SPECIAL INFORMATION
DANGER !
Before opening any Viking pump liquid chamber (pumping chamber, reservoir, relief valve adjusting cap fitting, etc.) Be sure:
This bulletin deals exclusively with Pump Models C, F, FH32 and C, F, FH432 General Purpose Pumps. Refer to Figures 1, 2, 5, and 7 for general configuration and nomenclature used in this bulletin.
All pumps can be furnished with either a mechanical seal or packing. A mechanically sealed pump can be changed to a packed pump by removing the mechanical seal and inserting the packing spring, inner packing gland, packing and outer packing gland. The mechanical seal pump is dimensionally interchangeable with the packed pump.

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.

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.

SPECIAL INFORMATION
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. This series of pumps may be equipped with an integral pressure relief valve. Standard configuration is for clockwise rotation (suction on the right viewing the shaft end of the pump) but it also may be ordered for counter clockwise rotation. The valve cannot be reversed for opposite rotation.
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.
5. Pressure relief valves should not 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.
SUGGESTED REPAIR TOOLS: The following tools must be available to properly repair Series 32 and 432 pumps. These 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.
1. Soft Headed hammer
2. Allen wrenches (some mechanical seals and set collars)
3. Packing extractor, flexible for 1/4” packing
(2-810-049-999)
4. Brass bar
5. Arbor press
6. Standard 5/16” 12 point socket
DISASSEMBLY
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.
MAINTENANCE
The Series 32 and 432 pumps are designed for long trouble free life under a wide variety of application conditions with minimum maintenance, however, the following should be considered.
1. LUBRICATION – External lubrication not required for this series of pumps. The liquid being pumped lubricates the internal bearings in the pump.
2. PACKING ADJUSTMENT – These pumps are designed with a packing spring to maintain a constant load on the packing; no external adjustment is possible. When leakage becomes excessive the packing must be replaced. Refer to re-assembly instruction for proper installation of packing.
4. CLEANING THE PUMP – It is good practice to keep the pump as clean as possible. This will facilitate inspection, adjustment and repair work.
5. STORAGE – If the pump is to be stored or not used for any appreciable length of time it should be drained and a light coat of lubricating and preservative oil should be applied to the internal parts.
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.
