3.3. Piston pumps for progressive
distributor systems
Piston pumps for progressive distributor systems
differ from piston pumps for piston distributor
systems in that they do not have a pressure relief
valve. In these piston pumps, the lubricant drawn
from a separate or attached lubricant reservoir is
fed to the progressive distributors via the pressure
regulating valve in the piston pump. The progressive
distributors in turn distribute the lubricant to the
individual lubrication points.
Piston pumps for progressive distributor systems
can be actuated several times in sequence if the
lubricant quantity of a piston stroke is not sufficient
to fill the entire centralized lubrication system.
