Pu Seals

Pu Hydraulic Seal :

Now a days, Pu Hydraulic Seals are widely used in Hydraulic cylinders in different industries. Pu Seal controls the flow of hydraulic fluid to generate a reciprocating motion. Most of the hydraulic seals are polyurethane(PU) seals. Hydraulic PU seals have better abrasion and tear resistance than rubbers, and offering higher load-bearing capacity. Besides Polyurethane can reduce factory maintenance and OEM product cost.

Hydraulic Seal Material :

Hydraulic seals can be made from different types variety of materials such as polyurethanerubber or PTFE. We can evaluate type of material by fluid type, pressure and temperature.

Types of PU Hydraulic Seals :

Mainly there are 4 types of hydraulic seal-

1. U-Seal (Piston-Rod Seal)

Rod & Piston seals are equal lip-seal act like both piston seals and rod seals. They are also the most critical seals on any type of fluid power equipment. Moreover, it prevents leakage of fluid from within the cylinder to the outside.

2. Rod Seal

Rod seals ensure that fluid does not leak from the cylinder and maintains adequate pressure. That is why, the rod seal is the most critical seal on any type of fluid power equipment. It prevents leakage of fluid from within the cylinder to the outside.Rod seals must meet the most demanding requirements. Leakage through the rod seal can reduce equipment performance, and also in extreme cases can cause environmental issues. Therefore it is important to choose the correct rod seal type and design for a particular application.

3. Piston Seal

Hydraulic Piston seals prevent fluid from crossing the area of the piston head. Piston seal is exposed to movement on its outer diameter along the tube or bore of a hydraulic cylinder. But, Different Piston Seal profiles offer distinct advantages depending on the sealing application.

4. Dust Wiper Seal

Wiper seals prevents contamination from entering the hydraulic system.

Advantage of PU Seals :

1. Particularly strong wear resistance.
2. Insensitivity to shock loads and pressure peaks.
3. High crush resistance.
4. It has an ideal sealing effect under no load and low-temperature conditions.
5. Suitable for demanding working conditions.
6. Easy to install.
