      • CPDR - Standardized chemical pump in plastic

      • Pumps of the CPDR and CPRF type family are horizontal, single-stage, end-suction, top-discharge centrifugal pumps, standardized to EN 22858 (formerly DIN 24256; ISO 2858 and ISO 5199). The installation length of type CPRF is simply longer about the channel width so that a free passage for the fluid is given. The pumps are used for handling chemically aggressive and/or inflammable liquids within the wide field of chemical processing and environmental technology. The CPDR with open impeller is foreseen for clean liquids and fluids with a small content of solids. The CPRF is able to handle fluids with larger solids. Both types are possible in close-coupled design instead of bearing block.

        Applications:

        Chemically aggressive, even contaminated, media throughout the whole range of chemical processing technology, surface coating technology, environ-mental engineering and other areas of industry.

        • RHEINHÜTTE Pumps in metals

        • The range of metallic materials encom-passes a wide variety 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.
        • RHEINHÜTTE Pumps in plastics

        • In pump engineering the non-metallic materials which are mainly used, are predominantly fluoropolymers and polyolefins. The advantage of these materials is their high resistance to acids and alkalis at low to medium temperatures. To resist external forces these pump types are usually protected by a metal casing.
        • RHEINHÜTTE Pumps in ceramics

        • Pumps made of ceramic materials are particularly suitable for media which are highly abrasive and at the same time corrosive, where pumps made from metallic materials and plastics may have a relatively short operational life.

          • FRIKORUND®
      • Sealings

      • SEALING SYSTEMS
        perfectly matched

        If the plant is to work safely and economically the pump design and sealing system must be perfectly matched with each other. A wide variety of seal variants is available when designing pumps:
          • Hydrodynamic sealing

          • The hydro-dynamic shaft seal works without contact and without wearing parts. It requires no maintenance of any sort and is particularly suitable for continuous operation. With the aid of impeller back blades and a downstream auxiliary propeller the shaft gland is completely relieved hydro-dynamically from the pump and inlet pressure. The medium is kept away from the shaft gland.

            When the pump is operating a liquid ring appears in the auxiliary impeller which isolates the inner pump chamber from the atmosphere without any leakage. The hydro-dynamic shaft seal thus only functions fully during operation of the pump. After switching off the pump a stationary seal takes over the task of sealing the shaft gland from the outside. For this a choice can be made between a simple packing gland, a pneumatic system or even a mechanically controlled ring valve of various designs.

            The hydro-dynamic shaft seal, with few exceptions, is suitable for all pure or solids bearing media which occur in the chemical industry, based materials industry, environmental technology etc.
          • Mechanical seal

          • Single or double acting mechanical seals are used to seal the shaft gland. Sealing is achieved through axial sliding faces which are pressed against each other by spring force and this prevents them opening when at rest. The stationary part of the mechanical seal usually sits in a housing and the rotating unit on the shaft sleeve. In the sealing gap between the sliding faces a lubricating film is generated by the pumped medium in order to prevent the sliding faces running dry.

            Allpac S
            The standard mechanical seal Allpac S can be used universally, even with abrasive media, and is also characterised by its ease of maintenance due to the small number of components. With the double acting mechanical seal two seals are arranged one behind the other so that an additional space occurs between the sliding face of the seals which in turn can be supplied with a pressurised external sealing medium. This ensures that no product can escape into the atmosphere.

            RHETA
            RHETA - designed by RHEINHÜTTE and EASY TO ASSEMBLE. The metal-free mechanical seal is characterized by its high service friendliness. Disassembly is quick and easy from one side. Changing from CS to CST is also uncomplicated and quick. In contrast to conventional mechanical seals, RHETA consists of innovative materials that ensure a long service life. The seal is completely metal-free so that components cannot corrode. Both the housing and the sealing cover are made of durable plastic, which can handle high temperatures of up to 130°C without any problems. RHETA also offers the advantage of integrated service flushing so that occasional flushing can be performed easily and cost-effectively.
          • Magnetic coupling

          • The magnetic coupling is based on a completely different sealing principle. Here the drive for the hydraulic part of the pump takes place through the pairing of permanent magnets whose external unit transmits the torque generated by the motor to an internal unit, which in turn transfers this to the impeller.

            The external or atmosphere side magnet system is separated from the internal product side magnetic system by a spacer can made of non-magnetic material. The torque needed to drive the impeller is transmitted exclusively by magnetic forces which act through the spacer can. The pump it is thus hermetically sealed.

            The axial and radial mountings for the pump shaft are through hydro-dynamic sleeve bearings made of silicon-free silicon carbide. Bearing lubrication and heat removal normally takes place through the pumped medium, in two separate circuits.
          • Stuffing box packing

          • For a long time the packing gland was the standard in plant technology. It still proves its validity today in special applications.

            A packing gland must continually exhibit a minimal leakage. This leakage serves to cool and lubricate the packing string. At the optimal setting of the packing gland the is a minimal leakage of 20 to 40 drops per minute. This figure however is heavily dependent on the pressure, the sliding speed, the medium and the temperature.

            Often a lantern ring with two connections is fitted in order to dilute and discharge the product leakages. Different materials and combinations are used depending on the application.
          • Lip ring seal

          • This type of shaft seal is used mainly on vertical pumps, to protect the anti-friction bearings from water splashes. Different lip rings made of different materials can be used.

            So for example a friction optimised shaft seals are used, and also pretensioned PTFE lips, which rotate on hardened shaft sleeves. For horizontal pumps the quench chambers are usually sealed by single acting mechanical seals with a lip ring. This sealing principle is also applied as stationary sealing for hydrodynamic shaft seals.
          • Labyrinth seal

          • This type of shaft sealing is used mainly in vertical pumps in order to protect the anti-friction bearings from water splashes. Different lip rings made of various materials can be used. Thus for example friction optimised shaft seals are used and also pretensioned PTFE lips which then rotate on hardened shaft sleeves. Depending on the application several lip rings can also be fitted one behind the other.

            The intermediate spaces can then also be furnished with a grease lock. ith horizontal pumps the quench chambers are usually sealed by single acting mechanical seals with a lip ring. This sealing principle is also put to use as a station which seal for hydro-dynamic shaft seals.
