SPECIAL INFoRMATIoN

DANGER !

Before opening any Viking pump liquid cham-

ber (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 Mag Drive® pumps are designed to run

in either direction. See

“Pump Rotation”, page 9.

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. Do not rely on decoupling of magnets for

protection from over pressure; this may result in damage

to the magnets, pump, or other equipment.
