Double mechanical seals R-4702 is used in drainage and sewage pumps. The double mechanical seal is an analogue of the Burgmann seal and fully corresponds to it in terms of technical characteristics, quality and reliability. This type of seal is used in pumps, compressors, equipment for the food and chemical industries, etc. etc. - that is, wherever it is required to provide high quality sealing of rotating shafts.
High reliability of the operation of the double mechanical seal is ensured by the design of the unit with two seals - primary and secondary. The main lubricant during the operation of the unit is the product itself, with which the equipment works.
The primary double mechanical seal uses friction pairs made of strong and durable materials. The rotating part uses silicon carbide, tungsten carbide, stainless steel. The stationary ring uses graphite, silicon carbide, tungsten carbide.
In the construction of the secondary mechanical seal, various types of rubber resistant to aggressive media are used: NBR, VITON, EPDM, Silicon. Thanks to this, the double mechanical seal reliably resists gasoline, oils and greases, acidic liquids and other chemically active substances.
The main advantages of our double mechanical seals:
Our specialists will be able to select mechanical seals for imported pumps from such companies as Grundfos, KSB, Hilge, Alfa Laval, APV, Wilo, Fristam, Ebara, etc., as well as analogs of mechanical seals AESSEAL, Burgmann, John Crane, Roten, Vulcan. Our catalog contains various types of mechanical seals, which allows you to choose the best option for successfully solving problems in production.
