INSTALLATION
General
The following items must be considered prior to pump installation:
1.
Location - locate the pump as close as possible to the liquid supply. If possible locate the
pump below the liquid supply. Viking pumps are self-priming; but the better the suction
conditions, the better the pump will perform.
2.
Accessibility - the pump must be accessible for inspection, maintenance and repair.
3.
Suction/Discharge - SG Series pumps are designed for clockwise rotation as standard
(viewed from end of shaft). Refer to Figure 1.
4.
Pressure Relief Valve - the SG Series is a positive displacement pump and requires some
form of over pressure protection. Without pressure protection, if the discharge line is
blocked or becomes closed, pressure will build up until the motor stalls, drive equipment
fails, a pump part breaks, or the piping and/or other equipment in the system bursts.
To prevent the possibility of any one or more of the above from occurring, the use of a
pressure relief valve is recommended.
5.
Storage - drain the pump and apply a light coat of non-detergent SAE 30 weight oil to all
internal pump parts. Apply grease to the pump shaft extension. Viking suggests rotating
the pump shaft by hand one complete revolution every 30 days to circulate the oil.
