CUTAWAY VIEW MAG DRIVE PUMP, MODEL LS-825 MD-D B ILLUSTRATED
Series 825, 823, 827 pumps are designed for long, trouble-free
service life under a wide variety of application conditions with
a minimum of maintenance. The points listed below will help
provide long service life.
CLEANING UNIT: Keep the pump, coupling and motor as
clean as possible. This will facilitate inspection, adjustment,
and repair work.
STORAGE: If the pump or coupling are to be stored, drain
the pump and pour non-detergent SAE 30 weight oil into the
pump port. Apply grease to the pump or the coupling shaft
extension, if present or accessible. Viking suggests rotating the
pump shaft every 30 days to circulate the oil in the pump. The
coupling should be stored in a dry area. Note: if the liquid to
be pumped reacts with oil, use an acceptable alternate.
SUGGESTED REPAIR TOOLS: The following tools are
required to properly repair a Mag Drive pump. These tools
are in addition to standard mechanics tools such as open end
wrenches, socket set, pliers, screw drivers, etc. Most items can
