Reciprocating Gas Compressors
The
single stage, reciprocating compressors create a low-pressure area in the
pumping chamber when the piston moves
from the highest point of the stroke to the lowest point. Gaseous product
(at a higher pressure in the tank) moves into the pumping chamber.
This volume of gas is then displaced when the piston moves to the top
of the
stroke. Equipped with high efficiency valves, ductile iron pistons,
self-adjusting piston rod seals and other robust features, these compressors
are designed
to provide maximum performance and reliability under the most severe
service conditions.

High efficiency, PEEK valves
Blackmer valves are specifically designed for oil-free gas applications. Standard
valve plates are constructed of self-lubricating PEEK (Poly Ether Ether Ketone)
material that provides superior sealing characteristics, high efficiency
and durability. Optional stainless steel Hoerbiger valves are also available.
Note: Series HD160 and HD170 have TNT-12 impregnated steel valves
Live loaded piston rod seals
Filled PTFE seals are wear compensating and maintain a constant sealing pressure
around the piston rods with minimum friction. This special seal design prevents
crankcase oil contamination and cylinder blow-by.
Single or doubledistance piece
Single or double distance pieces (isolation chambers), control contamination
of the compressed gas from crankcase lubricant, even at high vacuum inlet conditions.
Each isolation chamber may be independently purged, pressurized or vented for
maximum containment of toxic or hazardous gases.
Heavy-duty precision ground crankshaft
The ductile iron crankshaft features roller bearings and integral counterweights
for smooth, quiet operation. Rifle drilling ensures positive oil distribution
to the wrist pin and connecting rod bearings.
Self-lubricating piston
rings
Extra-thick, self-lubricating filled PTFE piston rings provide more wear surface
for maximum sealing and extended life.
Ductile iron construction
All pressure parts are ductile iron for greater resistance to both thermal and
mechanical shock. For extended wear and corrosion resistance, specify the TNT-12
PTFE and Nickel impregnation option.
O-Ring seals
The head and cylinder are sealed with O-rings to ensure positive sealing under
severe operating conditions. Buna-N, FKM, Neoprene, PTFE or Ethylene- Propylene
O-rings are available.
One piece piston
Heavy-duty steel pistons are connected to the rod with a single positive locking
nut, which eliminates potential problems associated with multiple piece designs.
Pressure lubricated crankcase
A self-reversing oil pump provides positive oil distribution to all running gear
components for long life and minimal wear. A full-flow spin-on oil filter is
standard.
ANSI flanges
Many models are available with
ANSI flanges for compatibility with CPI and refinery industry standards.
