FIGURE 6H – MISALIGNMENT & FASTENER TORQUE VALUES

Final Alignment

Final alignment cannot be accomplished until

the pump has been operated initially for a

sufficient length of time to attain operating

temperature. When normal operating

temperature has been attained, secure the

pump to re-check alignment and compensate

for temperature accordingly. See Alignment

Section.

WARNING: Rotating Components

Hazard

Do not operate pump without all guards in place.

Failure to follow these instructions could result in

serious personal injury or death and property

damage.

WARNING: Coupling Failure

Do not operate pump with coupling out of

alignment. Ensure final coupling alignment is

within the values stated above or according to the

coupling manufacturer’s instructions. Coupling,

pump, or driver failure may occur.

Failure to follow these instructions could result in

serious personal injury or death and property

damage.

OPTIONAL Alignment Procedure

If desired, the pump and motor feet can be

doweled to the base after final alignment is

complete. This should not be done until the

unit has been run for a sufficient length of

time and alignment is within the tolerance.

See Doweling Section.

CAUTION: Extreme Temperature and/or

Flying Debris Hazard

Eye protection and gloves required. Failure to

follow these instructions could result in property

damage and/or moderate personal injury.

NOTE: Pump may have been doweled to

base at factory.
