Technical Highlights
Discharge Valve Assembly
• Three Concentric discharge valve rings ensure ample gas at flow passage at low lifting height ensuring a smaller number of breakdowns.
• The use of sinusoidal spring made of Sandvik Steel, Sweden together with precision machined and lapped surface result in a trouble -free operation for a remarkable long time.

Cylinder Liner
• Interchangeable cylinder liners are made of fine-grained, centrifugally cast, alloy iron.
• Fine boring and honing results in a mirror smooth running surface.

Crankshaft
• Bearing surfaces of the high-quality nodular cast iron crankshaft are ground to fine tolerances.
Piston
• Perfect sealing and low oil consumption due to 3 compression and 2-oil scrapper rings on each aluminum alloy piston thus minimizing oil carryover through discharge gas line.
Main Bearings
• Main bearings are white metal lined steel backed bushes, pressed into the cast iron bearing covers. Intermediate bearing blocks are provided with spit type bearing shell of the same type.
Connecting Rod Assembly
• The forged steel connecting rod is drilled through for pressure lubrication of the piston pin.
• Steel backed white metal shells on big end and Needle Roller Bearing on small end of connecting rod.

Painting
• With special epoxy primer and Polyurethane (PU) paint preceded by shot blasting and chemical treatment process ensure long life & corrosion protection. Powder coating is optional if demanded.
