Single line-resistance (oil only)
Operation: ii motor driven piston pump discharges a
predetermined volume of oil at controlled intervals to a
single main line. Flow units in, the system proportion the
total pump discharge according to the relative resistance
of the units.
Care needs to be taken in the selection of components to
ensure each bearing receives the required volume of
lubricant; as a result, this type of system is used predomi-
nantly for original equipment application.

Applications: Machine tools and textile machinery
Specification:

Outlets: 1-100 (0.01-1 ml)
Pressure: 300-500 kN/rn2
Lubricants: 10-1800 cSt (Oil only)
Failure warning: line pressure monitoring.
Cost factor: Low.
