Continuation of "KFG/KFGS pump malfunctions" table

Fault

Category

Possible cause

Rectification

Pump does not
deliver any lubricant,
although agitator is
rotating.

Malfunction



Suction problems due to air pockets

in grease



Pump element does not build up pressure,

pump element is worn out.
(This is indicated when the outlet can be
closed with a finger once the main line is
removed.)



Lubricant too stiff

• Dismantle pump element and operate pump using the

key until grease discharges from outlet on housing.

• Replace pump element

Note:

metering is indicated by grooves.

• If necessary, adjust lubricant to work properly at lowest

working temperature.

Pressure regulating
valve on pump
opens and lubricant
discharges.

Malfunction



System pressure is over 200/300 bar, e.g.,

due to feeder blockage or blocked lubrication
point.



Valve is damaged or contaminated, so it does

not close properly.

• Check system and repair/rework the system so the

maximum system pressure at 20 °C is 200 bar.

• Replace pressure regulating valve .
