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 the 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 the above listed

precautionary measures may result in

serious injury or death.

ROTATION:
See

figure 3. Viking 4076/4176 pumps are directional

due to the loading groove in the head. If rotation is to be

reversed, the head and pin assembly will have to be replaced

and pump relief valve must be reversed so adjusting screw

cap always points to suction side of pump. Standard rotation

is clockwise, as viewed from the shaft end.

PRESSURE RELIEF VALVES:
Relief valves are mounted on the casing.
Pumps not furnished with a relief valve must be provided with

some means of pressure protection (inline pressure relief

valve, torque limiting device, or rupture disk).
If pump rotation is to be reversed during operation, pressure

protection must be provided on both sides of the pump. See

also “

rOTaTiON”.

Relief valve adjusting screw cap must always point towards

the suction side of the pump.
Pressure relief valves are intended for use as protection for

the pump only and should not be used to control pump flow

or regulate discharge pressure.

Viking 4076/4176 pumps are designed for long, trouble-free

service life under a variety of application conditions with a

minimum of maintenance. The following points will help

provide long service life.
BUSHINGS:
Note that the bushings used in this pump do not require any

external source of lubricant.
CLEANING THE PUMP:
Keep the pump as clean as possible. This will facilitate

inspection, adjustment and repair work and help prevent

overlooking a dirt covered grease fitting.
STORAGE:
If a new pump is to be stored, or not used for six months or

more, pump must be drained and a light coat of non-detergent

SAE 30 weight oil must be applied to all internal pump parts.

Lubricate the fittings and 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.
SUGGESTED REPAIR TOOLS:
The following tools must be available to properly repair

Viking series 4076/4176 pumps. These tools are in addition

to standard mechanics’ tools such as open end wrenches,

pliers and screw drivers. Most items can be obtained from an

industrial supply house.
1. Soft headed hammer

2. Allen wrenches

3. Bearing locknut spanner wrench

4. Spanner wrench, adjustable pin type for use on bearing

housing end cap

5. Brass bar or wood block

6. Arbor press
