• Alignment of the pump and motor should be checked.
• Suction line should be checked for no air leakage and   jamming of the dirt in filter.
• If there is a pressure drop, the relief valve should be further      screwed in till desired pressure is achieved. If this does not   give any result, then there should be a considerate wear in the   plates, which should be replaced.
• Leakage, if any, on end covers should be eliminated by   tightening bolts.


• If a pressure drop is too much, the gears or the wear plates    should be changed as the case may be due to excess wear    on them.
• Oil seal should be replaced if there is leakage from the
   drive end.
• On dismantling, if the body shows wear, then it should be sent   back to us for placement. This will be a very long run only.
• Bearings, if found worn out, should be replaced.


• If the pump gets jammed in running position, then loosen all    the bolts by half a turn (this will also be in the case of pumps    with bush bearings) and try to rotate the pump shaft with pipe    spanner. if it rotate then start pump and allow it to run    smoothly and lighten the bolts slowly till there is no jamming.
•  if the rotor does not rotate, then dismantling is necessary.
• Where the pump is excessively heated in the initial running,    and jamming is caused, allow it to cool down to the    temperature till the jamming is eliminated.
• At the time of commissioning, under no circumstance the pump    should be dismantled due to any fault whatsoever without    consulting the manufacturers.
• At the commissioning stage, if the shaft is found tight, try to    rotate the shaft with the help of pipe wrench. if it rotates with    the pipe wrench, then tightness should be considered as    normal and the pump can be started without any trouble.
