Piston rings

Main functions of compression rings

 Piston rings, mounted on the pistons of lubricated or non-lube (oil free) compressors, are designed to ensure that the gas is compressed and to provide a seal between the piston and the cylinder.

The piston ring is an essential part of a reciprocating compressor, as it enables the requested or required performance in terms of flow rates and pressures to be achieved.

High-performance piston rings :

• Manufactures its piston rings in a wide range of extremely wear-resistant materials.

• Also offers a wide range of designs for improving the sealing function according to the pressure, molecular weight of the gases (especially in the case of low density gases) and the materials used.
