            • 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.

            SEALING SYSTEMS

            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 – for the optimal and safe solution.
              • 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.

                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.

                In the last few years the stationery mechanical seal has established itself in the market, as with this design contaminated and crystallising media can be optimally sealed. Due to a special design solids are kept away from the sealing gap and from the stationary O ring. In addition the working spring is positioned outside the pumped medium.
              • 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.

                The magnetic drive for vertical pumps is different from the horizontal drive in that the drive is not situated in the fluid area, but only seals the gas phase in the container. Here the pump shaft is mounted in grease lubricated anti-friction bearings. Since non-metallic spacer cans are used exclusively there are no eddy current losses, so heat extraction is not necessary.
              • 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. Depending on the application several lip rings can be fitted one behind the other. The spaces in between can then also be provided with a grease lock.

                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.
