General Information
Compressors are extremely versatile for they can be used to transfer liquids
between tanks, off-load/load out liquids, recover residual vapor, and evacuate
vapors for maintenance purposes. Many LPG piping systems do not provide
ideal NPSH conditions for liquid pumps which causes excessive pump
maintenance. Since compressors are only exposed to vapors, they are not
affected by poor NPSH conditions. Many LPG pressurized tanks such as
railcars and buried tanks have top unloading connections. A compressor can
be the perfect solution for transferring liquids to and from such tanks. 
  Features

• High efficiency valves move more gas volume
  The heart of any compressor is its valve assembly and our valves are 
  specifically designed for non-lubricated gas applications. With precisely
  engineered clearances, spring tension, and a special finish, these valves
  seat more positively so more gas is moved with each piston stroke.
  Our valves offer greater strength, quiet operation, and long life.
• O-Ring seals-head and cylinder
  The head and cylinder are sealed with O-rings to ensure positive sealing under
  all operating conditions.
• Pressure assisted piston rings for positive seating
  Constructed of self-lubricating PTFE, Blackmer's special ring design provides
  maximum sealing efficiency with minimal friction wear. The result: peak
  performance and extended compressor service life.
• Heavy-duty crankshaft
  The ductile iron crankshaft is precision ground with integral counterweights for
  smooth, quiet operation. Rifle drilling ensures positive oil distribution to the
  wrist pin and connecting rod bearings.
• Pressure lubricated crankcase
  A rotary oil pump provides positive oil distribution to all running gear
  components for long life and minimal wear.
• Wear-resistant crosshead assemblies
  Designed for maximum lubrication and wear resistance.
• Ductile iron pistons
  Heavy-duty ductile iron pistons are connected with a single positive locking nut
  which eliminates potential problems associated with more complex designs.
• Self-adjusting piston rod seals
  Crankcase oil contamination and cylinder blow-by is prevented with loaded
  glass-filled PTFE seals which maintain a constant sealing pressure around
  the piston rods.
• Ductile iron construction
  All pressure parts are of ductile iron for greater resistance to both thermal
  and mechanical shock.
