INTRODUCTION
General
1. Location - locate the pump as close as possible to the supply of the liquid being pumped. 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 - Hi-Low Double pumps are designed for clockwise rotation only (viewed from shaft end). Refer to Figure 1.
4. Pump Life - pump life is a factor of many parameters, mainly pressure, speed and duty cycle. Temperature, contamination and type of hydraulic oil also have a definite effect.
5. Hydraulic Oil - Viking recommends using industrial grade hydraulic oil. Temperature must not exceed 150 ºF for optimum life of hydraulic oil. Operating viscosity must be between 100 and 300 SSU.
6. Filter / Strainer - on a hydraulic system, use a return line filter with a maximum 10 micron rating to keep the system clean and free of contaminating elements. A 100 mesh strainer is recommended in the suction line.
7. Pressure Relief Valve - a pressure relief device must be installed in the system to provide over-pressure protection. If a line is blocked or closed, pressure builds up until the motor stalls, drive equipment fails, a pump part breaks or piping bursts.
8. Discharge Line - select discharge piping, hoses and fittings rated for maximum system pressure.
9. Storage - if the pump is to be stored, 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.

REPAIR
1. Parts For A Preventative Maintenance Program -
- Mechanical Seal or Lipseal(s) (Not applicable for Mag Drive pumps)
- O-rings
2. Parts For A Major Overhaul - The Viking Spur Gear series pumps have very tight clearances and precision machining tolerances, and wear on any of the parts will typically indicate that most of the critical parts are worn. Therefore, if wear is found on any of the pump parts, Viking recommends replacing the entire pump. Always supply the serial number from your pump nameplate when requesting a replacement.

WARNING
Danger - Failure to follow the indicated
instruction may result in serious injury
!
or death.
BEFORE opening any liquid chamber (pumping chamber, reservoir, relief valve adjusting cap fitting, etc.) be sure that :
● Any pressure in the chamber has been completely vented through the suction or discharge lines or other appropriate openings or connections.
● The pump drive system means (motor, turbine, engine, etc.) has been “locked out” or otherwise been made non-operational so that it cannot be started while work is being done on the pump.
● You know what material the pump has been handling, have obtained a material safety data sheet (MSDS) for the material, and understand and follow all precautions appropriate for the safe handling of the material.
BEFORE operating the pump, be sure all drive guards are in place.
DO NOT operate pump if the suction or discharge piping is not connected.
DO NOT place fingers into the pumping chamber or its connection ports or into any part of the drive train if there is any possibility of the pump shafts being rotated.
DO NOT exceed the pumps rated pressure, speed, and temperature, or change the system/duty parameters from those the pump was originally supplied, without confirming its suitability for the new service.
BEFORE operating the pump, be sure that:
● It is clean and free from debris
● all valves in the suction and discharge pipelines
are fully opened.
● All piping connected to the pump is fully supported
and correctly aligned with the pump.
● Pump rotation is correct for the desired direction
of flow.

WARNING
Warning - In addition to possible serious
injury or death, failure to follow the indicated instruction may cause damage to pump and/or other equipment.
INSTALL pressure gauges/sensors next to the pump suction and discharge connections to monitor pressures.
USE extreme caution when lifting the pump. Suitable lifting devices should be used when appropriate. Lifting eyes installed on the pump must be used only to lift the pump, not the pump with drive and/or base plate. If the pump is mounted on a base plate, the base plate must be used for all lifting purposes. If slings are used for lifting, they must be safely and securely attached. For weight of the pump alone (which does not include the drive and/or base plate) refer to the Viking Pump product catalog.
DO NOT attempt to dismantle a pressure relief valve that has not had the spring pressure relieved or is mounted on a pump that is operating.
AVOID contact with hot areas of the pump and/or drive. Certain operating conditions, temperature control devices (jackets, heat-tracing, etc.), improper installation, improper operation, and improper maintenance can all cause high temperatures on the pump and/or drive.
THE PUMP must be provided with pressure protection. This may be provided through a relief valve mounted directly on the pump, an in-line pressure relief valve, a torque limiting device, or a rupture disk. If pump rotation may be reversed during operation, pressure protection must be provided on both sides of pump. Relief valve adjusting screw caps must always point towards suction side of the pump. If pump rotation is reversed, position of the relief valve must be changed. Pressure relief valves cannot be used to control pump flow or regulate discharge pressure. For additional information, refer to Viking Pump’s Technical Service Manual TSM 000 and Engineering Service Bulletin ESB-31.
THE PUMP must be installed in a matter that allows safe access for routine maintenance and for inspection during operation to check for leakage and monitor pump operation.

INSTALLATION
Mounting
1. Surfaces to which the pump mounts against must be
clean and flat.
2. Use SAE Grade 5 or better capscrews to mount the pump.
3. The 4 mounting capscrews for GP-04 and GP-05 pumps must have a minimum of ½ inch engagement and must be torqued evenly to 12-15 ft.-lbs.
4. The 2 mounting capscrews for the SG-07 pumps must have a minimum of ½ inch thread engagement and must be torqued evenly to 50-55 ft.-lbs.
5. Do not strike or press the pump drive coupling half to install on the pump shaft. Damage to the pump or coupling may result. If the coupling does not slide onto the pump shaft, inspect the coupling bore, shaft and key for nicks or burrs and remove if present.
6. Once the pump has been mounted, place a small amount of compatible liquid into the suction port and turn by hand to ensure the pump turns freely.
Alignment
Check alignment after mounting.
If the unit has a flexible coupling, remove any coupling guards or covers and check alignment of coupling halves. A straight edge (a piece of key stock will work) across the coupling must rest evenly on both rims at the top, bottom and sides. See Figure 3.
USE STRAIGHT EDGE. THESE SURFACES MUST BE PARALLEL.
CHECK WIDTH BETWEEN THESE SURFACES WITH INSIDE CALLIPERS OR FEELER GAUGE TO BE CERTAIN THE FACES ARE EQUAL DISTANCE APART AND PARALLEL.

Danger !
Before starting pump, be sure all drive equipment guards are in place.
Failure to properly mount guards may result in seri­ous injury or death.
Piping/Hose
The cause of many pumping problems can be traced to the suction piping. It should always be as large in diameter and as short in length as possible.
Before starting the layout and installation of your piping system, consider the following points:
1. Never use piping smaller than the pump port connections. Piping larger in diameter than the port connection is sometimes required to reduce friction losses.
2. Be sure the inside of the pipe is clean before installing.
3. Do not use galvanized piping.
4. When approaching an obstacle in the suction line,
go around instead of over it. Going over an obstacle may create an air pocket. Where practical, slope the piping so no air or liquid pockets will be formed. Air pockets in the suction line make it hard for the pump to prime.
5. Viking recommends using a strainer on the suction side of the pump. The strainer will keep foreign objects from going into the pump. A 100 mesh strainer is recommended. Provisions must be made for cleaning the strainer. Use of a strainer is particularly important at start up to help clean the system of weld beads, pipe scale and other foreign objects.
6. On a hydraulic system, it is recommended that a return line filter be installed having a maximum 10 micron rating.
7. A pressure relief valve is required in the discharge line. See Pressure Relief Valves, General page 1 item 7.
8. The pump must not be used to support piping. Weight of the pipe must be carried by hangers, supports, stands, etc.
9. When fastening to the pump do not impose any strain on the pump casing. “Springing” or “drawing” piping up to the pump will cause distortion, possible misalignment and probable rapid wear of the pump. Do not use the pump to correct errors in the piping layout or assembly.
10. 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 careful not to over tighten fittings as this can cause cracked joints. Do not use PTFE / plumber’s tape. Reduced friction makes over tightening very easy and will result in cracked ports.
11. Drive alignment must be checked after the piping is hooked up.
