Malfunction
− Pump does not operate
− Pump operates, but does
not supply lubricant
−

lubrication points
−
No grease collar at several
lubrication points
− No grease collar at one
lubrication point
−
Reduced pump speed
Cause
− Fuse of unit blown
− Integrated electronic
control defective
− Electrical cable broken
− Pump defective
− Pump element not nested
− Air in the feed piston
− Filling level below
minimum
− Defective pump element
− Pump does not operate
−
Cycle time too long
− Lubrication time too short
− Number of strokes too low
− Number of rotation too low
− Pump element PE-120 V
adjusted too low
− System blocked
− Feed pipes for secondary
distributors burst or leaky
− Fitting leaky
− Appropriate lubrication line
burst or leaky
− Fitting leaky
− High pressure in the
system
