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.

SPECIAL INFORMATION
DANGER !
Before opening any Viking pump liquid chamber (pumping chamber, reservoir, relief valve adjusting cap fitting, etc.) Be sure:
1. That any pressure in the chamber has been completely vented through the 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.
ROTATION: Viking pumps operate equally well in a clockwise or counterclockwise rotation. Shaft rotation determines which port is suction and which is discharge. Port in area where pumping elements (gear teeth) come out of mesh is suction port.
PRESSURE RELIEF VALVES:
1. Viking pumps are positive displacement pumps and must be provided with some sort of pressure protection. This may be a relief valve mounted directly on the pump, an inline pressure relief valve, a torque limiting device or a rupture disk.
2. There are relief valve options available on those pump models designed to accept a relief valve. Options may include a return to tank relief valve and a jacketed relief valve. Pumps equipped with a jacketed head plate are generally not available with a relief valve.
3. If pump rotation is reversed during operation, pressure protection must be provided on both sides of pump.
4. Relief valve adjusting screw cap must always point towards suction side of pump. If pump rotation is reversed, remove pressure relief valve and turn end for end.
5. Pressure relief valves cannot be used to control pump flow or regulate discharge pressure.
For additional information on pressure relief valves, Refer
to Technical Service Manual TSM000 and Engineering Service Bulletin ESB-31.
Jacketing of the bracket and head provide large chambers at both ends of the pumping chamber and around the stuffing box for temperature control of the product in the pump.
SPECIAL MECHANICAL SEALS:
Extra care should be taken in repair of these pumps. Be sure to read and follow all special instructions supplied with your pump.
MAINTENANCE
Series 124E, 124EH, 224A, 4224A, 224AE, 4224AE, 224AH, 4224AH, 4224B, 226A, 4226A, 223A, 4223A, 227A, and 4227A pumps are designed for long, trouble-free service life under a wide variety of application conditions with a minimum of maintenance. The points listed below will help provide long service life.
LUBRICATION: External lubrication must be applied slowly with a hand gun to all lubrication fittings every 500 hours of operation with multi-purpose grease, NLGI # 2. Refer to Engineering Service Bulletin ESB-515. Consult factory with specific lubrication questions. Applications involving very high or low temperatures will require other types of lubrication.
PACKING ADJUSTMENT: New packed pumps require initial packing adjustment to control leakage as packing “runs in”. Make initial adjustments carefully and do not over -tighten packing gland. After initial adjustment, inspection will reveal need for packing gland adjustment or packing replacement. Refer to instructions under “Disassembly” and “Assembly”, page 7, regarding repacking pump.
CLEANING PUMP: Keep pump as clean as possible. This will facilitate inspection, adjustment and repair work and help prevent overlooking a dirt covered grease fitting.
STORAGE: If pump is to be stored, or not used for six months or more, pump must be drained and a light coat of light oil must be applied to all internal pump parts.
Lubricate fittings and apply grease to pump shaft extension. Viking suggests rotating pump shaft by hand one complete revolution every 30 days to circulate the oil. Tighten all pump assembly bolts before putting pump in service after being stored.
SUGGESTED REPAIR TOOLS: The following tools must be available to properly repair series 124E, 124EH, 224A, 4224A, 224AE, 4224AE, 224AH, 4224AH, 4224B, 226A, 4226A, 223A, 4223A, 227A, and 4227A pumps.

This seal type can be installed as an alternate to the cartridge mechanical seal. The seal is setscrew driven, is simple to install and good performance will result if care is taken during installation.
For complete pump disassembly and assembly, see pages 7 and 8. For Step 6, disassembly, remove the appropriate nuts, capscrews, seal holder and seal seat. Remove the pipe plug in the bracket and loosen the setscrews holding the mechanical seal rotary member to the shaft. This must be done before the rotor is removed to avoid damage to the seal and the rotor shaft.
The following steps are for mechanical seal assembly.
1. Clean rotor shaft and seal housing bore. Make sure they are free of dirt, grit and scratches. Gently radius leading edge of the shaft diameter over which seal is to be placed.
Never touch mechanical seal faces with anything except clean hands or clean cloth. Minute particles can scratch the seal faces and cause leakage.
2. Place tapered installation sleeve on the shaft. Coat tapered sleeve and inside of the rotary member with a generous quantity of light oil. Grease is not recommended. Start rotary member on shaft and over tapered sleeve. Refer to Figure 5.
