Hydraulic Seals

Birmingham Seals - Hydraulic seals What are Hydraulic Seals?

Hydraulic Seals are moderately soft non metallic rings, which are used to separate fluid leakage in machinery or in motion appliances. If hydraulic seals are used in the wrong way then they can cause serious problems, but if they are used in the correct way then they are very durable. They are very important components in machinery because of this. Another major failure could be choosing the wrong seal; this could result in huge problems. At Birmingham Seals we supply and offer a variety of hydraulic seals which are available in a range of sizes, materials and styles.

Polyurethane, rubber, plastics, fabric reinforced elastomers and PTFE compounds are all materials which are used in hydraulic seals. Hydraulic seals prevent the leakage of fluid within the cylinder to the outside, where as a piston seal prevents fluid leakage from flowing over the cylinder head. On the rod and piston area of the cylinder they also have two pressure compartments. During the selection of material process you have to consider the different types of temperatures and high pressures that will be applied to the seal when it is inside the machine. These temperature and high pressures will help you decide what type of material and what seal component you will require. A piston seal is a type of hydraulic seal which comes in a selection of styles like the PS1400 and the PS1800. The PS1800 piston ring is a double acting piston, however the Piston PS1400 ring is made from PTFE and rubber.

Common causes of failure in hydraulic seals A common cause of failure of hydraulic seals is the installation of the seals. Installing the wrong type of seal or installing the seal in the incorrect way can cause huge problems for the machine. Another common failure of hydraulic seals is heat erosion.

Because hydraulic seals have different types of resistant temperatures, it is essential that you choose the right seal; if you choose the wrong seal it can be very fatal for you machine. Heat erosion on a hydraulic seal can cause it to melt, resulting in the seal breaking or cracking. Purchasing heat resistant hydraulic seals is one way to prevent heat erosion, ensuring that the seal can still function in the correct way without being damaged by any temperatures. Another common failure of hydraulic seals is chemical erosion. There are various types of hydraulic seals because each of them are more resistant to different types of chemicals, so a way to prevent chemical erosion is to choose the right material of the seal.

Birmingham Seals can help you choose the correct hydraulic seal to satisfy your requirements because they have an extensive knowledge and experience and their vision is to provide high quality seals for you. Birmingham Seals are also able to determine which type, brand and style would be best suitable for your machine. http://www.birminghamseals.co.uk/index.php?webpage=hydraulicseals
