ROTATION: Viking pumps operate equally well in a clockwise

or counterclockwise rotation When rotation changes, the

suction and discharge is reversed
PRESSURE RELIEF VALVES:
1. Viking pumps are positive placement pumps and must be

provided with some sort of pressure protection Series

200-G and 260-G pumps are only available with a return

to tank relief valve

2. If pump rotation is to be reversed during operation,

pressure protection must be provided on both sides of

pump

3. Relief valve adjusting screw cap must always point

towards suction side of pump If pump rotation is

reversed, remove pressure relief valve and either turn

end for end or change position with the cover plate

4. 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.
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

1. lUBRICaTION: Periodic external lubrication should be

applied slowly with a handgun at all lubrication fittings

provided A good quality of general-purpose grease is

satisfactory in the majority of cases; however, applications

involving low temperatures may require other types of

lubricants Suggested frequency of lubrication is once

every 500 hours of operation with multi-purpose grease,

NLGI # 2 Do not over-grease Applications involving

low temperatures will require other types of lubrication

Refer to Engineering Service Bulleting ESB-515

Consult factory with specific lubrication questions

2. END ClEaRaNCE aDJUSTMENT: After long term

operation it is sometimes possible to improve the

performance of the pump, without major repair, through

adjustment of end clearance of the pump Refer to

instructions under assembly of the pump for information

regarding this procedure

DISaSSEMBlY

DaNGER !

Before disassembling a pump or

removing it from the line, be sure the

pump and system are free of lP-Gas. as

an extra precaution, protective clothing

for face and body should be used when

doing this work.

3. ClEaNING ThE PUMP: It is good practice to keep the

pump as clean as possible This will facilitate inspection,

adjustment and repair work and help prevent omission

of lubrication to fittings covered or hidden with dirt

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 Lubricate all fittings
SUGGESTED REPaIR TOOlS: The following tools must

be available to properly repair Series 200 and 260 pumps

These tools are in addition to standard mechanics’ tools such

as open end wrenches, pliers, screwdrivers 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. Mechanical seal installation sleeve
4. Bearing locknut spanner wrench
