumps –

Robust for Sophisticated Fluids.

02

RCETHE ROBUST CHOICE

If you want to solve demanding pumping tasks in the industry efficiently, permanently and economically, you need more than just a coherent technical concept. Experience of application, material knowledge and dialogue with you ultimately lead to the optimum solution. A way which Rheinhütte Pumpen has been following for over 150 years.

THE RIGHT CHOICE FOR DIFFICULT PUMPING ASSIGNMENTS

The particularly robust, horizontal RCE series with a single-stage volute casing

has proven its worth as a chemical pump for many decades now. As a product-

based special version, the RCE is also clearly the first choice for use in the chemical

industry, the primary industry – here in particular in the manufacturing of fertilisers –

environmental technology and many other areas of industry.

The RCE pumps organic and inorganic as well as aggressive fluids with high solids

fractions during normal and heavy-duty operation and is particularly suitable for

hot media up to 450 degrees.

Examples of use include ammonium nitrate, liquid sulphur, phosphoric acid, tar, pitch,

urea melt, sodium hydroxide solution, water glass, mashes and cataphoretic paints.

MORE THAN 20 MATERIALS

The wide range of materials extends from low-alloy cast steel and high-alloy stainless

steels right through to the purest cast materials such as nickel.

HEATED VERSION FOR ADDITIONAL APPLICATIONS

Areas of application in which the medium needs to be kept at a constant temperature

do not present any problem for the RCE. The use of heating chamber systems

means that the RCE is also ideally suited to difficult situations, e.g. the pumping of

liquid sulphur.

DIFFERENT SHAFT AND STATIONARY SEALING ARRANGEMENTS

Depending on the particular application, the RCE is equipped with different sealing

concepts specially designed to cater to the particular customer‘s requirements.

In addition to all customary mechanical sealing concepts, the use of hydrodynamic

shaft sealing concepts also allows the pump to be used in demanding areas, like

corrosive fluids and/or fluids containing solids.

03

COMPLETELY LEAKAGE-FREE DURING OPERATION

The hydrodynamic shaft sealing variants of the RCE represent a unique and reliable

sealing option. Their area of use extends across special applications in which

standard sealing arrangements such as mechanical sealing systems (mechanical

seals) can no longer operate reliably. This special sealing variant operates without

any contact and without any wearing parts. It does not require any maintenance

and is therefore particularly suitable for continuous operation. Conditions of use

with crystallisation or temperature problems therefore do not present any hurdle

for the RCE.

Impeller back vanes and the additional auxiliary impeller connected downstream

hydrodynamically relieve any pump and feed pressure on the shaft passage in

full. The medium is kept away from the shaft gland and the pump is thus leak-free

during operation. A liquid ring is produced in the area of the auxiliary impeller

which separates the inner area of the pump from the atmosphere without any leaks.

The hydrodynamic shaft sealing arrangement thus only functions fully when the

pump is operating. During stationary periods various configurable stationary seals

insulate the shaft passage off from the atmosphere. Different versions can be

selected for this purpose: The simple stuffing box packing, the pneumatic system

or a ring valve which is mechanically controlled by means of a regulator.

RCE – YOUR ADVANTAGESAT A GLANCE

1 ROBUSTThe special design and the pump

material which is individually custo-

mized for the pumping medium provide

protection from wear and tear.

Special hydraulics make it possible to

pump media with solids fractions of

up to 35 % and increase the efficiency

of the sealing concepts.

The robust bearing pedestal and the

reinforced shaft system guarantee

quiet running with a low amount of

vibration at up to 3500 rpm.

2 DURABLEThe generous dimensioning enables

steady, low-maintenance operation

with constant levels of pumping

performance over many years.

3 FLEXIBLEDepending on the particular application,

pump components made from different

materials can be combined and are

easy to exchange. This means that the

pump can be adapted optimally to

extreme operating conditions.

4 EFFICIENTOptimum flow rates and flow guidance

arrangements are specially designed for

pumping aggressive and abrasive liquids.

This allows a longer life with the best

level of efficiency.

5 INDIVIDUALComplete pump units with all of

the necessary supply components

are tailored to specific customer

requirements. The comprehensive

heating chamber system (RCE DWH)

also surrounds the sealing area.
