Power Plant
No power station can be operated without mechanical seals. The number of sealing locations to be controlled is correspondingly large. So, there are quite a number of plant components that need to be sealed: rotating equipment, such as pumps, agitators, coal mills and compressors; valves, flanges and pipes and ducts carrying gases and liquids. The reliability of the entire power plant depends on a number of individual parts. The seals, as key components, play an important role. They protect the media in the process from external influences and help prevent emissions. They enhance process reliability, availability and economic viability of the power plant.
Power Plant
Sealing systems featuring maximum operational reliability, convenient maintenance and low leakage rates with necessary environmental protective measures are standard requirements in modern power stations. The product range includes mechanical seals and supply systems for auxiliary and secondary pumps, boiler circulation pumps and feedwater pumps as well as mechanical seals and carbon floating ring seals for turbines, compressors and fans.
Sugar Industry
Sugar factories have numerous pieces of rotating equipment requiring sealing. With the ever-increasing demands for improved efficiency, reduced waste and effluent and improved equipment reliability, there is now an industry shift from traditional sealing methods.The use of modern high-quality cartridge mechanical seals and associated support systems is now becoming the industry norm. These seals guarantee plant uptime and significantly reduce water wastage and the resultant effluent.Based on experience gained over the past 10 years in the sugar and syrup Industries, Rota-Tech has successfully sealed most applications in the modern sugar mill.
Sugar Industry
Sugar campaigns are over in a relatively short time. For optimum economy and ecological it is all the more important, therefore to have a reliable sealing system. In the past it was normal for juice pumps to be equipped with double seals to cope with the tendency to crystallization and carbonation. Today the use of single mechanical seals is possible in most of the cases due to availability of modern materials and new seal compartment geometries.
Petrochemical & Chemical
Rota-Tech mechanical seal can use in the petrochemical industries.Rota-Tech company also has the certain knowledge about mechanical seals for petrochemical industry, and the mechanical seal products are also widely used in the petroleum industry.In petrochemical industry, the transport medium of rotating equipment is usually high temperature, high pressure, flammable, explosive, toxic and harmful fluid, and its reliability is particularly important. Mechanical seal has been widely used because of the advantages, such as high reliability, good interchangeability, simple structure and compact structure, convenient maintenance and so on. We need to analyse the seal structure, material and flushing, and choose the suitable petrochemical mechanical seal for the pump, so as to improve the reliability of the seal. In petroleum industry, double face mechanical seal is a good choice.
Petrochemical & Chemical
In this Industry chemically inert materials are often used for the mechanical seals produced and, depending on the specific sector's use, alumina, PTFE, Kalrezor FEP can be used. In this way, Rota-Tech answers all the productive standards that underlie the production of mechanical seals for the chemical sector in complete conformity of the regulations in force.
RUBBER & TYRE INDUSTR
Mechanical Seals are used extensively within the Rubber Industry for both mixing and extrusion. There are different types of machines which will use Mechanical Seals within the Rubber Industry, such as; Mills, Calendars and Extruders (which make profiles). The machine that is normally used is the Banbury Mixer. The rolls are heated and cooled to keep the product at a certain temperature. Rubber Extrusion is similar to Plastic Extrusion. The Extruder pushes material through a barrel with a screw. The Extruder is a machine which applies shear force to a raw product (such as rubber) to make it into a final product.
RUBBER & TYRE INDUSTR
The materials used in the Rubber and Tyre industry need to be capable of coping with the large array of media, many of them explosive or toxic and others which could become when mixed. An increased awareness of environmental risks calls for a maximum reliability and operational safety, especially from sealing systems. Against this background, the sealing systems used in applications involving what are in many cases explosive, toxic or aggressive media have to ensure optimum tightness.
PULP & PAPER INDUSTRY
Rota-Tech has introduced a range of innovative, patented mechanical seal products to meet the vast range of demands of the pulp and paper and paper-recycling industries.We aim to design and manufacture products that exceed expectations for reliability and performance:Exotic alloy technology for chemical and bleaching millsAxial movement seals for refining equipmentPatented Seal Support System solutions for hot or arduous applications, including condensate and digester liquor.Rota-Tech has proven expertise in all pulp and paper production processes.
PULP & PAPER INDUSTRY
In paper sector high temperature mechanical seals like metal bellow mechanical seals are used to flow media fromthese stationary pipes to rotating rolls without any leakage.Rolls which used to dry the wet paper, must be heated. To heat these rolls; hot oil or steam is used. While rolls rotate, supply and return lines are stationary.
IRON & STEEL INDUSTRY
Metal processing is the extraction of metals from their ores, modification of metals for use and combination of metals to produce specific alloys.It is often a highly arduous process, including the blast furnace, smelting and necessary condensate applications.Rota-Tech has a range of sealing technologies to increase reliability for all stages of metal processing.
IRON & STEEL INDUSTRY
In Iron and Steel industry casting process of hot steel is cooled with rolls. These rolls are cooled with water. While hot steel passes, these rolls rotate and Mechanical seals are used to transfer water to stationary supply lines to rotating rolls. In addition, withdrawal and straightening units are cooled with water by using mechanical sealsmounted in pumps.
OIL & GAS INDUSTRY
The extreme demands placed on equipment within the Oil and Gas industry require high standards of reliability, operational best practice and leading-edge technical expertise.

With the continuous exploitation of marine resources, the use of underwater equipment is becoming more and more diversified. Among them, the seal design is to ensure the normal use of underwater equipment, is the key link about the safety and reliability. Therefore, the excellent marine seal design is necessary. We can discuss the shipping seals as an example. Mechanical seals are gradually applied to the stern shaft seal of ships with the advantages of less leakage, good sealing performance, and durability, and become an important part of ship propulsion system.Mechanical seals are applicable to the caudal tube of the ship. In addition, it is also used for hydropower and wind power.
Marine Industry
With automation in marine applications and the protection of our seas, the sealing technology is becoming increasingly important. Various different media need to be sealed in the tightest of spaces on board ships: the spectrum of applications in this sphere ranges from fuel supply, fire-fighting facilities, bilge and ballast tank pumps right through to tubular stern seals, thru-bulkhead receptacles and flue gas ducts. Many of the seals used in such applications have to be seawater resistant, so in many cases are made from high-quality materials.
