Reciprocating Compressor

May 8, 2013

Blackmer HD Gas CompressorAvailable in either single- or two-stage configurations, Blackmer's HD and HDS Series Oil-Free Reciprocating Gas Compressors have been designed for maximum performance and reliability under the most severe operating conditions. They are equipped with high-efficiency ductile-iron valves with PEEK valve plates, ductile-iron head and cylinders, two sets of self-adjusting filled PTFE packing sets on each piston rod for maximum leakage control, self-lubricating TFE piston rings, a precision-ground crankshaft and a pressure-lubricated crankcase. The non-lubricated design means no lubricating oil is used in the upper cylinder or head area where it could add additional contaminants to the gas stream. HDS model compressors are built for sour gas applications using special NACE-compliant materials for exposure up to 8% by volume of H2S.
