The RN
Standard chemical pump The standardised chemical pumps RN and RNSi (ferro- silicon cast iron) are used for pumping all kinds of liquids in the wide field of chemical processing, basic chemicals and environmental technology.
Design features
� Design: horizontal, single-stage � Construction: back pull out design according to ISO 2858
� Casing design: single or double volute casing � Bearing lubrication: grease or oil lubrication � Installation versions: Base frame welded or base plate cast
� Ambient temperature: -20 °C to +60 °C � Solid content limit value: approx. 5 % (more with the open impeller)
RN, RNSi
Avoid unplanned downtime
The pump is equipped with the i-ALERT®2 sensor as standard. This monitors vibrations and temperature. If preset limit
values are exceeded, LEDs in the sensor light up. All measured values can be retrieved via an app or the Ai Platform. This means that necessary
measures can be taken in good time before the pump fails.

Many hydraulic sizes (also above and below ISO 2858) allow a size selection with high efficiency and low drive power.
The SIGUSS version RNSi for hot, abrasive, sulphuric acid media ensures increased safety in the plant in the armoured housing.
By using the double jacket, the whole hydrau-lic pump section can be optimally heated by steam, heat transfer oil or electric resistance heating.
The bearing bracket can be equipped with the patented i-Alert® sensor. The i-Alert® sensor enables continuous recording of pump vibrations in three dimensions, as well as the bearing temperature at the bearing bracket. The data can be read out contact-free via Bluetooth.
The wide material range of this series offers the optimum material for every application.
Robust stationary standard mechanical seal All-pac S with FKM coated single spring. The very simply constructed Allpac S has proven itself in many critical applications for decades. The installation spaces according to EN 12756 also allow the flexible use of special seals from all manufacturers. The hydrodynamic shaft seal complements the mechanical seal variants for special applica-tions where mechanical seals cannot be used economically.

Metal materials
High-alloy cast steel 1.4136S / RHRSCorrosion and erosion resistant high alloy ferritic cast steel. Typical applications are highly concentrated sulphuric acid up to 225 °C (437 °F), oleum, fertiliser pro-duction, crude phosphoric acid containing solids.
1.4306SHigh-quality, molybdenum-free material suitable for ap-plications such as pumping of ammonium nitrate melt, hot nitric acid at medium concentrations and also the vaporization of waste nitric acid.
1.4361Low carbon silicon alloy material for pumping strongly oxidising media. Particularly suitable for hot highly con-centrated nitric acid, e.g. 98 % HNO3.
1.4408Fully austenitic chromium nickel molybdenum steels with a good general resistance to corrosion. These materials are suitable for pumping almost all organic liquids, 50 % caustic soda up to 90 °C (194 °F), KTL paint, pure phos-phoric acid, dry chlorine, liquid sulphur, PTA and many other media.
1.4463Semi-austenitic, easily welded material with an increased strength and good general resistance to corrosion. Due to its good welding properties and wear resistance it is frequently used for jacketed pumps for handling melts containing solids, such as pitch and tar.
The range of metallic materials includes a wide range of very different types of material which are distinguished mainly by their alloy composition, their structure and their manufacturing process. This gives each material its characteristic properties and allows an optimal material to be selected to suit the application.
1.4517Duplex (Semi-austenitic), molybdenum and copper al-loyed material with a high resistance to pitting and stress corrosion. This material is one of the super duplex steels. lt can be used with crude phosphoric acid, containing solids at up to 100 °C (212 °F), hot sea water, many solu-tions containing chloride, FGD suspensions and sulphuric acid at all concentrations at low temperatures.
1.4529SA high grade special material having a high resistance to acidic media containing solids and rich in chlorides. Used in absorber and quencher fluids of the FGD, for acidic and chloride containing gypsum slurries, in the manufacture of phosphoric acid, in vaporisation and crystallisation processes and also for hot sea water.
1.4652SHigher austenitic cast material with very high corrosion resistance. Especially in very corrosive phosphoric acid with solids this material is perfectly suitable.
R 3020 Fully austenitic special stainless steel with a high molyb-denum and copper content. High resistance to pitting, stress corrosion and intercrystalline corrosion. Suitable for 70 % caustic soda up to 200 °C (392 °F), sulphuric acid at all concentrations at low and medium tempera-tures, sulphuric acid pickling solutions, in certain areas of the manufacture of phosphoric acid, for pumping solutions with a high chloride content and in spin baths.

Pure metals
3.7031 Titanium is especially resistant to heavily oxidising and chloride containing media. The material is preferred for use in chloralkali-electrolysis, bleaching solutions con-taining chlorine and in the manufacture of acetic acid.
3.7032 Titanium alloyed with palladium. This improves the cor-rosion resistance in reducing media, e.g. in solutions of iron chloride or aluminium chloride containing hydro-chloric acid.
Nickel based materials
2.4686 Highly resistant nickel-base alloys for special applications such as liquids containing high chloride, hydrochloric acid, FGD liquids, very heavily contaminated phosphoric acid, hypochlorites and solutions with oxidising chlorides.
Silicon iron alloys
SIGUSS Highly corrosion resistant chromium alloy silicon cast iron with a good resistance to wear and increased chemical resistance. This material is chemically resistant to H2SO4 at all concentrations up to boiling point, therefore for all sulphuric acid applications including the evaporation of waste sulphuric acid, SIGUSS is virtually indispensable.

SealingsDepending on the application, a selection can be made between hydrodynamic seal or mechanical seal variants.
Design CS Internal, balanced mechanical shaft seal type Allpac S by Rheinhütte with stationary spring-loaded face and rotat-ing face
Design CST Double mechanical seal with stationary seal ring and downstream standardised mechanical seal with feed thread
Design CN1 Single acting standardized mechanical seal � internal or external circu-lation
� Quench connection easily retrofittable as an option
Design CN2 Double acting standardized mechanical seal in „back to back“ arrangement
Design CT Two internal mechanical seals, which are arranged in tandem configuration.
Design B Hydrodynamic shaft seal. If necessary, there is the possi-bility of a barrier or a flushing medium. (See picture on page 9)
Design DCA Hydrodynamic seal and addi-tional standstill sealing con-trolled by centrifugal force � Liquid repellent PTFE bel-lows with generous cavities
