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.
