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
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).
RUNNING T DIRECTION TO THE DESIGNATED DIRECTION MAY RESULT IN SERIOUS INJURY OR DEATH.
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.
TSM 343.1 ISSUE D PAGE 2 OF 13
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
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.
4. A strainer on the suction side of the pump should always
protect the pump without causing excessive pressure
areful not to over tighten fittings as this can cause
is needed for proper connection. Do not use Teflon tape.

be considered in any pumping system. The straining will keep foreign matter from entering the pump. The strainer mesh or perforation size should be as fine as possible to
drop. Use of a strainer is particularly important at start up to help clean the system of weld beads, pipe scale and other foreign objects.
5. A pressure relief valve is required in the discharge line.

6. Pump must not be used to support piping. Weight of pipe
must be carried by hangers, supports, stands, etc.
7. When fastening to the pump to impose any strain on
pump casing. "Springing" or "drawing" piping up to pump will cause distortion; possible misalignment and probable rapid wear of pump. Do not use pipe to correct errors in piping layout or assembly.
8. All joints of piping system must be tight; liquid thread
sealant will help assure leak free threaded joints. Loose joints result in liquid leaks or suction side leaks. Air leaks make the pump noisy and reduce flow. CAUTION: Be
c cracked joints. One full turn beyond hand tight is all that
(viewed from shaft end)
FIGURE 3
The cause of many pumping problems can be traced to suction piping. It should always be as large in diameter and as short in length as possible.
Before starting layout and installation of your piping system, consider the following points:
1. Never use piping smaller than pump port connections.
Piping larger in diameter than the port connection is sometimes is required to reduce suction losses.
2. Be sure the inside of pipe is clean before installing.
3. When approaching an obstacle in the suction line, go
around instead of over it. Going over obstacle creates an air pocket. Where practical slope piping, slope piping so no air or liquid pockets will be formed. Air pockets in suction line make it hard for the pump to prime.
Reduced friction makes over tightening very easy and will result in cracked ports.
9. Drive alignment must be checked after piping is hooked
up.
10. Provide a pressure relief device if any part of a pump and
piping system that can be valved off, thus completely isolated. A rise in temperature will cause liquid to expand. With no provision for pressure relief in the closed off section, there is a chance that the pump or piping will rupture.

PLACE.
FAILURE TO PROPERLY MOUNT GUARDS MAY RESULT IN SERIOUS INJURY OR DEATH.
Before pushing "start" button, check the following:
1. Vacuum and pressure gauges (liquid filled) are mounted
on or near the pump. Gauges are the quickest and most accurate way of finding out what is happening in the pump.

DISASSEMBLY OF MD-A2, MD-A8, MD-B15, or MD-B40 COUPLINGS
1.
Read all of the instructions before proceeding with
disassembly of the coupling and/or pump. Remove
piping to ports and remove the mounting capscrews securing pump to bracket. Support larger pumps with overhead hoist if possible. Remove pump from coupling bracket. See FIGURE 6 on page 4.
2. Canister will probably be full of liquid, use care while
removing from pump and pull straight off. Loosen both setscrews and pull off inner magnet assembly. MD-A2 and MD-A8 couplings require removing the pipe plug in pump bracket to gain access to the setscrews holding the inner magnet.
Don't forget this is a very powerful magnet. Do not remove O-ring on bracket unless you plan to replace - especially the encapsulated O-rings. Follow instructions in ASSEMBLY
for installation of a new Teflon®
encapsulated O-ring.
3. You should be able to visually inspect other magnets
from end of bracket. If removal is necessary, start by removing (4) capscrews and separating from motor or
bearing carrier. Loosen setscrews in outer magnet
assembly to pull assembly off shaft.

2. Check Pump alignment (See page 3).
3. Check piping to be sure there is no strain on the pump
casing.
4. Rotate the pump shaft by hand to be sure it turns freely.
55. Motor has been jogged and is running in the correct
direction. Refer to "General" on page 2.
6. Pressure relief valve is installed properly.
7. Suction piping is connected and tight, and valves are
open.
8. Make sure discharge piping is connected and tight,
valves are open and, and end of shaft is below liquid level.
9. All guards are in place.
10. The above checklist is a general guideline to be used
prior to starting pump. Since Viking pump cannot foresee every application for our product and possible system design, final responsibility is with the user. The pump must be utilized within the catalog specifications and the pump system must be designed to provide safe working conditions.
Push the "start" button. Pump should begin to deliver liquid within 15 seconds!
If the pump does not deliver liquid, push the stop button. Do
not run the pump without liquid flow longer than 30 seconds because pump or coupling could be damaged or ruined.
Review steps just outlined. Consider what suction and
discharge gauges indicate. If everything appears in order, put more liquid in the pump suction port. See item 6 on page 3. Push the start button. If nothing happens within 30 seconds, stop the pump. The pump is not a compressor and will not build up much air pressure. It may be necessary to vent the discharge line until liquid begins to flow. Use a safe venting procedure especially when handling hazardous liquids.
If the pump still does not deliver liquid, consider one or more of the following:
1. Suction line air leaks; vacuum gauge reading should help
determine if this is the problem.
2. End of suction pipe not submerged deep enough in liquid.
3. Suction lift is too great or suction piping is too small.
4. Liquid is vaporizing in the suction line before it gets to the
pump.
5. Magnetic coupling is decoupling for some reason.
If after consideration of these points, the pump still does not deliver liquid, review all points given under START UP and read through the TROUBLESHOOTING guide and try again. If pump still will not deliver liquid, contact your Viking Pump supplier.
SUGGESTED REPAIR TOOLS: The following are required to properly repair a RP Series Mag Drive pump. The tools are in addition to standard mechanics tools such as open end wrenches, pliers, screw drivers, etc. Most of the items can be obtained from an industrial supply house.
