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 precaution- ary measures may result in serious injury or death.

ROTATION: Viking Mag Drive® pumps are designed to run in either direction. See PUMP ROTATION, page 11.

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.

2.Relief valves are mounted as standard on the casing of AS, AK,AL,KE and KKE size pumps.

3.If the pump rotation is to be reversed during operation, pressure protection must be provided on both sides of the pump.

4.The relief valve adjusting screw cap must always point towards the suction side of the pump. See Figure 3. If the pump rotation is reversed, remove the pressure relief valve and turn end for end (see PUMP ROTATION, page 11 for additional information.

5.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.
