Viking Pump TSM280: Duralobe (Discontinued) - Manual (Page 19)

- Ensure lubrication is provided for both pump and drive. Duralobe ®
pumps are shipped without oil and should be filled to the level of the oil
sight glass which must be installed in the upper tapped hole in the side
of the gearbox cover, refer to section 5.3 for pump oil capacities and
grades.
- If an external relief valve is incorporated in the system check that it is
set correctly. For start up purposes it is considered good practice to set
the relief valve lower than the system design pressure. On completion
of start up the relief valve should be reset to the required setting for the
application. The required setting should never exceed the lower of
either the pumps maximum pressure rating or the system design
pressure. For setting integral relief valves, refer to sections 3.8.1 and
3.8.2.
- Ensure both suction and discharge valves are fully open, and pipework
is free from all obstructions. Duralobe® pumps are of the positive
displacement type and should therefore never be operated against a
closed valve as this would result in pressure overload, resulting in
damage to the pump and possibly the system.
- Ensure rotation of the drive shaft is correct for the direction of flow
required, see Fig 8.

-Ensure product is available in the tank before starting pump. This is
very important for pumps installed with unflushed product seals as
these sealing arrangements must never be allowed to run dry.
-Before beginning operation it is considered good practice to
momentarily start/stop the pump to check the direction of rotation and
ensure that the pump is free of obstructions. Once this has been
carried out, begin operation keeping a visual check on suction and
discharge pressure gauges and monitor pump temperature and power
absorbed where possible.
