The robust RCE chemical centrifugal pump: Flexible solutions for extremely demanding media

Wiesbaden, June 2015. The RCE chemical centrifugal pump from FRIATEC

AG - Division Rheinhütte Pumpen offers a reliable and durable solution for

varied and difficult pumping tasks in many areas of industry.

The optimum pump is selected for a specific project from more than 35 sizes

with different sealing variants and optional heating systems. With a

hydrodynamic shaft sealing system, this design ensures that maintenance-free

and wear-resistant pumping of extremely demanding fluids is achieved. A

broad range of corrosion-resistant materials enables the use of the RCE for

specific applications. More than 20 materials are available, ranging from low-

alloy materials (cast steel) and high-alloy stainless steels to the purest of metals.

The RCE covers flow rates of up to 1,300 m³/h and differential heads of up to

180 m.

Individual solutions for sophisticated pumping tasks

The RCE chemical centrifugal pump is ideal for pumping chemically aggressive,

hot and contaminated fluids. This robust design can pump inorganic, organic

and aggressive media with temperatures of up to 450 °C, including media

containing solids, under normal and difficult operating conditions. It is primarily

used to pump liquid sulphur, phosphoric acid, tar, pitch, molten urea, lye,

ammonium nitrate, liquid glass, mash and cataphoretic paint.

The RCE chemical centrifugal pump impresses through its reliability and a safe

and, simultaneously, robust and durable design with a variety of sealing

variants. The horizontal RCE series has proven itself for decades in the

chemical industry and also the raw materials industry where it is primarily used

in fertiliser production. It is also the first choice in environmental engineering and

many other industrial areas.

Maximum safety with sealing concepts for specific applications

The RCE chemical centrifugal pump is adapted to individual pumping tasks

through sealing concepts developed for specific applications. In addition to the

mechanical seal option, the hydrodynamic shaft sealing system makes it ideal

for pumping particularly demanding media which, for example, have a strong

tendency to stick together or crystallise. This maintenance-free sealing variant

functions contact-free, has no wear parts and seals the pump completely

against leaks during operation. A liquid ring seal configures itself in the auxiliary

impeller while the pump is operating, separating the interior of the pump from

the atmosphere and preventing leaks. Following deactivation of the pump, a

stationary sealing system takes over this function, sealing the shaft passage to

the outside. A simple stuffing box packing, a pneumatic system or a

mechanically controlled ring valve can be selected, depending on the application

involved. The hydrodynamic shaft sealing system is mainly suitable for use in

continuous operation.

Heated design for constant temperatures

The RCE chemical pump with heating chamber systems (H design) can be

adapted for pumping tasks in which the medium must be maintained at a

constant temperature. The casing drain system, drain and stuffing box chamber

of this pump are completely heated. This permits use of the RCE for particularly

demanding applications such as pumping molten sulphur. It has the advantage

of ensuring that no sulphur residue solidifies and forms deposits in the shaft seal

chamber during pump start-up and shutdown.

The project determines the solution

Rheinhütte Pumpen has been realising molten sulphur pumping projects for

more than 60 years, and these years of experience form the basis when

realising specific customer application solutions in modern sulphur plants.

Rheinhütte Pumpen experts provide support with regard to design, material

selection and sealing systems as early as the planning phase.

The project consulting service provided by Rheinhütte Pumpen offers particular

advantages in difficult pumping tasks such as the use of loading pumps for

molten sulphur. Continuous switching on and off subjects sealing systems in

loading pumps to particularly high levels of stress. Rheinhütte Pumpen selects

the optimum sealing system in close consultation with plant operators to ensure

long operational lives and maximum degrees of reliability during operation.
