DANGER !

Before opening any Viking pump liquid chamber

(pumping chamber, reservoir, 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.

SPECIAL INFORMATION ROTATION TAPERED ROLLER BEARINGS Viking Industrial Rotary Lobe pumps may be operated in either a clockwise or counterclockwise rotation (clockwise rotation is standard). Rotation is determined by viewing the pump from the shaft end as shown in Figure 3. The circulation line provided vents the seal chamber to the inlet port. When reversing the rotation on the pump, the seal chamber will experience an increase in pressure, which may affect seal performance.

MECHANICAL SEAL INFORMATION Optional Cartridge Lipseal Seal Replacement The Industrial Lobe series pump can be supplied with a variety of mechanical sealing configurations and materials. The cartridge mechanical seal is considered standard construction. NOTE: Good radial alignment is required for proper operation of the seals. This is accomplished by the use of centering tabs provided with each seal. Turn the tabs inward when installing or removing the seal.
