SPECIAL INfORMATION
Rotation:
Although shaft rotation determines which port is suction and
which is discharge, Viking magnetic drive composite pumps
are designed to run in a designated direction (indicated on
pump decal).
Pressure Relief Valves:
1. Relief valves are mounted on the head or casing of all
RP series composite pumps.
2. The RP series is a positive displacement pump and
requires some sort of over pressure protection. Without
over pressure protection, the following is likely to occur:
motor stalls, drive equipment fails, a pump part breaks
and the piping and/or equipment in the system bursts.
This may be an internal relief valve.
3. If a relief valve is not furnished on the pump, some means
of over pressure protection such as an in-line relief valve
should be provided.
4. If pump rotation is to be reversed during normal
operation, pressure protection must be provided on both
sides of pump.
5. Relief valve adjusting screw cap must always point
towards suction side of pump.
6. Pressure relief valves cannot be used to control flow to
regulate pressure.
For additional information on pressure relief valves, refer to
Technical Service Manual TSM 000 and Engineering Service
Bulletin ESB-31.
INSTALLATION
General
The following items must be considered prior to pump
installation:
1. Location - locate the pump as close as possible to supply
of liquid being pumped. If possible locate pump below
liquid supply. Viking pumps are self-priming; but, the
better the suction conditions the better the pump will
perform.
2. Accessibility - 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 3.
Mounting
1. The pump mounting surface must be clean and flat.
2. Use SAE Grade 5 or better capscrews to mount pump.
3. The mounting capscrews for RP-05 & RP-07 pumps must
have a minimum of ½ inch thread engagement.
4. Mechanical Seal and Lip Seals RP Series pumps are
designed to be used with jaw type couplings that do not
induce axial thrust on the pump shaft. If an improper type
coupling is used, internal damage may result.
5. Do not strike or press inner magnet coupling half to install
on the pump shaft. Damage to pump or coupling may
result if coupling does not slide onto pump shaft, inspect
coupling bore, shaft and key for nicks or burrs and
remove if present.
6. Once pump has been mounted, place a small amount of
compatible liquid into suction port and turn by hand to
ensure pump turns freely.
Alignment
Check alignment after mounting of units with a bearing
carrier.
1. If unit has flexible coupling, remove any coupling guards
or covers and check alignment of coupling halves. A
straight edge (piece of key stalk will work) across coupling
must rest evenly on both rims at top, bottom and sides.
See Figure 4.
2. Make final check on alignment after piping is hooked up.
Replace the guards.
DANGER
BEFORE OPENING ANY VIKING PUMP LIQUID
CHAMBER (PUMPING CHAMBER, RESERVOIR,
RELIEF VALVE ADJUSTING CAP FITTING ETC.)
BE SURE:
1. THAT ANY PRESSURE IN CHAMBER HAS
BEEN COMPLETELY VENTED THROUGH
SUCTION OR DISCHARGE LINES OR OTHER
APPROPRIATE OPENINGS OR
CONNECTIONS.
2. THAT THE DRIVING MEANS (MOTOR,
TURBINE, ENGINE, ETC.) HAS BEEN “LOCKED
OUT” OR MADE NON- OPERATIONAL SO THAT
IT CANNOT BE STARTED WHILE WORK IS
BEING DONE ON PUMP.
3. THAT YOU KNOW WHAT LIQUID THE PUMP
HAS BEEN HANDLING AND THE
PRECAUTIONS NECESSARY TO SAFELY
HANDLE THE LIQUID. OBTAIN A MATERIAL
SAFETY DATA SHEET (MSDS) FOR THE
LIQUID TO BE SURE THESE PRECAUTIONS
ARE UNDERSTOOD.
FAILURE TO FOLLOW ABOVE LISTED
PRECAUTIONARY MEASURES MAY RESULT IN
SERIOUS INJURY OR DEATH.
DANGER
RUNNING THE PUMP IN THE OPPOSITE
DIRECTION TO THE DESIGNATED DIRECTION
MAY RESULT IN SERIOUS INJURY OR DEATH.
