BA series pumps
Troubleshooting tables 1401
10.2
Problem Cause Possible solution
Pump provides
insufficient
capacity
Gas or air is released from the liquid Ensure that the liquid flows more slowly/
smoothly
Air pockets form in the suction line Eliminate air entrapment to the extent
possible
Inlet of the suction pipe is insufficiently
submerged
Submerge the suction line more deeply
Incorrect direction of rotation Reverse direction of rotation
The wear plate/ring or impeller is worn Adjust or replace wear parts
The impeller is damaged Repair or replace
Manometric suction height undercalculated Place pump higher, if possible
Otherwise: use a different type of pump
The suction height is too great or there is
too little difference between the geometric
height and the vapour tension of the liquid
(NPSH too low)
Place pump at a lower height
Otherwise: use a different type of pump
The operating speed is too low Increase speed
The suction pipe is clogged Clean
The liquid has a higher s.g. or viscosity than
that for which the pump is intended
use a different type of pump
There is a leak in the suction pipe Eliminate leak
Non-return valve is not opening all the way Make sure the valve has a sufficient flow
capacity
