pump and isolation valve. The isolation valve is used for priming, starting, and
shutting down the system. If you use pipe diameter increasers, place them
between the pump and the check valve.
ALIGNMENT
The alignment at the pump and drive shaft is one of the most important
considerations in the pump installation.
WARNING!
Lock out pump driver. Failure to do so
could result in serious personal injury.
î TO ALIGN THE PUMP
1. Use flexible spacer couplings to achieve proper alignment.
2. Check and adjust the parallel and angular alignment to within .005 inches
prior to connecting the coupling halves.
3. Jog the motor to check rotation. Its arrow should match up with the arrow on
the pump.
4. Install a coupling guard when the pump is aligned.
Pumps in hot service will need an alignment check at operating temperatures.
STUFFING BOX
Packed Box
Braided packing is supplied as standard equipment on all pumps. Install gland
bolt nuts finger-tight only. Adjust the gland bolt nuts during start-up to achieve
40-65 drops of leakage per minute. Specific packing type is dependent on pH,
temperature, etc. of the liquid being pumped.
