Spare parts for reciprocating compressors

Piston and guide rings

STASSKOL rings are applied:

• for any technical gas
• for bone dry gases
• for Oxygen, including BAM-certificate
• up to 700 bar final pressure
• for lube and non lube service
• PEEK materials, PTFE-Compounds
• for any design:
• rectangular rings with/without springs
• angular rings
• labyrinth type ring
• one piece and multiple piece design rings

Piston rod packings

Piston rod packings for lubricated or non-lubricated piston compressors (cooled and non-cooled version with connections for leakage gas, buffer gas, purge gas and with static pack)

Intermediate packings

Instead of pressurizing the crank case, is necessary to fit a double distance piece, which is separated from each other by the use of an intermediate packing.

Intermediate packings are applied especially when it comes to the compression of toxic and highly combustible gases. Since these packings are purged they contribute to the safety of the plant.

Oil wiper packings

Material that used for oil wiper rings:

• White bronze
• Grey cast iron
• Bronze
• White metal
• PTFE

Valve series

Valves are used for controlling the air, oil and refrigerant circuits in compressors. They function mechanically and open and close at defined pressures.
In case a valve functions incorrectly or does not function at all, this can lead to contamination of the connected system and end product, overheating as well as an unforeseen failure of the compressor.
