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

not available with a relief valve.
