Types of Piston Seals

There are different types of piston seals available, each with its unique properties and advantages. The most common types of piston seals are:

Single-acting piston seals: These seals are designed to prevent fluid leakage in one direction only. They are commonly used in applications where pressure is applied to one side of the piston only.
Double-acting piston seals: These seals are designed to prevent fluid leakage in both directions. They are commonly used in applications where pressure is applied to both sides of the piston.
Composite piston seals: These seals are made of a combination of materials, such as PTFE and elastomers. They are designed to provide high levels of wear resistance and durability.
SPGO piston seals: These seals are low-friction piston seals that combine PTFE and bronze seal rings. They are designed to provide a perfect combination of sealing performance and service life by optimizing contact pressure and reducing the heat generated by friction.

In conclusion, piston seals are an essential component of hydraulic and pneumatic systems. They are designed to prevent fluid leakage, maintain pressure, and ensure efficient operation of the system. There are different types of piston seals available, each with its unique properties and advantages. Choosing the right type of piston seal depends on the specific application and operating conditions.

SPGO Seal Design

Material Composition

SPGO seals are made of a combination of materials that provide excellent performance in hydraulic systems. The seal ring is made of PTFE (polytetrafluoroethylene) filled with bronze, which provides good wear resistance and low friction. The rubber energizer O-ring is made of NBR (nitrile butadiene rubber), which provides good sealing performance and resistance to hydraulic fluids.

The combination of the PTFE and bronze materials provides excellent resistance to high temperatures and chemical corrosion. This makes SPGO seals ideal for use in hydraulic systems that operate under high pressure and temperature conditions. The NBR rubber energizer O-ring provides a good seal against hydraulic fluids, preventing leaks and ensuring system efficiency.

Profile Characteristics

The SPGO seal has a D-shaped profile, which provides a good balance between sealing performance and low friction. The seal is designed to fit into a simple groove, making it easy to install and maintain. The seal ring is energized by the rubber O-ring, which ensures that the seal maintains its shape and provides a good seal against hydraulic fluids.

The SPGO seal is suitable for use in both uni-directional and bi-directional piston sealing scenarios. It is highly effective in heavy-duty applications where high pressure, low pressure, and high-frequency conditions are present. The seal provides excellent sealing performance, reducing the risk of leaks and ensuring the efficient operation of hydraulic systems.

In summary, the SPGO seal is a highly effective piston seal that provides excellent sealing performance and low friction. Its combination of materials and profile characteristics make it ideal for use in hydraulic systems that operate under high pressure and temperature conditions.

Installation of SPGO Seals

Pre-installation Procedures

Before installing SPGO seals, it is important to ensure that the piston rod is clean and free from any damage. Any dirt or debris on the rod can damage the seal and reduce its effectiveness. It is recommended to clean the rod with a lint-free cloth and a suitable cleaning agent.

Additionally, you should check the dimensions of the seal and the groove to ensure that they match. Any mismatch can cause the seal to fail prematurely or leak. You can refer to the manufacturer's specifications or use a caliper to measure the dimensions.

Installation Techniques

There are several techniques that you can use to install SPGO seals. Here are some of the most common ones:

Press-fit installation: This involves pressing the seal into the groove with a suitable tool. You should ensure that the seal is aligned properly and that it is not twisted or damaged during the installation process.
Heat installation: This involves heating the seal to make it more pliable and easier to install. You can use a heat gun or an oven to heat the seal. Once heated, you should quickly install the seal into the groove and allow it to cool down.
Lubrication installation: This involves lubricating the seal and the groove with a suitable lubricant before installation. This can help to reduce friction and make the installation process easier. You should ensure that the lubricant is compatible with the seal and does not cause any damage.

Regardless of the technique you use, you should ensure that the seal is installed properly and that it is not damaged during the process. You can refer to the manufacturer's instructions or seek the advice of a qualified technician if you are unsure about the installation process.
