Series CMD pumps are designed for long, trouble-free
service life under a wide variety of application conditions with
a minimum of maintenance. The following points will help
provide long service life.
Pumps that are mounted directly to the motor will need to be
removed from the mounting bracket to perform mechanical
seal maintenance or replacement.
CLEANING PUMP: Keep the pump as clean as possible.
This will facilitate inspection, adjustment, and repair work.
STORAGE: If pump is to be stored, or not used for six
months or more, the pump must be drained and a light coat
of light oil must be applied to all internal pump parts.
Apply grease to the pump shaft extension. Viking suggests
rotating pump shaft by hand one complete revolution every
30 days to circulate the oil. Tighten all pump assembly bolts
before putting the pump in service after being stored.
PRESSURE RELIEF VALVES:
Viking pumps are positive displacement pumps and
must be provided with some sort of pressure protection.
This may be an inline pressure relief valve, a torque-
limiting device, or a rupture disk, or other method.
If pump rotation is to be reversed during operation,
pressure protection must be provided on both sides
of the pump.
Pressure relief valves cannot be used to control pump
flow or regulate discharge pressure.
