REPLACEMENT OF GLAND PACKING OF PUMPS AND REACTORS

1.0   PURPOSE:
    
    To describe a  standard operating procedure for replacement  of gland packing of pumps and reactors.
    
2.0    SCOPE:
    
    The standard operating procedure describes in detail the method of replacing  gland packing of pumps and reactors in the plant.
    
3.0    RESPONSIBILITY:
    
    The responsibility of replacing the gland packing  of pumps and  reactors  lies  with the staff of rank not  lower  than  junior utility operator of maintenance department.
    
    The  responsibility of preparing, reviewing  and approving  thestandard  operating  procedure lies with the  Manager  -  Maintenance,  Head of Production and Head of QAD respectively.
    
4.0    METHOD:
    
4.1    Isolate the equipment electrically.
    
4.2    Close  the  suction and discharge valves in case of  pumps  and drain the liquid.
    
4.3    Open the gland follower.
    
4.4    Take  out all the old gland ropes with a metallic hook.
    
4.5    Clean the stuffing box thoroughly with cloth.
    
4.6    Take a new gland rope of suitable size. 
    
4.7    Cut  the gland rope  into pieces of required length and  insert only  one  at a time inside the stuffing box with the  help  of gland follower.
    
4.8    Ensure  that the joints  of all packing rings are  diametrically  opposite.
    
4.9    Insert required number of rings and tighten the gland  follower suitably.
    
4.10    Open  the  suction and delivery valves, in case of  pumps  and restore the power supply to the equipment.
    
4.11    Start the pump/reactor, if the gland leaks, slowly tighten  the gland  follower bolts till the leakage is arrested  in  running condition.
