Cylinder and Packing Lubrication
Independent Force Feed Lubricator Systems
The cylinders and packing require an oil supply with a viscosity below 5000 SUS (1100 cSt)
at the lubricator pump inlet. Measures which may be necessary to make sure that the force
feed pump is filled with oil during the suction stroke include; appropriate pipe and fitting size
from the tank to the force feed pump, heating the oil, and pressurizing the supply tank.
Common Oil Supply
When process gas composition and cylinder operating conditions allow compressor frame
lubricating oil to be used for cylinder and packing lubrication, the resulting force feed lube
systems are installed as shown in Figure 4-5.
