Seals KASTAS Seals offered by OOO PTK KRPMS
Engineering and Manufacturing Company OOO PTK KRPMS produces seals for hydraulic cylinders (hydraulic seals). In particular, our company offers the following types of products:
- hydraulic seal,
- pneumatic seal,
- piston hydraulic seals,
- rod seal,
- chevron hydraulic seals,
- rubber O-rings (sealing ring),
- supporting-guiding rings,
- as well as other types of seals.
Hydraulic cylinder seals encapsulate the assemblies during operation, in particular, these are the piston and rod seals. Wiper seals protect the working fluids and the internal parts of the hydraulic cylinder against any extraneous inclusions. Guiding rings reduce the friction coefficient and ensure uniform rod movement.
The use of these components makes it possible to comply with the standards of technological processes and prevent early abrasion of moving parts and components. The types of seals offered by us effectively reduce the contact pressure created by fluid pressure during operation. Due to this, our seals for the piston and other connections feature a longer service life.
Hydraulic seals: sale and manufacture
Kalugaremputmash-Servis company manufactures pneumatic seals at its own production base. We claim the largest production volumes of seals for hydraulic cylinders in the region. Besides, our products are shipped to other regions of Russia and most of the CIS countries.
Hydraulic seals for pistons and rods are made of high quality materials supplied by European manufacturers. They include Seal Maker Produktions-und Vertriebs GmbH from Austria.
Seals: GOST and materials
Each sealing ring in our assortment is manufactured according to the GOST requirements, and all products comply with ISO 9001-2001 certification standards.
Some hydraulic cylinder seals are made of elastomers - high quality rubber. In particular, this applies to a set of seals for fixed joints. We also use polyurethanes to produce seals for hydraulic devices. This material is perfect for hydraulic seals for pistons and other moving parts and assemblies.
Products made of polyurethane, such as hydraulic chevron seals, are more durable and wear-resistant under high loads than rubber seals. Therefore, we are gradually moving towards complete replacement, and our company’s assortment also features polyurethane seals for various types of connections. In assemblies with increased load, a reinforced seal is used, strengthened for compression and effect of increased pressure.
We do not only offer rubber seals for hydraulic devices of our own production, but we are also official representatives of Aston Seals, KASTAS European companies. You can buy from us hydraulic seals of these manufacturers in a wide range for any application and at the most reasonable price.
Seals for hydraulic devices: scope of application
Hydraulic seals produced by us have the widest scope of application. In particular, it includes:
- mechanical engineering,
- chemical industry,
- oil and gas industry,
- metallurgy,
- power engineering,
- food industry,
- woodworking and paper production.
Our rubber and polyurethane seals can be used under various production conditions, including at high or low temperature, as well as at temperature drop, when working with moderately aggressive gases and liquids. This significantly expands the application scope of hydraulic seals presented in our catalogue.
