Revamp / Innovation on Reciprocating Comp’
● Hydraulic Fit connections at piston rods on both sides.
● Free Floating Piston technology to increase lifetime of wearing piston parts.
● Conditioning Monitoring to minimise maintenance intervals.
● New Compressor Parts to the latest technology and in case of process parameter changes.

Frame – Main Bolt Connection
Main bolt connections- If studs on the main connections are corroded or higher loads to the compressor parts are applicable due to new process
conditions we recommend to changed them out for studs with Rolled thread - Rolled thread increases the fatigue strength 1.5 to 2 times.

CylinderFree Floating Piston
- practically no rider ring wear- increased reliability and availability- increased lifetime of piston rings and stuffing box elements - no lube oil pollution of process and valves- no cylinder lubrication system, no lubrication costs- reduced preventive maintenance costs (time and materials)- reduced production losses
Gas flow true-out the piston via nozzles in the rider rings
Gas flow through FFP Process gas flow

Process change
New liner and piston diameter - To optimize the cylinder performance in case of a process change, provide
new liner and piston with other diameters. - These new designed parts can be
installed in the original cylinder
